In Leaders of a Beautiful Struggle v. Baltimore Police Department, the Fourth Circuit Court of Appeals held that Aerial Investigation Research (AIR), Baltimore’s aerial surveillance program, violated the Fourth Amendment because it was not authorized by a warrant. AIR was constitutionally problematic, but not for the reason given by the Fourth Circuit. AIR, like many other technologically-enhanced policing programs that rely on closed-circuit television (CCTV), automated license plate readers and the like, involves the collection and retention of information about huge numbers of people. Because individualized suspicion does not exist with respect to any of these people’s information, an individual-specific warrant requirement can never be met by such a program. When police engage in suspicionless searches and seizures of the type exemplified by AIR, a different regulatory approach is needed, one that provides the protection against arbitrariness that the warrant process affords but does not require findings that specific people have violated the law. This Article argues that this regulatory alternative can be derived from administrative law principles. The logic of administrative law dictates that legislatures and agency rulemaking must be involved any time a policing agency wants to establish a program that will intentionally affect sizeable numbers of concededly innocent people. If administrative law principles applied, programs like AIR would not be permitted unless a legislature has delegated appropriate authority to the relevant police agency, implemented regulations have survived notice-and-comment and hard look judicial review, and the agency carried out the program in an even-handed fashion that minimizes discretion. At the same time, contrary to the holding in Leaders of a Beautiful Stuggle, if these requirements are met, the Fourth Amendment—at least the part of it requiring warrants and probable cause—would be irrelevant.
Introduction
In Leaders of a Beautiful Struggle v. Baltimore Police Department, the Fourth Circuit Court of Appeals held that Aerial Investigation Research (AIR), Baltimore’s aerial surveillance program, violated the Fourth Amendment. Relying on the U.S. Supreme Court’s declarations in Carpenter v. United States and United States v. Jones that the Fourth Amendment governs both real-time and digital-record tracking, the Fourth Circuit correctly held that AIR’s constant recording of Baltimore’s pedestrian and car traffic constituted a “search” for Fourth Amendment purposes. But it erred in holding that such a program requires a warrant—a conclusion that, in effect, made AIR impossible as a legal matter. Because jurisdiction-wide systems like AIR do not purport to investigate a particular suspect, but rather aim only at gathering information that can later be used to carry out such investigations, they can never satisfy the Fourth Amendment warrant requirement, which regulates searches aimed at specific individuals.
There was another significant legal problem with AIR, however. In setting up the program, Baltimore and its police department failed to follow proper democratic and administrative processes. This Article argues that this oversight should have been the focus of the Fourth Circuit’s decision and should have been the death knell for the program. More generally, it argues that administrative law principles can and should fulfill the Fourth Amendment’s reasonableness requirement when the government wants to conduct suspicionless searches and seizures. While Carpenter, Jones, and other Fourth Amendment cases that address the constitutionality of searches aimed at specific individuals are inapposite in such situations, administrative law’s programmatic focus is ideally suited to govern data collection programs.
The aptly named Leaders of a Beautiful Struggle is a harbinger of cases to come as law enforcement continues to experiment with technologically-aided investigative techniques. In recent years, police departments and municipalities have avidly adopted surveillance systems using Automated License Plate Readers (ALPRs), closed-circuit television (CCTV), and facial recognition technology (FRT), and have also moved toward database analytics using “fusion centers” and private companies. Each of these programs involves the collection and retention of information about thousands, tens of thousands, or even hundreds of thousands of people. Because individualized suspicion does not exist at the time these law enforcement initiatives acquire information about people, imposition of an individual-specific warrant requirement makes little sense and, rigidly applied, would spell doom for all such programs, no matter how effective they are. A different regulatory approach is needed, one that provides the protection against arbitrariness that the warrant process affords but does not require findings that specific people have violated the law.
Because programmatic policing usually affects entire jurisdictions, this Article follows earlier work of mine in arguing that the regulatory regime in this setting should involve not just the courts, but significant engagement by the legislative and executive branches as well, as mediated through administrative law principles. In fact, the logic of administrative law requires agency rulemaking any time a policing agency proposes an investigative technique that will intentionally affect sizeable numbers of innocent people—a phenomenon that occurs not only with surveillance programs like AIR, but in connection with a wide array of physical searches and seizures such as health and safety inspections, checkpoints, and drug testing programs. These “panvasive” actions should not be permitted unless the requirements that typically govern informal rulemaking by all other agencies are met: a legislature must delegate appropriate authority to the relevant police agency, regulations must survive notice-and-comment and hard look judicial review, and the agency must carry out the program in an even-handed fashion that minimizes discretion. At the same time, contrary to the holding in Leaders of a Beautiful Struggle, if these administrative law requirements are followed, the Fourth Amendment—at least that part of it requiring warrants based on probable cause—should be irrelevant.
I. The AIR Program and Leaders of A Beautiful Struggle
On May 1, 2020, the City of Baltimore, with the help of a company called Persistent Surveillance Systems (PSS), initiated a six-month trial of an aerial surveillance program called AIR. AIR relied on cameras positioned on high-flying planes to monitor the city during the daytime. If a crime was caught on camera or it otherwise came to the attention of the police, the aerial recordings were used to trace the people and cars near the crime scene when it occurred both forward and backward in time to help identify who they were. Because any individuals picked up on the cameras appeared merely as blurry dots, facial features were not observable. But people could be identified by connecting them to certain residences and in various other ways. If identification occurred, subsequent interviews, interrogations, stops, and arrests were presumably governed by traditional Fourth and Fifth Amendment law.
Perhaps because of concerns about disparate racial impact, but also based on straightforward cost-benefit calculations, Baltimore ended its program in 2021. That response is, of course, the government’s prerogative. But in Leaders of a Beautiful Struggle, the Fourth Circuit Court of Appeals took it upon itself to hold that, had the police department not ended AIR, it would have found the program unconstitutional under the Fourth Amendment. In an eight to seven en banc opinion, the court analogized AIR’s surveillance of Baltimore’s populace both to Carpenter, which held that police investigating a bank robbery engaged in a search when they accessed multiple days of Carpenter’s cell-site location information from his common carrier, and Jones, which held that police investigating Jones for drug dealing engaged in a search when they tracked him for twenty-eight days using GPS signals. In light of these opinions, the majority reasoned, the day-to-day aerial surveillance that took place under AIR was a Fourth Amendment search that required a warrant. Because under well-established case law and the language of the Fourth Amendment itself, a warrant is impossible to obtain until a crime has occurred or a suspect has been identified, the Leaders of a Beautiful Struggle holding prohibited the pre-crime and citywide recordings on which AIR depended.
The major flaw in Leaders of a Beautiful Struggle is its conceptualization of the problem. The majority opinion described AIR as a program that was aimed at “capturing everyone’s movements outside during the daytime . . . .” Citing Carpenter and Jones, it then declared that “prolonged tracking that can reveal intimate details through habits and patterns . . . invades the reasonable expectation of privacy that individuals have in the whole of their movements and therefore requires a warrant.” But that type of reasoning applies only to long-term tracking of identified suspects, as occurred in Carpenter and Jones. The issue before the court was not the constitutionality of such suspect-driven or crime-driven searches but rather the constitutionality of a program that collects, in the absence of suspicion about any given individual, the information used for such searches.
This confusion between the legitimacy of the data collection and the legitimacy of its use permeated the majority’s opinion. The Fourth Circuit appeared to be particularly concerned that the program retained recordings of the movements of everyone caught on camera for forty-five days. But these recordings were not accessed unless a violent crime was caught on camera. If at that point, the police wanted to view recordings surrounding the time and place of the crime, judicial authorization—a warrant or court order—might well be required. But a warrant process aimed at determining whether there is cause to search for evidence against a specific person is ill-fitted to decisions about whether to create those records in the first instance and, if so, the length of time recordings are kept, the types of crimes they can be used to investigate, and other programmatic matters.
Another example of the majority’s confusion was its reaction to the district court’s finding that AIR images show only “a series of anonymous dots traversing a map of Baltimore.” In rebuking the lower court for relying on this fact, the Fourth Circuit correctly observed that the habitual behavior of those “dots” (such as starting and ending the day at home), when “analyzed with other available information, will often be enough for law enforcement to deduce the people behind the pixels.” But, again, that use of AIR was not before the court; had it been, the court could rightly have demanded a Fourth Amendment justification based on individualized suspicion.
In another passage, the majority—still conflating collection with use—asserted that “[t]he AIR program is like a [twenty-first] century general search, enabling the police to collect all movements, both innocent and suspected, without any burden to ‘articulate an adequate reason to search for specific items related to specific crimes.’” But in real time, AIR’s day-to-day collection of pixels was not seeking information about any specific items, crimes, or people. And its “general” nature made it a perfect candidate for jurisdiction-wide legislative regulation rather than case-specific judicial determinations.
That was the gist of Judge Wilkinson’s dissenting opinion. As he put it, “I have no problem if the AIR program is discontinued. I have a big problem, however, if this court and not the citizens of Baltimore are the ones to terminate it.” Judge Wilkinson noted that AIR had been established on an experimental basis, after obtaining endorsements from the governor of Maryland, the mayor of Baltimore, the Baltimore City Chamber of Commerce, and a number of other high profile groups, including community leaders in East and West Baltimore, the Greater Baltimore Committee (“the region’s premier organization of business and civic leaders”), the presidents of local universities, and religious leaders from the United Baptist Missionary Convention (representing 100 churches across the state). The reason for this wide-ranging support was summarized by the local head of Neighborhoods United: “We have to do something. The murders are doing a lot of disruption to our city, especially in the black population.” Pointing to this community support, Judge Wilkinson concluded: “The people most affected by a problem are denied by this court a say in ameliorating it.”
In short, the Fourth Circuit had no business ending the program on the grounds it did. At the same time, the Judiciary was not the only branch of government that overreached in connection with the AIR program. The Baltimore Police Department was also too dominant in the decisionmaking process. Despite the widespread official support for AIR, the Baltimore City Council never formally authorized it, even on a test basis, and the police department’s guidelines under which it operated were not subject to community input. The type of democratic process normally associated with the initiation of civilian, citywide programs was—at most—tangentially involved in vetting law enforcement’s use of AIR.
In critiquing the majority’s ruling, Judge Wilkinson quoted a statement from the concurring opinion of Justice Alito in Jones (joined by Justices Ginsburg, Breyer, and Kagan): “A legislative body is well situated to gauge changing public attitudes, to draw detailed lines, and to balance privacy and public safety in a comprehensive way.” That call for legislative involvement is particularly apt when it comes to programmatic searches and seizures like AIR, given the inapplicability of the traditional, judicially-oriented warrant process. Assuming so, there remains the crucial tasks of drawing the “detailed lines” to which Justice Alito refers and figuring out how to cajole legislatures and police agencies into promulgating them.
II. the Substantive Rules of Programmatic Policing
There are two broad issues raised by programmatic searches and seizures. The first is whether a particular program should be authorized. For what purposes may a municipality, state, or federal government establish panvasive dragnets like AIR, fusion centers, or random inspection regimes, and what types of information may these policing efforts collect? Assuming the program is authorized, the second issue is how long the information it obtains may be retained and under what conditions. May the data collected be maintained indefinitely or should it be destroyed after a finite period, and how can the accuracy and security of the data be assured?
A helpful conceptualization of how data collection and retention might be regulated comes from the American Law Institute (ALI), which recently completed its Principles of Policing Project after six years of deliberation. The fourteen chapters of the Principles—which cover every aspect of the policing endeavor—were officially adopted by the full membership of the ALI in May 2022, after vetting by both an advisory committee (composed of judges and lawyers who work in the criminal justice system, police and advocacy organizations from both the left and right) and the ALI Council (composed of a select group of the full ALI membership). As an associate reporter for the project, I was principally responsible for two of the Principles’ chapters: “Policing in the Absence of Individualized Suspicion” and “Policing Databases.” Respectively, these two chapters provide principles that could govern the collection and retention issues raised by programmatic searches.
“Policing in the Absence of Individualized Suspicion” is defined by the ALI Principles as policing “conducted in the absence of cause to believe that the particular individual, place, or item subject to [the policing action] is involved in unlawful conduct . . . .” It should be clear from previous discussion that surveillance programs like AIR fit within this definition; because they are panvasive, they are designed to obtain information before any individualized suspicion develops. In this way, they are like various types of physical search programs—such as checkpoints, health and safety inspections, and drug-testing programs—that operate in the absence of individual suspicion.
The ALI chapter on this type of policing provides that “[l]egislatures and agencies should authorize suspicionless policing activities only when there is a sound basis for believing that they will accomplish an important law-enforcement or regulatory objective, and when achieving that objective outweighs their infringement on individual interests such as privacy, dignity, property, and liberty.” If a suspicionless program is authorized, written policies should identify, among other things, “(a) the specific harm sought to be detected or prevented; (b) the permissible scope of the suspicionless policing activity; [and] (c) the persons, entities, or activities subject to the policing activity.” Additionally, the Principles state that any suspicionless policing activity so approved “should be conducted in a manner that ensures agency discretion is guided by neutral criteria that are applied evenhandedly and developed in advance,” which must be accomplished by applying the procedure to every person within the target group, “a subset of that group that is selected on a random or neutral basis,” or “a subset of that group that there is a sound basis for believing is more likely to be engaged in unlawful conduct or pose a greater risk of harm than the rest of the target group.” There are several more detailed principles in the chapter, but these three capture its gist: suspicionless searches and seizures should only occur when (1) there is a strong rational basis for the program after considering its impact on collective and individual interests; (2) policies explicitly identify its purpose and scope; and (3) the program is applied in a neutral, even-handed fashion.
The primary rationale for these principles is straightforward: “In the absence of warrants and individualized suspicion, it is essential that there be alternative mechanisms in place to ensure that searches and seizures and other policing activities are justified, are not directed at individuals or groups in an arbitrary or discriminatory fashion, and are limited in scope consistent with their justification.” The “sound basis” requirement for surveillance legislation is admittedly vague, but necessarily so. As Justice Alito’s comments in Jones suggest, the initiation of panvasive programs calls for the kind of multifactor judgment that is best made initially by legislatures. The requirement that the purpose and scope of the program be explicitly identified ensures that these matters receive due deliberation by the appropriate decisionmaking bodies and that the policing agency has sufficient direction. The neutral criteria and even-handed application requirements minimize discretion and increase the likelihood that the program will be viewed by the public as both more legitimate and less intrusive (think, for instance, of TSA checkpoints at airports). These latter two requirements also make it likely that the program will affect those with political power, which acts as a brake on overly aggressive programs. As Justice Jackson stated in another context: “[T]here is no more effective practical guaranty against arbitrary and unreasonable government than to require that the principles of law which officials would impose upon a minority must be imposed generally.”
The gist of the ALI chapter on policing databases can also be succinctly stated. It provides that “[a] policing database [defined to include databases that might be generated by AIR, CCTV, fusion centers, and the like] should be created only if necessary to facilitate a legitimate policing objective” and continues:
Any policing database that contains information about identified or identifiable individuals should be governed by written policy or policies that specify: (1) the purpose of the data collection, including the criteria for inclusion in the database; (2) the scope of data to be collected, including the types of individuals, locations, or records that will be the focus of the database; and (3) the limits on data retention, the procedures for ensuring the accuracy and security of the data, the circumstances under which the data can be accessed, and mechanisms for ensuring compliance with these rules.
The first two principles overlap with the provisions in the chapter on suspicionless policing requiring delineation of the purpose and scope of such search and seizure programs. The third principle is given more detailed treatment in the database chapter’s subsequent provisions, which focus on:
- purging databases of irrelevant information by requiring, whenever feasible, destruction of files after a finite time period;
- assuring data accuracy through standardized procedures for entering data; training and supervision of those who enter data; periodic audits for accuracy; and a procedure that allows correction of erroneous entries by data subjects (who are entitled to notification of their inclusion in a database anytime it is the basis for an “adverse action”);
- maintaining security through limiting access to those officers who are specifically authorized access through court order or otherwise; identifying an officer responsible for security; and monitoring the database for breaches; and
- assuring accountability through an unalterable record of every instance of access (detailing when it occurred, by whom, and for what purpose, as well as by what method, e.g., via algorithm); and by making available to the public “statistics about the purposes and use of policing databases, the numbers of people in each database, and the extent to which the databases have been accessed, including any violations of access rules.”
These two sets of ALI principles, which are consistent with suggestions made by other entities and scholars, provide guardrails for thinking about data collection and retention. But they are aspirational and expressed at a high level of generality. How can legislatures and policing agencies be pushed toward adopting something like them and then fleshing out the details in connection with specific policing programs? Supreme Court case law has provided very little impetus in this direction, and legislative inertia or resistance has led, at best, to piecemeal statutory regulation. After documenting those assertions, the remainder of this Article explains why another source of rules—administrative law—must play a central role in this regulatory framework. If the well-established administrative law principles that govern virtually all other government agencies are made applicable to policing agencies as well, they can force the legislative and executive branches to produce reasonable regulations of search and seizure programs.
III. Current Regulation of Programmatic Policing
Fourth Amendment jurisprudence to date has largely ignored both the data collection and data retention issues. While legislatures have been more active on these issues, some types of search and seizure programs today are not subject to any statutory constraints and those that are often only loosely so.
Contrary to the Fourth Circuit’s assertion in Leaders of a Beautiful Struggle, the Supreme Court’s decisions Carpenter and Jones provide no help on the issue of when a surveillance program or other search and seizure programs may be authorized; as explained earlier, these cases involved suspect-driven searches, not panvasive ones. Of course, Carpenter and Jones do not exhaust the Fourth Amendment’s potential. As David Gray has argued, for instance, the Fourth Amendment’s language guaranteeing “the right of the people” to be secure from unreasonable searches and seizures could form the basis for protecting the collective interests of citizens against indiscriminate, arbitrary surveillance, and voracious and insecure databases. Neil Richards has contended that the First Amendment’s protection against chilling speech and assembly could fulfil much the same function. While no Supreme Court case has endorsed these precise themes, scattered dicta hint that there may be constitutional limits on “data greed.” In United States v. Knotts, after holding that short-term tracking of an individual was not a Fourth Amendment search, the Court suggested that “different constitutional principles” might apply to “twenty-four hour surveillance of any citizen of this country . . . without judicial knowledge or supervision.” And in Whalen v. Roe, it recognized “the threat to privacy implicit in the accumulation of vast amounts of personal information in computerized data banks or other massive government files.” It remains the case, however, that the Court has yet to put any meat on these bones or even identify the specific constitutional provision that might do so.
The one existing Fourth Amendment doctrine that could potentially lead to something more comes from a convoluted series of Supreme Court decisions that govern situations involving “exceptional circumstances in which special needs, beyond the normal need for law enforcement, make the warrant and probable-cause requirements impracticable.” In some of these so-called “special needs” cases, particularly those involving inspections and checkpoints conducted in the absence of individualized suspicion, the Court has appeared to endorse something akin to the ALI Principles’ requirements that search and seizure programs have a rational basis and defined scope and be governed by a neutral plan that is administered even-handedly.
For instance, in Donovan v. Dewey, after noting the many dangers associated with operating coal mines, the Court upheld a warrantless mine inspection program because the statute governing the program:
[R]equires inspection of all mines and specifically defines the frequency of inspection. . . . [T]he standards with which a mine operator is required to comply are all specifically set forth in the [Mine Safety] Act or in . . . the Code of Federal Regulations. . . . [R]ather than leaving the frequency and purpose of inspections to the unchecked discretion of Government officers, the Act establishes a predictable and guided federal regulatory presence.
