Laura K. Donohue, The Future of Foreign Intelligence: Privacy and Surveillance in a Digital Age (New York: OUP, 2016)

By Joel Brenner

(Joel Brenner is a research fellow at the Massachusetts Institute of Technology. He is the former inspector general and senior counsel of the National Security Agency and former head of U.S. counterintelligence under the first three directors of national intelligence. He gratefully acknowledges the assistance of Alexander Loomis of Harvard Law School in preparing this response.)


Professor Donohue has given us a full-throated denunciation of the entire legal framework governing the government’s collection of data about American citizens and permanent residents, whom we call “U.S. Persons.”[1] She contends that in the wake of the digital revolution, current law “is no longer sufficient to guard our rights”[2] – she’s right about that – and that we have actually returned to the untrammeled issuance of general warrants that characterized the eighteenth century British practice that our nation’s Founders rebelled against. She proposes a thorough revision of the laws governing the collection of foreign electronic intelligence within the United States and abroad, and she advocates severe limitations on the collection and access to digital information of any sort. I will address the merits of her arguments – but first a threshold question: Is this really a book about the future of foreign intelligence?

From the half-century leading to the end of the Cold War, the nearly exclusive control by nation-states over the tools of spy craft seemed like a natural monopoly. The complexity of modern cryptography from the 1930s onward put high-end encryption beyond the capability of all but a few intelligence services.[3] Most forms of electronic intelligence gathering — advanced listening devices, sophisticated radars and antennae, and measurement of weaponry signatures, for example — were also developed by governments and were unavailable to most nations. Free-lance and commercial human spying never went away, but they became the exception after Europe was rigidly divided into East-West blocs, and as border controls, which hardly existed before World War I,[4] became the norm.

Between the collapse of the Soviet Union in 1991 and the 9/11 attacks a decade later, the monopoly vanished as the tools of spycraft became the products and instruments of the marketplace. The encryption now found in an ordinary smart phone can be broken only with extraordinary effort, if at all, and its computing power dwarfs anything available to the presidents and premiers of a previous generation. The absolute monopoly of the two Cold War superpowers over high-thrust rocketry and orbital satellites is ancient history. Countries around the world now compete with, or rely on, private companies to do the heavy lifting. The commercial satellite imagery readily available to the public is also jaw-droppingly good, at resolutions that were state secrets only a few years ago. The advantage of states over private enterprises in surveillance, counter-surveillance, and clandestine operations has not disappeared, but the private sector is catching up fast. At the same time, the digitization of information and the consequent explosion of freely available data have both delighted and disoriented us, turning private lives inside out and making secrets extremely difficult to keep for individuals, businesses, and governments alike — including intelligence services. The ubiquity of data has also made open-source intelligence more valuable than ever and has called into question the scope, though not the necessity, of secret intelligence gathering and analysis. The challenges this environment presents to intelligence services are severe.[5] In the wake of these developments, the distinction insisted upon by the grand viziers of Langley, Cambridge Circus, and Moscow Center between intelligence (that’s what you think, with a small “i”) and Intelligence (that’s what we think, with its reifying initial capital) appears risible.

Profound political, ethical, and legal challenges also confront agencies that make a living stealing secrets. Stealing secrets involves breaking the laws of other nations, including friendly ones. In an increasingly integrated world, we can expect new norms, and perhaps laws, to control that kind of activity. Drones and robots also present still-unresolved questions.[6] Profound issues of mission focus are also up for grabs — whether the CIA will continue to be dominated by its para-military side,[7] and whether the National Security Agency (“NSA”) is destined to remain essentially a targeting service for a war machine at the expense of its national intelligence mission.[8] Distinguishing domestic from foreign communications is increasingly difficult, heightening the need to regulate this aspect of foreign intelligence operations.[9]

Opening a book entitled The Future of Foreign Intelligence, this is the platter of issues one would expect on the table. But from this menu, the only dishes Professor Donohue serves up are the government’s access to domestic digital data and the legal difficulties that arise from the inevitable mingling of domestic and foreign communications. Her book thus has little to do with the future of foreign intelligence, and rather than evaluate it as such, we will do better to accept it as the book her subtitle accurately describes: Privacy and Surveillance in the Digital Age. This is not a mere quibble about a title. Her argument is infected with a fundamental confusion between the scope and purpose of the Foreign Intelligence Surveillance Act (“FISA”) and the general regulation of foreign intelligence, and that confusion is reflected on the book’s cover. In any case, privacy and surveillance are topic enough for a brief but passionate argument about the constraints (or as she would say, the lack of constraints) on the government’s ability to vacuum up everyone’s digital exhaust. Professor Donohue shapes this conversation through her teaching and as one of a handful of amici curiae appointed to advise the Foreign Intelligence Surveillance Court (“FISC”) in cases of broad applicability. On these issues her views demand respectful attention.

The Argument

Her arrows are aimed chiefly at two specific targets. The first is the Supreme Court’s “third-party doctrine,” which denies Americans a constitutionally based privacy interest in data they give to third parties, including common carriers and other digital platforms that provide essential services. I enlarge her attack on this doctrine.

Her second major target is the 2008 amendments to the Foreign Intelligence Surveillance Act of 2008[10] (the “FISA Amendments Act” or “FAA”). That law allowed the NSA to collect, without a warrant, communications between targeted foreign citizens and Americans. She and I agree that reforms are needed. But she would go further than I would by subjecting foreign intelligence collection to strict warrant requirements. That proposal misunderstands FISA’s purpose and constitutional limitations

Professor Donohue also presents a jaundiced but, as I will explain, undeveloped view of the area of government operations known as intelligence oversight. Finally, she contends that criminal law and the law governing intelligence gathering have little or nothing to do with one another and that the distinction between them is both meaningful and clear. Her most startling and potentially consequential proposal is to resurrect that doctrine by re-erecting “The Wall” that, until 2002, required the complete separation of criminal investigations from all information gathered using foreign intelligence sources and methods. In my view, the destruction of that barrier was one of the most significant and desirable changes to the organization of the federal government following the attacks of 9/11.

I examine her arguments in this order.

Third-Party Doctrine and Metadata

In the early 1970s, federal authorities served subpoenas on two banks with which a bootlegger named Miller did business. The banks complied. Miller moved unsuccessfully to suppress the banks’ evidence on the grounds that it had been seized without warrants in violation of the Fourth Amendment. He was later convicted of various federal crimes. The Court of Appeals for the Fifth Circuit overturned his conviction, but the Supreme Court reversed. The Court held that

  1. the subpoenaed papers were the bank’s business records,
  2. the bank was required to maintain them under the Bank Secrecy Act of 1970,[11] and
  3. Miller had no reasonable expectation of privacy either in the bank’s copy of the records or in the original checks, which were negotiable instruments used in commercial transactions.[12]

Miller’s holding could easily have been confined to negotiable instruments or to business records maintained under statute. But three years later, in Smith v. Maryland[13] the Supreme Court expanded Miller to cover any information given to third parties. Petitioner Smith had been convicted of robbery based in part on telephone numbers collected from a pen register placed on his phone without a warrant. Holding that he had no Fourth Amendment interest in the phone company’s business records, the Court expressed “doubt that people in general entertain any actual expectation of privacy in the numbers they dial.”[14] For good measure the Court added that if Smith did have such an expectation of privacy, it was not one society was prepared to recognize as reasonable. Smith had “voluntarily conveyed” his dialing information to the phone company[15] and had therefore “assumed the risk” that the company would reveal the information to the police. We now had a broad, clearly articulated third-party doctrine: “This Court consistently has held that a person has no legitimate expectation of privacy in information he voluntarily turns over to third parties.”[16]

Miller and Smith were both based on the “reasonable expectation of privacy” test of Katz v. United States.[17] With rare exceptions,[18] lower courts have repeatedly reaffirmed the third-party doctrine. But as Professor Donohue makes clear, it no longer protects reasonable expectations of privacy. During the 1970s, people only shared information with third parties (other than the bank and the phone company) by handing a box of papers to their lawyers, accountants, or business associates. There were no permanent records of people’s messages to their family and friends. Today, by contrast, nearly all information is routinely digitized and shared with cloud service providers. If your smartphone or laptop is backed up by Google, Apple, or anyone else, you have no constitutional privacy interest in its contents. People increasingly keep all manner of personal and business records “on” their smartphones, which combine the features of filing cabinets, photo albums, contact directories, diaries, credit cards, and so forth all in one place. Dating apps record people’s sexual preferences and romantic liaisons. And unlike the defendant’s phone in Smith, which was tethered to a wall, mobile phones move freely.[19] Mobile phones, especially smartphones, are tracking devices. Uber and Lyft, the weather app, the city transportation app, and many others have little or no value if they do not know exactly where you are. Your mobile phone must also know where you are at all times in order to connect your calls, so it constantly communicates with cell towers even when you’re not on the phone. Companies keep this data and often sell it. Our phones thus record not merely where we are now, but where we have been and how long we were there. Soon, thanks to the third-party doctrine, no one will have a reasonable expectation of privacy in almost anything.[20]

Technological developments notwithstanding, the third-part doctrine was also bad law to begin with. It treats a substantive constitutional right as if it were merely an evidentiary privilege that is automatically lost when shared with anyone else. That view does not reflect reasonable expectations of privacy, and it never did. If you disclose to a third party an otherwise privileged conversation with your lawyer, you lose the privilege. But this is merely a rule of evidence. We do not use the subsequent third-party disclosure to declare that the client had no right to share information in confidence with the lawyer in the first place. Rather, we recognize that lawyer and client, like doctor and patient, communicate in a zone of confidence. The third-party doctrine recognizes no such zone for information that ordinary people must, as a necessity of life, share with companies that promise to protect their privacy.[21] In Miller, for example, the petitioner’s bankers testified that they regarded their customers’ records as confidential,[22] and the prosecution admitted as much.[23] But Miller’s holding effectively eliminated any such confidence that reasonable customers had.[24] In short, the reasonable expectation test of Katz would have fit the facts in Miller like a glove, if the Court had only tried it on.[25]

Miller and Smith thus represent an attempt to define a substantive right through a mechanical, inapt test borrowed consciously or unconsciously from the law of evidence. The attempt was always flawed in principle. But thanks to technological developments putting virtually all our private information in third parties’ hands, it now produces intolerable results. So Professor Donohue is right: Supreme Court precedent does not protect ordinary citizens from government unreasonable intrusions into private lives and requires re-thinking.

Several members of the Court appear to agree, as Justice Scalia’s opinion for the Court and the concurrences in Jones v. United States[26] suggest. Jones presented the question whether attaching a GPS tracking device to a man’s automobile, and subsequently using that device to monitor the vehicle’s movements on public streets, constituted a Fourth Amendment search or seizure. A five-justice majority declined to apply the rule on the narrow ground that, notwithstanding Katz’s expectation of privacy test, the government had trespassed in affixing the device to the vehicle.[27] The majority knew that its disposition of the case left the hard question lurking in the wings: “It may be that achieving the same result through electronic means, without an accompanying trespass, is an unconstitutional invasion of privacy, but the present case does not require us to answer that question.”[28] Justice Sotomayor, who concurred with the majority, wrote separately. “I would ask,” she wrote, “whether people reasonably expect that their movements will be recorded and aggregated in a manner that enables the Government to ascertain, more or less at will, their political and religious beliefs, sexual habits, and so on.” Her implication was clear: “More fundamentally, it may be necessary to reconsider the premise that an individual has no reasonable expectation of privacy in information voluntarily disclosed to third parties.”[29] Justice Alito, joined by Justices Ginsburg, Breyer, and Kagan, had the same concern. “[I]f long- term monitoring can be accomplished without committing a technical trespass — suppose, for example, that the Federal Government required or persuaded auto manufacturers to include a GPS tracking device in every car — the Court’s theory would provide no protection.”[30] We thus had all nine members of the Court expressing discomfort both with the third-party doctrine and its interplay with Katz.[31]

Jones may mark the beginning of the end for an across-the-board third-party doctrine, but the end is unlikely to come at a single stroke. Congress has displayed no enthusiasm for legislating in this area, and courts will be slow to abandon a mechanically applied doctrine that produces clear results.[32] But doctrinal clarity costs too much in today’s digital economy. The third-party doctrine destroys information privacy and yields unreasonable results. It is premised on technologically obsolete assumptions about the world — a point that Professor Donohue makes wonderfully clear — and it was unsound from the beginning.

In its time, Katz expanded individual rights by holding that citizens enjoy a zone of privacy that moves with them. But its reasonable expectation standard should be re-thought. On the one hand, it is insufficient to deal with technological advances that are rapidly destroying expectations of privacy that still seem reasonable to many people; on the other hand, it could be useful in fashioning protections for information that must, as a practical matter, be shared with third parties. Professor Donohue thinks we may be in “a pre-Katz moment,” ripe for a doctrinal shift. When a majority of the Court declares that “Fourth Amendment rights do not rise or fall with the Katz formulation,”[33] she’s probably right.

Collection Under FISA

Professor Donohue mounts three principal attacks on the FAA. First, it authorizes the collection of bulk electronic metadata without a warrant, by which she apparently means a Title III warrant.[34] She asserts this practice is unconstitutional, by which she presumably means that in her view it should be unconstitutional, because she knows that the third-party doctrine, just discussed, denies citizens a Fourth Amendment right to privacy in communications metadata.[35]

Second, she argues that a FISA order that authorizes the collection of large numbers of international communications that begin or terminate in the United States between foreign persons overseas who are associated with terrorism is unconstitutional. Instead, she believes a FISA order must be restricted to single, particularized call or message. She provides no constitutional foundation for her position, and there is none.

Third, she argues that the government’s unrestrained ability to retain and examine lawfully collected intercepts of conversations involving U.S. Persons under section 702 is unconstitutional and should be regulated. Here again Professor Donohue’s arguments about constitutionality are perplexing, at least to this reader, because they are not based on a parsing of constitutional text and Supreme Court decisions as they apply to particular parts of FISA. Instead, she offers a lively disquisition, fully a quarter of the book, on the origins of the Fourth Amendment and the history of general warrants in the run-up to the American Revolution.[36] As a former member of the guild of legal historians, I found this background relevant but, standing alone, unpersuasive. Nevertheless, I agree with her that access to stored 702 data should be regulated, though I am not sure we agree on how.

While I find common ground with several of Professor Donohue’s specific proposals for further FISA reform, I see two major weakness in the foundation of her attacks on FISA collection and thus with her broader argument. The first weakness — in my view, error — is constitutional and legal. It concerns the scope and purpose of the FISA statute, which were limited in their reach by the President’s independent constitutional authority to collect foreign intelligence. The second weakness is partly technological and partly a result of failing to acknowledge the altered intelligence challenge in the form of metastasized terrorism that confronts anyone, regardless of political inclination, who wishes to regulate the monitoring of communications. Before addressing these points, however, a brief history of bulk metadata and FISA collection since the attacks is in order.

Origins of Bulk Collection and the “702 Program”

Shortly after 9/11, the Bush Administration put in place a surveillance program called STELLAR WIND. That program authorized NSA to intercept communications between persons overseas with known terrorist affiliations and persons in the United States. It also authorized the collection of bulk metadata (that is, information about a communication but not its contents)[37] from U.S. telecommunications carriers in order to understand who the persons on the U.S. end of those calls were communicating with. Through link analysis, these metadata connections could be followed for three “hops,” thereby gathering call information about a huge number of domestic calls. The program was authorized by Presidential order, outside the FISA structure. (FISA at that time did not address metadata collection.) But metadata analysis was beginning to play a critical role in wiping out terrorist networks overseas,[38] and the Bush Administration believed it would similarly be critical in rolling up any of those networks that extended into the United States.

By late 2003, however, some government officials had become concerned about the legal authority to collect bulk metadata.[39] Consequently, in July 2004 the collection of bulk Internet metadata quietly was moved under section 214 of the Patriot Act (which amended section 402 of FISA). That statute permits pen registers and trap-and-trace devices, but authorizations for such devices had previously been used only for specific telephone numbers or Internet addresses. However, then-chief judge of the FISC District Judge Coleen Kollar-Kotelly was persuaded that the statute could be used to collect Internet metadata in bulk in real time.[40] Suffice it to say that this was a novel and controversial, if also arguably supportable, interpretation of section 214 that vastly expanded the scope of the government’s statutory power to collect bulk metadata. And it occurred in secret.

The portion of STELLAR WIND relating to the interception of the content of U.S.-foreign calls (but not bulk metadata collection) was exposed by the New York Times in December 2005. The disclosure increased the sense of urgency within the Justice Department’s Office of Legal Counsel that the telephony portion of metadata collection should also be given a firmer and explicit statutory basis.[41] In May 2006 the collection of bulk telephony metadata was moved under section 215 of the Patriot Act, which had amended section 501 of FISA. That statute authorized the government to obtain certain business records through legal process.[42] Technically, this meant that NSA stopped “collecting” telephony metadata in real time as part of its intelligence mission and was instead merely obtaining business records through legal process. Practically speaking, however, there was no difference because the business records went to the government more or less as they were generated. Thanks to the third-party doctrine discussed above, this program was entirely constitutional.

The following year, in August 2007, Congress passed the Protect America Act (“PAA”) to provide clear statutory authority to collect the content of communications between a person overseas and a person in the United States,[43] but that authority expired after only eighteen months. After a hiatus, Congress passed the FAA in July 2008. It remains in effect. Unlike the original FISA, the FAA required a FISA order before a U.S. Person could be targeted, even if that person was overseas, in circumstances where a Title III warrant would be required in a criminal case.[44] This was a significant expansion of FISA’s regulatory scope and, to that extent, an expansion of civil liberty.

But the FAA also created what is often called the “702 Program,” which is one of Professor Donohue’s chief targets. As amended by the FAA,[45] Section 702 permits “the targeting of [non-U.S.] persons reasonably believed to be located outside the United States to acquire foreign intelligence information.”[46] In this context, “foreign intelligence information” mean the contents of communications and not merely metadata. A FISA order is not required for this collection. Rather, the Attorney General and the Director of National Intelligence select what information to “target” and direct electronic communications providers to turn over this information. If the government has “reasonable articulable suspicion” that a foreign person has a terrorist connection, that person may be targeted when they communicate with persons in the United States. If, for example, a known terrorist overseas is having conversations with a U.S. Person in Minneapolis, our agencies may collect that communication. However, an agency may not do so if the purpose of the collection is really to target the person in Minneapolis. That would be “reverse targeting.” Electronic communications service providers may challenge these directives before the FISC and appeal to the FISA Court of Review. By long-standing practice, the database of 702 information may be accessed at any time by intelligence officials without court approval and may be queried with any search term, including U.S. Person identifiers.

Professor Donohue objects vehemently to this program. It appears she would subject 702 collection to the criminal warrant process of Title III. In my view, she reaches this position based on a misunderstanding of FISA’s purpose and an unsupportable view of the constitutional requirements governing foreign intelligence collection.

FISA’s Purpose and Constitutional Requirements

Professor Donohue confuses FISA’s purpose with the general regulation of foreign intelligence. This may account for the book’s inapt title. She asserts: “FISA represented the culmination of a multibranch, multiyear, cross-party initiative directed at bringing the collection of foreign intelligence within a circumscribed legal framework” (my italics).[47] This is not true. Foreign intelligence collection is a broad category, occurring in many ways through a variety of human and technological means and gathered against targets who are overwhelmingly outside the United States. FISA brought under law one element of that enterprise, namely, the collection of (i) electronic foreign intelligence (ii) taken off a wire or from a radio signal (iii) in the United States. That slice of foreign intelligence, because it was collected domestically, could be (and sometimes had been) used to avoid the search-and-seizure strictures of the Fourth Amendment. In the wake of the Church Committee hearings in 1976, Congress enacted FISA to prohibit such evasions.

The Constitutional difficulty with Professor Donohue’s argument about this portion of foreign intelligence is inseparable from this issue of statutory purpose. Contrary to her assertions, foreign intelligence taken from domestic telecommunication networks involves powers granted to two branches of government.[48] Under Article I, Congress has the power to regulate interstate and foreign commerce, including telecommunications (at least when used in commerce).[49] But Congress has long deferred to the view that foreign intelligence collection is an executive function vested in the President under Article II of the Constitution,[50] even though the there is no express provision for it in Article II.[51] Indeed, the President’s power to monitor communications entering and leaving the country has been recognized since Washington’s administration.[52] This is why Congress, in enacting FISA, recognized a reasonableness limitation on its power to control communications entering or leaving the country if they concerned foreign intelligence.[53]  It certainly did not contest the principle that the President has the “exclusive function to command the instruments of national force, at least when turned against the outside world for the security of our society.”[54] The Bush Administration, by acting as if it had the power to conduct the STELLAR WIND program on a long-term, non-emergency basis outside the FISA framework, failed to recognize that it shared constitutional authority over activities involving the telecommunications of the American people. In a mirror image of that error, former Senator Russ Feingold was also wrong to assert, in a flight of rhetorical excess with which Professor Donohue is much enamored, that electronic foreign intelligence is an area of “absolutely clear, exclusive authority adopted by Congress ….”[55] This is wrong.  Like Senator Feingold, Professor Donohue ignores FISA’s purpose and history, which probably accounts for her failure to explain why the standard for obtaining a FISA order, which she criticizes repeatedly, differs from the Title III warrant standard.[56]

Title III was passed in 1968 in response to the Supreme Court’s Katz decision one year earlier.[57] Congress reacted by crafting standards for issuing surveillance warrants sufficient to meet Fourth Amendment standards in criminal cases. Under Title III, a magistrate may issue a warrant authorizing the executive to acquire the contents of a wire, oral, or electronic communication if

(1)  “there is probable cause for belief that an individual is committing, has committed, or is about to commit” certain crimes; and

(2)  if there is probable cause for belief that particular communications concerning that offense will be obtained through such interception”; and

(3)  if “normal investigative procedures have been tried and have failed or reasonably appear to be unlikely to succeed if tried or to be too dangerous”; and

(4)   if (in most cases) “there is probable cause for belief that the facilities from which, or the place where, the wire, oral, or electronic communications are to be intercepted are being used, or are about to be used, in connection with the commission of such offense, or are leased to, listed in the name of, or commonly used by such person.”[58]

Would the imposition of these requirements on foreign intelligence collection be unreasonable? Surely they would be, if only because it would irrationally assume that foreign intelligence may not be collected in the United States unless there were probable cause to believe a crime were involved. A great deal of foreign intelligence does not involve the commission of crimes cognizable in U.S. courts. The Supreme Court has recognized that these statutory requirements are not constitutionally necessary as applied to “domestic security surveillance [, which] may involve different policy and practical considerations from the surveillance of ‘ordinary crime.’”[59] The Court expressed further doubts about constitutional restrictions on collection “with respect to activities of foreign powers or their agents.”[60] In such a conflict, we would arguably be in Justice Jackson’s third category, in which the President could ignore a statute. But Justice Jackson was an eminently practical man, and he might point out that he was writing to decide a particular case, that his taxonomy is not holy writ, and that it did not attempt to resolve all the varieties of problems that might arise in cases of conflicting constitutional power.  As he said, “any actual test of power is likely to depend on the imperatives of events and contemporary imponderables, rather than on abstract theories of law.”[61] He might therefore simply say that where two lawful but different powers both impinge on a single area of governmental activity, Congress must exercise its power in a manner that does unreasonably impinge on the President’s authority – and in this case, on his duty to protect the nation. Either way, there are limits on what Congress can do.

In contrast to Title III, the FISA standard to which Professor Donohue objects was created to deal with an entirely different problem than the investigation of crime, namely, the potential misuse of the President’s power to collect foreign intelligence in the United States. The President has the power to collect foreign intelligence even in the United States without a search warrant.[62] A surveillance operation against a foreign embassy in Washington, for example, has never required a Title III warrant; nor does it now require a FISA order.[63] However, if that power is abused to collect against citizens on the pretext, for example, that the citizen was or might be a member of a foreign-controlled entity, the Fourth Amendment‘s warrant requirement would be effectively evaded. The purpose of the FISA standard was to police such evasion, not to impose a criminal-law standard on foreign intelligence collection.[64] This is why, under FISA, an interception order may issue if the court finds there is probable cause to believe only that “(1) the target of the electronic surveillance is a foreign power or an agent of a foreign power …; (2) each of the facilities or places at which the electronic surveillance is directed is being used, or is about to be used, by a foreign power or an agent of a foreign power”; and certain procedures are followed to minimize inadvertent collection.[65] Professor Donohue gets this history and purpose all wrong.  She writes, “The point of having lowered [FISA] standards [compared to Title III] was to facilitate the collection of information about significant threats to national security.”[66] No, it wasn’t. Congress was not facilitating executive power; it was regulating a portion of that power severely and for the first time.

Professor Donohue is on far stronger ground in her criticism of the lowered standard for the production of business records under FISA. The statute was amended in 2015 so that the government was required merely to certify, not to demonstrate, to the FISC that the records sought were merely relevant to an authorized investigation “to protect against international terrorism or clandestine intelligence activities.” [67] In such a case, the magistrate may not inquire further and must enter the order. Professor Donohue asserts that the statute as it now stands is unconstitutional on its face, but that would be true only if persons had a constitutionally recognized privacy interest in data given to third parties. At present they do not. I would agree, however, that the relaxed standard has produced a British-style regime of seizure orders independent of the judiciary, and I would strengthen the standard to require the FISC judge to determine that the government has a factual basis for its assertion. [68]

The statute also creates too much room for evasion of the Title III warrant standard and may thus be unconstitutional as applied, even under Smith. Suppose the FBI wanted to compel the production of the business records of an American citizen who was not an agent of a foreign power but may have been colluding with a foreign agent in a different criminal scheme. The government could get a production order without having to obtain a Title III warrant. It would simply have to assert that evidence in the second scheme would somehow be useful in investigating the first one. That would be a dangerous infringement of constitutional protection against arbitrary executive power, and I hope it could not be defended merely by reference to the President’s Article II powers.

Technology Effects

The advent of fiber-optic technology long before the passage of the FAA had the unintended effect of expanding the FISA’s reach in irrational ways that are not widely understood. When FISA was enacted in 1978, telecommunications meant telephone and telegraph; there was no commercial Internet. Most long distance telecommunications employed a satellite link at some point in the transmission. That is, the electronic impulses representing a caller’s voice on a call between, say, New York and Hamburg, or between Hamburg and Tokyo, were sent via radio frequency up to a satellite and then down from a satellite before finishing their journey by copper wire. If NSA wanted to target that communication, it could and usually did collect it though the air, probably from an overseas location, so it was not regulated by FISA. Even if it was collected from a location inside the country, FISA did not regulate the collection as long as no U.S. Person was the target.[69] With the advent of commercial fiber-optic cable on international lines beginning in the 1988,[70] international call quality and reliability improved dramatically. But it also meant that the call between Hamburg and Tokyo was probably transmitted through a wire in the United States and thus became subject to FISA if collected in the United States, which was the easier and less risky way to do it. And given the U.S.-centric quality of the worldwide fiber-optic cable networks,[71] many other foreign-to-foreign communications also became subject to FISA. An unintended and perverse result was that a large volume of communications having nothing to do with FISA’s purpose was brought under the act. This was a major nuisance, and it meant that in a significant class of cases, FISA was not protecting the privacy of U.S. Persons. It was merely regulating the place of collection. The PAA and then the FAA fixed that anomaly.

A typical fiber-optic trunk cable carries a petabit of data per second.[72] The government does not “tap” these cables using alligator clips in the basement wire closet of an apartment building like in a 1940s movie. Interception occurs at a carrier’s switching station. If done by the police or FBI under a Title III warrant, the targeting must be precise because the government is forbidden from collecting anything outside the terms of the warrant. In the case of foreign intelligence, however, the situation is largely reversed. The President has the power to collect any communication likely to have foreign intelligence value but must take care not to collect U.S. Person communications except as authorized by FISA. This reversal is based on constitutional requirements, but it offends Professor Donohue. She asserts that FISA orders should be limited to “seizing or monitoring the content carried by a single telephone line, or to and from a particular computer address.[73] The Constitution does not require the President to take such a dainty approach to foreign intelligence collection, and Congress appears to believe, correctly in my view, that it has no power to impose such a requirement.

Access to Stored U.S. Person Data

 So much for electronic collection under section 702, but what about analysis of 702 data and the access to data that intelligence analysis and law enforcement both require? As Professor Donohue correctly notes, the database of collection under this section has become enormous. It contains the records of a publicly unknown but undoubtedly very large number of communications involving U.S. Persons located in the United States communicating with intelligence targets overseas. Our intelligence agencies and the FBI may search that database using U.S. Person selectors without restraint whenever they feel like it, even years after the collection occurred, even if they have lost interest in the overseas target. The government may not intentionally target that kind of communication for collection if the U.S. Person is the true target. But once the communication has been lawfully collected, the agency may “target” the U.S. Person when it searches the database by using that person’s name, phone number, email address, or other specific selector as a search term. This use of the term “target” to refer to database searches as opposed to collection is still unusual to intelligence agencies but is unlikely to remain so.

I share Professor Donohue’s objection to this legal state of affairs under section 702, and the objection will be more powerful if placed in a broader context. We have entered an era when the terms on which the government may search lawfully gathered information are becoming as important as the terms on which the information may be lawfully collected. We are used to regulating collection but not access to information. That is likely to change. The government’s access to vast quantities of information about U.S. Persons is growing dramatically. U.S. intelligence agencies already hold massive databases of information about Americans. They also have access to readily available commercial databases through a few keystrokes or through the purchase of proprietary databases. The data ocean is expanding as if propelled by a Digital Big Bang, and dealing with it requires automated analytic capabilities at previously unimaginable scale. Most of this data ocean is held by private companies, whose ability to gather it and skill in analyzing it exceed the government’s. The vast expansion of the private data market means that the government itself will gather relatively less data and purchase relatively more of it in open markets. Historically our laws and regulations have controlled who may collect intelligence, whose communications may be collected, how they may be collected, and what may be collected.[74] And once information about U.S. Persons has been lawfully collected, we also regulate how and to whom it may disseminated, but we have not regulated the conditions or frequency under which the collecting agency may access or analyze it. The protections afforded to U.S. Persons through collection rules seemed sufficient to protect our liberty. Section 702 is merely an example of this historical way of doing business. We are probably at the threshold of a new era. In the future, we are likely to be at least as concerned with the state’s ability to access information already collected, or available in the marketplace, as we have been with the conditions under which the state may collect it using its own resources.

Greater attention to data access as opposed to data collection will also be impelled by a change in intelligence agencies’ mission. Their task is no longer simply to acquire the communications of known foreign agents or to hunt moles in their own organizations, as was the case throughout the Cold War. Knowing who the foreign targets were was relatively easy. Stealing their communications was hard.[75]  That mission is now accompanied by a new one that has deep legal and public support, namely, to discover terrorist networks before they can wreak havoc. In the foreseeable future, this challenge will probably condition the intersection between intelligence gathering and citizens’ rights more than any other factor, yet it strangely finds no place in this book. In pursuit of terrorists, stealing the secrets is usually the less difficult task. The harder and more important part is knowing who they are, and that involves access under controlled conditions to communications data in bulk – both metadata and lawfully collected intercepts – and sifting them for information with intelligence value. Congress has properly begun to regulate that access, but the access must be available to carry out the mission, and a regulation that unreasonably impeded it would present a constitutional issue. To a significant degree, therefore, the challenge in intelligence collection has been turned on its head. Whether we like it or not, from now on more and more information will be in government hands or easily available to government. Increasingly the questions will be: When can government look at it? And how can we police abuses? 


 The subject of potential abuse brings us to the question of oversight, but this is a subject on which Professor Donohue, after raising it, has little to say. She treats us to a tantalizing observation by Stanford’s Professor Scott Sagan, whose work on nuclear weapons policy led him to conclude, in her words, that “the more protection one builds into a system, somewhat counterintuitively, the less secure it may become.” This is a brilliant insight of remarkably limited value here, since hardly anyone (including Professor Sagan[76]) would argue the converse: That the less protection one builds into the system of intelligence oversight, the more secure it is likely to become. Indeed Professor Donohue wants “more robust oversight.”[77] But she is vague on what that means. Her only concrete suggestion is to say it would be a good idea to have more people like her —amici curiae appointed by FISC — but this is what the USA Freedom Act actually did in 2015.

What Professor Sagan describes is a version of the shared responsibility trap, in which an actor with partial or redundant responsibility becomes lazy and inattentive in the belief that others have their eyes on the ball (“social shirking,” he calls it).[78] As the former inspector general of the National Security Agency during the STELLAR WIND period, that’s not how I saw intelligence oversight. My office had its hands full and was deeply involved not only in uncovering abuse after the fact (not usually involving intelligence collection, I might add) but also in preventing it. Different oversight mechanisms in different organizations are designed to accomplish different objectives – they are not redundant – and their critics usually pay insufficient attention to what the different parts are meant to do. It is unreasonable, say, to expect the House and Senate select committees on intelligence to monitor collection activities. Their responsibilities are strategic and general, not tactical and granular. In contrast, it would be reasonable for these budget authorizing committees to require that new collection capabilities be auditable to a standard agreeable to agency inspectors general, who are (or should be) able to monitor collection. But no oversight system will be perfect, and expecting perfection (usually with a handwringing reference to the unanswerable question, Who will watch the watchers?) leads only to the continual imposition of additional oversight mechanisms on top of one another, a tendency that expands the pool of unproductive employment opportunities at the expense of efficiency.

Expecting perfection also leads to what I call the Oversight Paradox: The closer one is to the activity being overseen, the more one will know about how it works, but the less one will be trusted; and the farther one is from the activity, the less one will know but the more one will be trusted. Since the Snowden disclosures, this paradox has been compounded by a different misunderstanding. Agency oversight officials are charged with preventing waste, fraud, and abuse, which includes illegality. But the bulk metadata collection program ordered by the President, personally approved by the attorney general under guidelines approved by the Justice Department, disclosed to the leaders of both houses of Congress and the chairmen and ranking members of both intelligence committees, and sanctioned in particular cases by more than a dozen federal judges was not unlawful. The problem was that the law was arguably secret — not to the Congress but to the public. No oversight system is built to deal with the failure of political judgment that led to that circumstance.[79]


Professor Donohue and I agree on a number of specific proposal and disagree profoundly on FISA’s rationale and constitutional limitations. The areas of agreement are important. First, the government should not be able to search the 702 database of lawfully collected U.S. Person information using U.S. Person selectors without a FISA order. Under the USA Freedom Act of 2015, we already impose a similar requirement before the government can access metadata records that are now held by the carriers rather than the intelligence agencies.[80]

Second, retention limitations should be considered for U.S. Person data held under section 702, though that kind of limitation may be difficult to apply in cases where the identity and citizenship or immigration status of the person or persons involved is doubtful.

Third, we should consider relieving FISA judges of some of their other workload as Article III federal district judges during their tenure on the FISC.[81]

Fourth, the standard for the production of tangible things under FISA should be strengthened. Congress should make it the same as the standard for the obtaining a surveillance order under the act. Both orders involve the same infringement on personal liberty, and there is no reason in principle to believe that one kind of infringement (acquisition of records of past communications) is less serious that the other (acquisition of current communications).

But then Professor Donohue and I part company because, if her basic diagnosis is constitutionally unsound, her favorite remedy could kill the patient. In her judgment, the fundamental problem with the FAA is that it muddled a supposedly clear distinction between foreign intelligence and criminal law. Consequently, she proposes that we build this dichotomy back into law and government operations. This is an appalling proposition, because if we have learned anything since 9/11, it is that the distinction was illusory. The barrier between criminality and foreign intelligence gathering was not done in by a nefarious ideological attack; it collapsed under the weight of the Twin Towers and our inability to track terrorists effectively.[82] Foreign intelligence investigations often, even usually, involve criminal acts,[83] and they often touch our own citizens and territory. Wishful thinking embellished with a different verbal formula will not make these facts go away. Professor Donohue’s refusal to acknowledge them then leads her to propose the re-erection of “The Wall”[84] — that is, the hermetical separation of criminal and intelligence investigators that had created a state of self-imposed blind man’s bluff between law enforcement and intelligence officials before 9/11, and the abolition of which was essential to our ability to maintain our security. Re-erecting that Wall would mean abolishing or neutering the Justice Department’s recently created National Security Division and re-imposing the voluntary ignorance and dysfunctionality by which the government’s left hand had no idea what its right was doing. Fortunately, the extreme undesirability of this proposal is matched by the extreme unlikelihood of its being adopted. Neither the country nor the courts are likely ever again to endorse self-imposed ignorance as a national policy.

Prior to the digital age, people did not typically carry a cache of sensitive personal information with them as they went about their day. Now it is the person who is not carrying a cell phone, with all that it contains, who is the exception. … Today, by contrast, it is no exaggeration to say that many of the more than 90% of American adults who own a cell phone keep on their person a digital record of nearly every aspect of their lives — from the mundane to the intimate.”).

[34] Professor Donohue uses the term “warrant” to refer both Title III and to FISA orders. Under FISA, surveillance orders are formally known simply as orders rather than warrants, apparently because the drafters of that statute wished to make clear that the President’s Article II power to collect foreign intelligence was not subject to the Fourth Amendment. I follow the statutory usage. The distinction can be significant. See Microsoft Corp. v. United States (In re Warrant to Search a Certain E-Mail Account) (Docket No. 14-2985, 2nd Cir., July 14, 2016).

[35] See, e.g., United States v. Graham, No. 12-4659, 2016 WL 3068018, at *1 (4th Cir. May 31, 2016) (en banc); United States v. Carpenter, 819 F.3d 880, 887 (6th Cir. 2016); In re Google Inc.

[36] Characterizing arguably overbroad orders as general warrants strikes me as wildly exaggerated, and it would no doubt surprise the judges of the FISC, who spend considerable effort crafting restraints they appear to find meaningful. She concedes, “There are some differences between the general warrants about which the Framers were concerned and those that mark the realm of foreign intelligence today.” Donohue, Future of Foreign Intelligence at 94. Among other things, FISA orders are limited in scope and must have a foreign intelligence nexus.

The AUMF is found at Pub. L. No. 107-40, § 2(a), 115 Stat. 224, 224 (Sept. 18, 2001) (reported as a note to 50 U.S.C.A. § 1541).

Under the old rule, NSA could freely collect that same communication if it captured it, say, from a satellite signal or a cable overseas, but it needed a FISA order if it captured the communication off a wire in the United States. Compare 50 U.S.C. § 1801(f)(2) (2006), with § 1801(f)(3) (2006). That requirement protected no one’s privacy. It merely regulated the place of interception.

She asserts there is now a direct relationship between the decline in Title III warrants and the increase in FISA orders. Donohue, Future of Foreign Intelligence at 30. Her data suggest she may be correct, but a deeper inquiry (and better data) would be required to prove the point. One would think that the changed nature of the threat to the nation had something to do with it.

[69] As originally passed in 1978, FISA defined “electronic surveillance” as “the acquisition by an electronic, mechanical, or other surveillance device of the contents of any wire or radio communication sent by or intended to be received by a particular, known United States person who is in the United States, if the contents are acquired by intentionally targeting that United States person, under circumstances in which a person has a reasonable expectation of privacy and a warrant would be required for law enforcement purposes.” Pub. L. 95-511 (Oct. 25, 1978), 92 Stat. 1785.

That enemy was pretty easy to find. Just hard to kill. This was different. This enemy was relatively easy to kill. He was just very, very hard to find.”).

Moreover, the central policy lesson is not that the U.S. government should reject all proposals to place more security forces at nuclear facilities, given the heightened terrorist threat after the September 11, 2001 attacks. Instead, the lesson is that we need to be smarter in the way we think about redundancy.”).

[81] Professor Donohue criticizes the political composition of the FISC as heavily Republican and therefore, in her view, anti-civil liberties. Apart from the dubious connection with political affiliation and libertarian views, she assumes that the number of Democrats on the court reflects the number of Democrats who have been offered the job. One Democratically appointed district judge of my acquaintance turned down the job — too much extra work, he said.
