A Miscarriage Of Justice: How Femtech Apps And Fog Data Evade Fourth Amendment Privacy Protections, Rachel Silver

Washington and Lee Journal of Civil Rights and Social Justice

After the fall of Roe v. Wade, states across the country have enacted extreme abortion bans. Anti-abortion states, emboldened by their new, unrestricted power to regulate women’s bodies, are only broadening the scope of abortion prosecutions. And modern technology provides law enforcement with unprecedented access to women’s most intimate information, including, for example, their menstrual cycle, weight, body temperature, sexual activity, mood, medications, and pregnancy details. Fourth Amendment law fails to protect this sensitive information stored on femtech apps from government searches. In a largely unregulated private market, femtech apps sell health and location data to third parties like Fog …

Administrative Regulation Of Programmatic Policing: Why "Leaders Of A Beautiful Struggle" Is Both Right And Wrong, Christopher Slobogin

Vanderbilt Law School Faculty Publications

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 constitutionaly 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 ofpeople. Because individualized suspicion does not exist with respect to any of these people's information, an individual-specific warrant …

The Empty Promise Of The Fourth Amendment In The Family Regulation System, Anna Arons

Faculty Publications

Each year, state agents search the homes of hundreds of thousands of families across the United States under the auspices of the family regulation system. Through these searches—required elements of investigations into allegations of child maltreatment in virtually every jurisdiction—state agents invade the home, the most protected space in Fourth Amendment jurisprudence. Accordingly, federal courts agree that the Fourth Amendment’s warrant requirement applies to family regulation home searches. But almost universally, the abstract recognition of Fourth Amendment protections runs up against a concrete expectation on the ground that state actors should have easy and expansive access to families’ homes. Legislatures …

Telephone Pole Cameras Under Fourth Amendment Law, Matthew Tokson

Utah Law Faculty Scholarship

In a series of recent cases, police officers have mounted sophisticated surveillance cameras on telephone poles and pointed them at the homes of people suspected of a crime. These cameras often operate for months or even years without judicial oversight, collecting vast quantities of video footage on suspects and their activities near the home. Pole camera surveillance raises important Fourth Amendment questions that have divided courts and puzzled scholars.

These questions are complicated because Fourth Amendment law is complicated. This is especially the case today as Fourth Amendment law is in a transitional phase, caught between older and newer paradigms …

Smart Meters As A Catalyst For Privacy Law, Matthew Tokson

Utah Law Faculty Scholarship

Smart utility meters raise several puzzling legal questions—and answering them can help point the way toward the future of Fourth Amendment and civil privacy law. This forum essay addresses two such issues: use restrictions on collected data, and voluntary data disclosure.

First, more than any other current technology, smart meters compel the development of use restrictions on collected data. The benefits of smart meters are potentially enormous, such that categorically prohibiting public utilities from collecting smart meter data is likely beyond the pale. Yet allowing law enforcement agents to obtain detailed or intimate data about the home without a warrant …

Social Norms In Fourth Amendment Law, Matthew Tokson, Ari Ezra Waldman

Michigan Law Review

Courts often look to existing social norms to resolve difficult questions in Fourth Amendment law. In theory, these norms can provide an objective basis for courts’ constitutional decisions, grounding Fourth Amendment law in familiar societal attitudes and beliefs. In reality, however, social norms can shift rapidly, are constantly being contested, and frequently reflect outmoded and discriminatory concepts. This Article draws on contemporary sociological literatures on norms and technology to reveal how courts’ reliance on norms leads to several identifiable errors in Fourth Amendment jurisprudence.

Courts assessing social norms generally adopt what we call the closure principle, or the idea that …

Adapting U.S. Electronic Surveillance Laws, Policies, And Practices To Reflect Impending Technological Developments, Eric Manpearl

Catholic University Law Review

Intelligence collection must always evolve to meet technological developments. While the collection programs under Section 702 of the FISA Amendments Act of 2008 have produced a great deal of valuable intelligence over the last decade, the United States must begin to think about foreseeable technological developments and strategically consider how to conduct signals intelligence (SIGINT) collection in the future.

This Article identifies four technological trends that could significantly impact the way the United States conducts SIGINT. Individuals now have access to sophisticated technologies that formerly only governments seemed capable of creating, and this decentralization of capabilities will likely only increase …

Limited Privacy In “Pings:” Why Law Enforcement’S Use Of Cell-Site Simulators Does Not Categorically Violate The Fourth Amendment, Lara M. Mcmahon

Washington and Lee Law Review

This Note proposes four factors courts should consider when asked to determine whether law enforcement’s use of a cell-site simulator constituted a Fourth Amendment search. The first asks courts to consider whether the cell-site simulator surveillance infringed on a constitutionally protected area, such as the home. The second asks courts to consider the duration of the cell-site simulator surveillance. The third asks courts to consider whether the cell-site simulator surveillance was conducted actively or passively. The fourth asks courts to focus on the nature and depth of the information obtained as a result of the cell-site simulator surveillance. If, after …

42nd Annual Foulston-Siefkin Lecture: The Next Wave Of Fourth Amendment Challenges After Carpenter, Matthew Tokson

Utah Law Faculty Scholarship

This is an edited and adapted version of the 42nd Annual Foulston Siefkin Lecture, delivered at Washburn University School of Law.

The lecture discusses the future of Fourth Amendment law following the Supreme Court’s enormously important decision in Carpenter v. United States. It analyzes Carpenter and argues that its detailed account of the privacy harms caused by government surveillance will be its most important legacy. Moreover, the Court’s emphasis on the risk of privacy harm is not a one-off or a sharp break from previous practice. Carpenter is consistent with a long line of Supreme Court decisions ignoring or reshaping …

Protecting Online Privacy In The Digital Age: Carpenter V. United States And The Fourth Amendment’S Third-Party Doctrine, Cristina Del Rosso, Carol M. Bast

Catholic University Journal of Law and Technology

The goal of this paper is to examine the future of the third-party doctrine with the proliferation of technology and the online data we are surrounded with daily, specifically after the Supreme Court’s decision in Carpenter v. United States. It is imperative that individuals do not forfeit their Constitutional guarantees for the benefit of living in a technologically advanced society. This requires an understanding of the modern-day functional equivalents of “papers” and “effects.”

Looking to the future, this paper contemplates solutions on how to move forward in this technology era by scrutinizing the relevancy of the third-party doctrine due …

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

Orin Kerr

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 …

The Fourth Amendment And New Technologies: Constitutional Myths And The Case For Caution, Orin S. Kerr

Orin Kerr

To one who values federalism, federal preemption of state law may significantly threaten the autonomy and core regulatory authority of The Supreme Court recently considered whether a1mmg an infrared thermal imaging device at a suspect's home can violate the Fourth Amendment. Kyllo v. United States announced a new and comprehensive rule: the government's warrantless use of senseenhancing technology that is "not in general use" violates the Fourth Amendment when it yields "details of the home that would previously have been unknowable without physical intrusion." Justice Scalia's majority opinion acknowledged that the Court's rule was not needed to resolve the case …

Cell Phones Are Orwell's Telescreen: The Need For Fourth Amendment Protection In Real-Time Cell Phone Location Information, Matthew Devoy Jones

Cleveland State Law Review

Courts are divided as to whether law enforcement can collect cell phone location information in real-time without a warrant under the Fourth Amendment. This Article argues that Carpenter v. United States requires a warrant under the Fourth Amendment prior to law enforcement’s collection of real-time cell phone location information. Courts that have required a warrant prior to the government’s collection of real-time cell phone location information have considered the length of surveillance. This should not be a factor. The growing prevalence and usage of cell phones and cell phone technology, the original intent of the Fourth Amendment, and United States …

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

Jason P. Nance

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 …

Customs, Immigration, And Rights: Constitutional Limits On Electronic Border Searches, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

The warrantless search of travelers’ electronic devices as they enter and exit the United States is rapidly increasing. While the Supreme Court has long recognized a border-search exception to the Fourth Amendment’s warrant requirement, it applies to only two interests: promoting the duty regime and preventing contraband from entering the country; and ensuring that individuals are legally admitted. The government’s recent use of the exception goes substantially beyond these matters. U.S. Customs and Border Protection (CBP) and Immigration and Customs Enforcement (ICE) are using it to search electronic devices, and at times the cloud, for evidence of any criminal activity, …

The Public Information Fallacy, Woodrow Hartzog

Faculty Scholarship

The concept of privacy in “public” information or acts is a perennial topic for debate. It has given privacy law fits. People struggle to reconcile the notion of protecting information that has been made public with traditional accounts of privacy. As a result, successfully labeling information as public often functions as a permission slip for surveillance and personal data practices. It has also given birth to a significant and persistent misconception — that public information is an established and objective concept.

In this article, I argue that the “no privacy in public” justification is misguided because nobody knows what “public” …

The Exclusionary Rule In The Age Of Blue Data, Andrew Ferguson

Articles in Law Reviews & Other Academic Journals

In Herring v. United States, Chief Justice John Roberts reframed the Supreme Court’s understanding of the exclusionary rule: “As laid out in our cases, the exclusionary rule serves to deter deliberate, reckless, or grossly negligent conduct, or in some circumstances recurring or systemic negligence.” The open question remains: how can defendants demonstrate sufficient recurring or systemic negligence to warrant exclusion? The Supreme Court has never answered the question, although the absence of systemic or recurring problems has figured prominently in two recent exclusionary rule decisions. Without the ability to document recurring failures, or patterns of police misconduct, courts can dismiss …

Fourth Amendment Textualism, Jeffrey Bellin

Michigan Law Review

The Fourth Amendment’s prohibition of “unreasonable searches” is one of the most storied constitutional commands. Yet after decades of Supreme Court jurisprudence, a coherent definition of the term “search” remains surprisingly elusive. Even the justices know they have a problem. Recent opinions only halfheartedly apply the controlling “reasonable expectation of privacy” test and its wildly unpopular cousin, “third-party doctrine,” with a few justices in open revolt.

These fissures hint at the Court’s openness to a new approach. Unfortunately, no viable alternatives appear on the horizon. The justices themselves offer little in the way of a replacement. And scholars’ proposals exhibit …

Psychosocial Analysis Of An Ethnography At The Cuyahoga County Public Defenders Office, Ernest M. Oleksy

The Downtown Review

Too often, social science majors become jaded with their field of study due to a misperception of the nature of many potential jobs which they are qualified for. Such discord is prevalent amongst undergraduates who strive for work in the criminal justice system. Hollywood misrepresentations become the archetypes of the aforementioned field, leaving out the necessity and ubiquity of accompanying desk work. Still other social science majors struggle to identify theoretical interpretations in praxis.

Fourth Amendment Constraints On The Technological Monitoring Of Convicted Sex Offenders, Ben A. Mcjunkin, J. J. Prescott

Articles

More than forty U.S. states currently track at least some of their convicted sex offenders using GPS devices. Many offenders will be monitored for life. The burdens and expense of living indefinitely under constant technological monitoring have been well documented, but most commentators have assumed that these burdens were of no constitutional moment because states have characterized such surveillance as ‘‘civil’’ in character—and courts have seemed to agree. In 2015, however, the Supreme Court decided in Grady v. North Carolina that attaching a GPS monitoring device to a person was a Fourth Amendment search, notwithstanding the ostensibly civil character of …

Cybersurveillance Intrusions And An Evolving Katz Privacy Test, Margaret Hu

Scholarly Articles

To contextualize why a new approach to the Fourth Amendment is essential, this Article describes two emerging cybersurveillance tools. The first Cybersurveillance tool, Geofeedia, has been deployed by state and local law enforcement. Geofeedia uses a process known as "geofencing" to draw a virtual barrier around a particular geographic region, and then identifies and tracks public social media posts within that region for predictive policing purposes. The second tool, Future Attribute Screening Technology (FAST), is under development by the United States Department of Homeland Security (DHS). FAST is another predictive policing tool that analyzes physiological and behavioral signals with the …

Bulk Biometric Metadata Collection, Margaret Hu

Scholarly Articles

Smart police body cameras and smart glasses worn by law enforcement increasingly reflect state-of-the-art surveillance technology, such as the integration of live-streaming video with facial recognition and artificial intelligence tools, including automated analytics. This Article explores how these emerging cybersurveillance technologies risk the potential for bulk biometric metadata collection. Such collection is likely to fall outside the scope of the types of bulk metadata collection protections regulated by the USA FREEDOM Act of 2015. The USA FREEDOM Act was intended to bring the practice of bulk telephony metadata collection conducted by the National Security Agency (“NSA”) under tighter regulation. In …

Game Of Drones: Rolling The Dice With Unmanned Aerial Vehicles And Privacy, Rebecca L. Scharf

Scholarly Works

This Article offers a practical three-part test for courts and law enforcement to utilize when faced with drone and privacy issues. Specifically addressing the question: how should courts analyze the Fourth Amendment’s protection against ‘unreasonable searches’ in the context of drones?

The Supreme Court’s Fourth Amendment jurisprudence produced an intricate framework to address issues arising out of the intersection of technology and privacy interests. In prominent decisions, including United States v. Katz, California v. Ciraolo, Kyllo v. United States, and most notably, United States v. Jones, the Court focused on whether the use of a single …

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 …

Sex & Surveillance: Gender, Privacy & The Sexualization Of Power In Prison, Teresa A. Miller

Teresa A. Miller

In prison, surveillance is power and power is sexualized. Sex and surveillance, therefore, are profoundly linked. Whereas numerous penal scholars from Bentham to Foucault have theorized the force inherent in the visual monitoring of prisoners, the sexualization of power and the relationship between sex and surveillance is more academically obscure. This article criticizes the failure of federal courts to consider the strong and complex relationship between sex and surveillance in analyzing the constitutionality of prison searches, specifically, cross-gender searches. The analysis proceeds in four parts. Part One introduces the issues posed by sex and surveillance. Part Two describes the sexually …

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 …

Policing Predictive Policing, Andrew Ferguson

Articles in Law Reviews & Other Academic 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 …
