Body Cameras And The Path To Redeem Privacy Law, Woodrow Hartzog

Faculty Scholarship

From a privacy perspective, the movement towards police body cameras seems ominous. The prospect of a surveillance device capturing massive amounts of data concerning people’s most vulnerable moments is daunting. These concerns are compounded by the fact that there is little consensus and few hard rules on how and for whom these systems should be built and used. But in many ways, this blank slate is a gift. Law and policy makers are not burdened by the weight of rules and technologies created in a different time for a different purpose. These surveillance and data technologies will be modern. Many …

Biometric Cyberintelligence And The Posse Comitatus Act, Margaret Hu

Scholarly Articles

This Article addresses the rapid growth of what the military and the intelligence community refer to as “biometric-enabled intelligence.” This newly emerging intelligence tool is reliant upon biometric databases—for example, digitalized storage of scanned fingerprints and irises, digital photographs for facial recognition technology, and DNA. This Article introduces the term “biometric cyberintelligence” to more accurately describe the manner in which this new tool is dependent upon cybersurveillance and big data’s massintegrative systems.

This Article argues that the Posse Comitatus Act of 1878, designed to limit the deployment of federal military resources in the service of domestic policies, will be difficult …

Student Surveillance, Racial Inequalities, And Implicit Racial Bias, Jason P. Nance

UF Law Faculty Publications

In the wake of high-profile incidents of school violence, school officials have increased their reliance on a host of surveillance measures to maintain order and control in their schools. Paradoxically, such practices can foster hostile environments that may lead to even more disorder and dysfunction. These practices may also contribute to the so-called “school-to-prison pipeline” by pushing more students out of school and into the juvenile justice system. However, not all students experience the same level of surveillance. This Article presents data on school surveillance practices, including an original empirical analysis of restricted data recently released by the U.S. Department …

Policing Predictive Policing, Andrew Ferguson

Scholarly Articles in Law Reviews & Journals

Predictive policing is sweeping the nation, promising the holy grail of policing – preventing crime before it happens. Police have embraced predictive analytics and data-driven metrics to improve law enforcement tactics, practice, and strategy. Predictive “hot spots” become targets for intensive police surveillance. Targeted “hot people” become suspects. In big cities and small towns, data-based predictions drive police patrol schedules. Risk assessment algorithms target suspicious individuals. Increased data collection fuels a growing feedback loop requiring more robust data crunching systems.All of these predictive innovations share one thing in common: a belief that crime can be understood by identifying and analyzing …

Knowledge And Fourth Amendment Privacy, Matthew Tokson

Northwestern University Law Review

This Article examines the central role that knowledge plays in determining the Fourth Amendment’s scope. What people know about surveillance practices or new technologies often shapes the “reasonable expectations of privacy” that define the Fourth Amendment’s boundaries. From early decisions dealing with automobile searches to recent cases involving advanced information technologies, courts have relied on assessments of knowledge in a wide variety of Fourth Amendment contexts. Yet the analysis of knowledge in Fourth Amendment law is rarely if ever studied on its own.

This Article fills that gap. It starts by identifying the characteristics of Fourth Amendment knowledge. It finds, …

Tightening The Ooda Loop: Police Militarization, Race, And Algorithmic Surveillance, Jeffrey L. Vagle

Michigan Journal of Race and Law

This Article examines how military automated surveillance and intelligence systems and techniques, when used by civilian police departments to enhance predictive policing programs, have reinforced racial bias in policing. I will focus on two facets of this problem. First, I investigate the role played by advanced military technologies and methods within civilian police departments. These approaches have enabled a new focus on deterrence and crime prevention by creating a system of structural surveillance where decision support relies increasingly upon algorithms and automated data analysis tools and automates de facto penalization and containment based on race. Second, I will explore these …

Never Alone: Why The Inevitable Influx Of Drones Necessitates A New Fourth Amendment Standard That Adequately Protects Reasonable Expectations Of Privacy, Paul Burgin

University of Baltimore Law Review

In June 2011, North Dakota cattle rancher Rodney Brossart became the first American to be arrested with the aid of a drone (Unmanned Aircraft System(s) or UAS) operated by law enforcement. Six cows found their way onto Brossart's property, and he refused to turn them over to law enforcement officials. Brossart and a few family members chased police officers off of his property at gunpoint, and police later returned with a warrant and SWAT team. A sixteen-hour standoff ensued until police called in the assistance of a UAS to pinpoint Brossart's exact location. Shortly thereafter, SWAT officers rushed in, tased, …

The Internet Of Things And The Fourth Amendment Of Effects, Andrew Ferguson

Scholarly Articles in Law Reviews & Journals

By 2020 there will be billions of “things” connected through the “Internet of Things.” These smart devices built within our homes, cars, smartphones, clothing, and accessories present new possibilities for technological surveillance for law enforcement. This network of smart devices also poses a new challenge for a Fourth Amendment built around “effects.” The constitutional language protecting “persons, houses, papers, and effects” from unreasonable searches and seizures must confront this change. This article addresses how a Fourth Amendment built on old-fashioned “effects” can address a new world when things are no longer just inactive, static objects, but objects that create and …

Keeping Pace: The U.S. Supreme Court And Evolving Technology, Brian Thomas

Politics Summer Fellows

Contemporary mainstream discussions of the Supreme Court are often qualified with the warning that the nine justices are out of touch with everyday American life, especially when it comes to the newest and most popular technologies. For instance, during oral argument for City of Ontario v. Quon, a 2010 case that dealt with sexting on government-issued devices, Chief Justice John Roberts famously asked what the difference was “between email and a pager,” and Justice Antonin Scalia wondered if the “spicy little conversations” held via text message could be printed and distributed. While these comments have garnered a great deal of …

No More Shortcuts: Protect Cell Site Location Data With A Warrant Requirement, Lauren E. Babst

Michigan Telecommunications & Technology Law Review

In modern society, the cell phone has become a virtual extension of most Americans, managing all kinds of personal and business matters. Modern cell tower technology allows cell service providers to accumulate a wealth of individuals’ location information while they use their cell phones, and such data is available for law enforcement to obtain without a warrant. This is problematic under the Fourth Amendment, which protects reasonable expectations of privacy. Under the Katz two-prong test, (1) individuals have an actual, subjective expectation of privacy in their cell site location data, and (2) society is prepared to acknowledge that expectation as …

The Un-Territoriality Of Data, Jennifer Daskal

Scholarly Articles in Law Reviews & Journals

Territoriality looms large in our jurisprudence, particularly as it relates to the government’s authority to search and seize. Fourth Amendment rights turn on whether the search or seizure takes place territorially or extraterritorially; the government’s surveillance authorities depend on whether the target is located within the United States or without; and courts’ warrant jurisdiction extends, with limited exceptions, only to the borders’ edge. Yet the rise of electronic data challenges territoriality at its core. Territoriality, after all, depends on the ability to define the relevant “here” and “there,” and it presumes that the “here” and “there” have normative significance. The …

Widening The Aperture On Fourth Amendment Interests: A Comment On Orin Kerr's The Fourth Amendment And The Global Internet, David G. Delaney

Articles by Maurer Faculty

Physical-world law may not be suitable for cyberspace. For example, the Supreme Court's "sufficient connection" test in U.S. v. Verdugo-Urquidez (1990) is inconsistent with the century-long trend for courts to find greater constitutional protections for those subject to U.S. jurisdiction outside the United States. Courts must maintain flexibility to conceive of a Fourth Amendment that does not depend exclusively on territory to fulfill its twin aims of ordering government and enabling redress of liberty infringements. Federal and state courts and legislatures addressing searches, seizures, and surveillance in cyberspace should seek simple rules that can easily adapt as cyberspace and government …

The Fourth Amendment And Surveillance In A Digital World, Arthur Leavens

Faculty Scholarship

Technology has transformed government surveillance and opened traditionally private information to official scrutiny. The current privacy-based approach to the Fourth Amendment is unable to cope with the changes. This Article offers a solution to the problems that technological surveillance techniques present. Starting with the introduction of the approach in Katz, the Article reviews the development of privacy-based approach. It then looks at three 21st century Supreme Court cases that grappled with applying the Katz test to advanced technological surveillance techniques: Kyllo, Quon, and Jones. These cases demonstrate the problems that the privacy-based approach creates and the …

Beyond The Fourth Amendment: Additional Constitutional Guarantees That Mass Surveillance Violates, Nadine Strossen

Articles & Chapters

The ongoing dragnet communications surveillance programs raise multiple statutory and constitutional problems. Each problem alone, and even more so the whole combination, provides a serious ground at least for vastly curbing such programs, if not ending them. This Article reviews constitutional challenges to these programs to evaluate the likely success of current and future litigants.

Beyond The Schoolhouse Gates: The Unprecedented Expansion Of School Surveillance Authority Under Cyberbulling Laws, Emily Suski

Faculty Publications

For several years, states have grappled with the problem of cyberbullying and its sometimes devastating effects. Because cyberbullying often occurs between students, most states have understandably looked to schools to help address the problem. To that end, schools in forty-six states have the authority to intervene when students engage in cyberbullying. This solution seems all to the good unless a close examination of the cyberbullying laws and their implications is made. This Article explores some of the problematic implications of the cyberbullying laws. More specifically, it focuses on how the cyberbullying laws allow schools unprecedented surveillance authority over students. This …

Cause To Believe What? The Importance Of Defining A Search's Object--Or, How The Aba Would Analyze The Nsa Metadata Surveillance Program, Christopher Slobogin

Vanderbilt Law School Faculty Publications

Courts and scholars have devoted considerable attention to the definition of probable cause and reasonable suspicion. Since the demise of the mere evidence rule in the 1960s, however, they have rarely examined how these central Fourth Amendment concepts interact with the object of the search. That is unfortunate, because this interaction can have significant consequences. For instance, probable cause to believe that a search might lead to evidence of wrongdoing triggers a very different inquiry than probable cause to believe that a search will produce evidence of criminal activity. The failure to address the constraints that should be imposed on …

Our Records Panopticon And The American Bar Association Standards For Criminal Justice, Stephen E. Henderson

Faculty Articles

"Secrets are lies. Sharing is caring. Privacy is theft." So concludes the main character in Dave Egger’s novel The Circle, in which a single company that unites Google, Facebook, and Twitter – and on steroids – has the ambition not only to know, but also to share, all of the world's information. It is telling that a current dystopian novel features not the government in the first instance, but instead a private third party that, through no act of overt coercion, knows so much about us. This is indeed the greatest risk to privacy in our day, both the unprecedented …

Bulk Metadata Collection: Statutory And Constitutional Considerations, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

The National Security Agency’s bulk collection of telephony metadata runs contrary to Congress’s intent in enacting the 1978 Foreign Intelligence Surveillance Act. The program also violates the statute in three ways: the requirement that records sought be “relevant to an authorized investigation;” the requirement that information could be obtained via subpoena duces tecum; and the steps required for use of pen registers and trap and trace devices. Additionally, the program gives rise to serious constitutional concerns. Efforts by the government to save the program on grounds of third party doctrine are unpersuasive in light of the unique circumstances of …

A Shattered Looking Glass: The Pitfalls And Potential Of The Mosaic Theory Of Fourth Amendment Privacy, David Gray, Danielle K. Citron

Faculty Scholarship

On January 23, 2012, the Supreme Court issued a landmark non-decision in United States v. Jones. In that case, officers used a GPS-enabled device to track a suspect’s public movements for four weeks, amassing a considerable amount of data in the process. Although ultimately resolved on narrow grounds, five Justices joined concurring opinions in Jones expressing sympathy for some version of the “mosaic theory” of Fourth Amendment privacy. This theory holds that we maintain reasonable expectations of privacy in certain quantities of information even if we do not have such expectations in the constituent parts. This Article examines and explores …

Preserving Privacy In A Digital Age: Lessons Of Comparative Constitutionalism, David Cole

Georgetown Law Faculty Publications and Other Works

In the modern age, we increasingly live our lives through, and accompanied by, digital media. Virtually every transaction or communication that uses such media, as well as every move of mobile phone owners, is recorded. Computers are able to store, transmit, and analyze the data as never before, drawing on multiple sources to construct an intimate picture of our interests, contacts, travels and desires. Private data-mining services, most often used for commercial advertising purposes, can determine: what we read, listen to, and look at; where we travel to, shop, and dine; and with whom we speak or associate. Meanwhile, social …

Passing The Sniff Test: Police Dogs As Surveillance Technology, Irus Braverman

Journal Articles

In October 2012, the Supreme Court of the United States will review the case of Florida v. Jardines, which revolves around the constitutionality of police canine Franky’s sniff outside a private residence. Essentially, the Court will need to decide whether or not the sniff constitutes a “search” for Fourth Amendment purposes. This Article presents a review of the often-contradictory case law that exists on this question to suggest that underlying the various cases is the Courts’ assumption of a juxtaposed relationship between nature and technology. Where dog sniffs are perceived as a technology, the courts have been inclined to also …

The Mosaic Theory Of The Fourth Amendment, Orin S. Kerr

Michigan Law Review

In the Supreme Court's recent decision on GPS surveillance, United States v. Jones, five justices authored or joined concurring opinions that applied a new approach to interpreting Fourth Amendment protection. Before Jones, Fourth Amendment decisions had always evaluated each step of an investigation individually. Jones introduced what we might call a "mosaic theory" of the Fourth Amendment, by which courts evaluate a collective sequence of government activity as an aggregated whole to consider whether the sequence amounts to a search. This Article considers the implications of a mosaic theory of the Fourth Amendment. It explores the choices and puzzles that …
