Video Analytics And Fourth Amendment Vision, Andrew Guthrie Ferguson

Articles in Law Reviews & Other Academic Journals

What does the Fourth Amendment have to say about video analytics running on citywide camera systems? Video analytics (also known as computer vision) involves hardware and software in cameras that turns video surveillance streams into useful data, identifying, categorizing, matching, and alerting police about objects, people, and incidents. Video analytics can identify objects (e.g., hat, backpack, person, car) and track that person or thing back in time and through the streets using video surveillance footage. For police officers conducting virtual patrols or retrospective investigations, video analytics lets police scan thousands of linked cameras for suspicious behavior or a particular suspect, …

Police Shootings After Torres V. Madrid: Suspects Eluding Capture Are Seized Under Fourth Amendment, Travis R. Thickstun

The Scholar: St. Mary's Law Review on Race and Social Justice

In Torres v. Madrid, the Supreme Court held that the application of physical force to the body of a person with intent to restrain is a seizure even if the person does not submit and is not subdued. Because this new rule brings even the slightest touches within the Fourth Amendment’s protections against unreasonable searches and seizures, it allows more claims against police officers for violations of the Fourth Amendment’s prohibition on unreasonable searches and seizures.

Until the Torres decision though, only when someone shot by police was actually taken into custody could that person sue the police officers …

Going Cashless: Privacy Implications For Gun Control In A Digital Economy, Liza Goldenberg

The Journal of Business, Entrepreneurship & the Law

This paper will examine how, given the United States’ shift toward a cashless economy, the country’s top credit-card companies’ potential decision to implement a new merchant code for firearm-related transactions as a method of gun control will backfire, jeopardizing consumer privacy and leading to unregulated transactions through cryptocurrencies. Since the majority of gun violence stems from firearm transactions not involving credit cards, credit-card companies should abandon the new merchant code that dissuades Americans from exercising their fundamental rights. The American economy should focus on slowing the shift toward a digital economy so that federal and state governments can implement legislation …

Computationally Assessing Suspicion, Wesley M. Oliver

Law Faculty Publications

Law enforcement officers performing drug interdiction on interstate highways have to decide nearly every day whether there is reasonable suspicion to detain motorists until a trained dog can sniff for the presence of drugs. The officers’ assessments are often wrong, however, and lead to unnecessary detentions of innocent persons and the suppression of drugs found on guilty ones. We propose a computational method of evaluating suspicion in these encounters and offer experimental results from early efforts demonstrating its feasibility. With the assistance of large language and predictive machine learning models, it appears that judges, advocates, and even police officers could …

The Post-Dobbs Reality: Privacy Expectations For Period-Tracking Apps In Criminal Abortion Prosecutions, Sophie L. Nelson

Pepperdine Law Review

The Supreme Court’s decision to overturn Roe v. Wade and Planned Parenthood v. Casey in June 2022 was met with waves of both support and criticism throughout the United States. Several states immediately implemented or began drafting trigger laws that criminalize seeking and providing an abortion. These laws prompted several period-tracking app companies to encrypt their users’ data to make it more difficult for the government to access period- and pregnancy-related information for criminal investigations. This Comment explores whether the Fourth Amendment and U.S. privacy statutes protect users of period-tracking apps from government surveillance. More specifically, this Comment argues that …

Pretrial Commitment And The Fourth Amendment, Laurent Sacharoff

Notre Dame Law Review

Today, the Fourth Amendment Warrant Clause governs arrest warrants and search warrants only. But in the founding era, the Warrant Clause governed a third type of warrant: the “warrant of commitment.” Judges issued these warrants to jail defendants pending trial. This Article argues that the Fourth Amendment Warrant Clause, with its oath and probable cause standard, should be understood today to apply to this third type of warrant. That means the Warrant Clause would govern any initial appearance where a judge first commits a defendant—a process that currently falls far short of fulfilling its constitutional and historical function. History supports …

The Unconstitutional Conditions Vacuum In Criminal Procedure, Kay L. Levine, Jonathan R. Nash, Robert A. Schapiro

Faculty Articles

For more than a century, the Supreme Court has applied the unconstitutional conditions doctrine in many contexts, scrutinizing government efforts to condition the tradeoff of rights for benefits with regard to speech, funding, and takings, among others. The Court has declined, however, to invoke the doctrine in the area of criminal procedure, where people accused of crime are often asked to—and often do—surrender their constitutional rights under the Fourth, Fifth, and Sixth Amendments in return for some benefit. Despite its insistence that the unconstitutional conditions doctrine applies broadly across the Bill of Rights, the Court’s jurisprudence demonstrates that the doctrine …

The Modern Border: The Government Can Search . . . Anything?, Abigail Nusbaum

FIU Law Review

The evolution of modern technology has introduced new obstacles in interpreting the Fourth Amendment’s application to searches of peoples’ effects. Specifically, the longstanding exception to the Fourth Amendment permitting searches at the international border in the absence of probable cause does not so neatly apply to forensic searches of cell phones. Consequently, a circuit split has emerged on two aspects of the issue: the scope of the border exception and the requisite level of suspicion within that exception. The Supreme Court should find that forensic cell phone searches at the international border implicate Fourth Amendment privacy interests, requiring the border …

Digital Rummaging, Andrew Guthrie Ferguson

Articles in Law Reviews & Other Academic Journals

The digital world encodes our lives with incriminating clues. How you travel, live, love, and shop are tracked through growing surveillance technologies. Police have recognized this reality and are actively exploiting new surveillance tools for investigative purposes.

The Fourth Amendment—the constitutional protection meant to limit police search powers—has not kept up with the privacy and security threats of these new digital technologies. Current doctrine has remained stymied by legal tests asking all the wrong questions about “reasonable expectations of privacy” and “trespass” searches. While the Supreme Court has acknowledged that “digital is different,” it has not yet provided a coherent …

Constitutionalizing Racism, Jonathan Feingold

Faculty Scholarship

Unreasonable is Devon Carbado at his best. Through accessible prose, carefully crafted hypotheticals, effective visualizations, and some cross-examination (for the reader), Carbado reintroduces us to the Fourth Amendment. In arresting detail, Unreasonable" exposes how the Supreme Court has turned the Fourth Amendment against “the people”—and specifically, against people racialized as Black. Part of the “Bill of Rights,” the Fourth Amendment was adopted to protect “the right of the people” from police overreach. Yet over the past half-century, the Supreme Court has systematically repositioned the Fourth Amendment as a weapon of police power. Or as Carbado argues: whereas many assume …

Reasonable In Time, Unreasonable In Scope: Maximizing Fourth Amendment Protections Under Rodriguez V. United States, Thomas Heiden

Washington Law Review

In Rodriguez v. United States, the Supreme Court held that a law enforcement officer may not conduct a drug dog sniff after the completion of a routine traffic stop because doing so extends the stop without reasonable suspicion in violation of the Fourth Amendment’s prohibition on unreasonable seizures. Tracing the background of Rodriguez from the Supreme Court’s landmark decision in Terry v. Ohio, this Comment argues that Rodriguez is best understood as a reaction to the continued erosion of Fourth Amendment protections in the investigative stop context. Based on that understanding, this Comment argues for a strict reading of Rodriguez, …

Private Police Regulation And The Exclusionary Remedy: How Washington Can Eliminate The Public/Private Distinction, Jared Rothenberg

Washington Law Review

Private security forces such as campus police, security guards, loss prevention officers, and the like are not state actors covered by the Fourth Amendment’s prohibition against unreasonable searches and seizures nor the Fifth Amendment’s Miranda protections. As members of the umbrella category of “private police,” these private law enforcement agents often obtain evidence, detain individuals, and elicit confessions in a manner that government actors cannot, which can then be lawfully turned over to the government. Though the same statutory law governing private citizens (assault, false imprisonment, trespass, etc.) also regulates private police conduct, private police conduct is not bound by …

Per Curiam Signals In The Supreme Court's Shadow Docket, Zina Makar

Washington Law Review

Lower courts and litigants depend a great deal on the Supreme Court to articulate and communicate signals regarding how to interpret existing doctrine. Signals are at their strongest and most reliable when they originate from the Court’s merits docket. More recently, the Court has been increasingly relying on its orders docket—colloquially referred to as its “shadow docket”—to communicate with lower courts by summarily reversing and correcting errors in interpretation without briefing or oral argument.

Over the past decade the Roberts Court has granted certiorari to summarily reverse a growing number of qualified immunity cases, issuing over a dozen unsigned per …

Privacy And Property: Constitutional Concerns Of Dna Dragnet Testing, E. Wyatt Jones

Honors Projects

DNA dragnets have attracted both public and scholarly criticisms that have yet to be resolved by the Courts. This review will introduce a modern understanding of DNA analysis, a complete introduction to past and present Fourth and Fourteenth Amendment jurisprudence, and existing suggestions concerning similar issues in legal scholarship. Considering these contexts, this review concludes that a focus on privacy and property at once, with a particular sensitivity to the inseverable relationship between the two interests, is Constitutionally consistent with precedent and the most workable means of answering the question at hand.

The Fourth Amendment In A Digital Age: Defining Boundaries In Law Enforcement Surveillance Of The Home, Josh Hoffman, Jared Xia

Brigham Young University Prelaw Review

As our country enters a new digital age, emerging technologies have increased the ability of law enforcement to monitor American citizens more closely. The tracking of suspects through thermal imaging, video monitoring, and cell phone GPSs are just a few examples of the unlocked potential now available to investigating authorities. When directed at the home, these technologies allow for unprecedented encroachment of our most intimate sphere of daily life. With this accelerating prevalence of technology in surveillance practices comes the need to reassess what boundaries the Fourth Amendment defines for our privacy. This paper explores the application of the Reasonable …

A Square Double Helix In A Round Hole: Forensic Genetic Genealogy Searches And The Fourth Amendment, Matthew Sweat

Georgia State University Law Review

A forensic genetic genealogy search (FGGS) involves law enforcement’s use of consumer DNA databases to generate leads to solve cold cases. As a result of more modern technological processes, the DNA profiles kept in consumer databases are far more revealing than the DNA profiles stored in the FBI’s Combined DNA Index System (CODIS). Accordingly, each DNA profile in a consumer database can be used to identify hundreds of relatives related to the DNA’s contributor.

The government’s use of consumer DNA databases to locate the perpetrators of horrific, unsolved crimes has generated fans and critics. Supporters of FGGSs argue that, in …

Carceral Socialization As Voter Suppression, Danieli Evans

Articles

In an era of mass incarceration, many people are socialized through interactions with the carceral state. These interactions are poweful learning experiences, and by design, they are contrary to democratic citizenship. Citizenship is about belonging to a community of equals, being entitled to mutual respect and concern. Criminal punishment deliberately harms, subordinates, and stigmatizes. Encounters with the carceral system are powerful experiences of anti-democratic socialization, and they impact peoples' sense of citizenship and trust in government. Accordingly, a large body of social science research shows that eligible voters who have carceral contact are significantly less likely to vote or to …

Gone Fishing: Casting A Wide Net Using Geofence Warrants, Ryan Tursi

Washington Law Review

Technology companies across the country receive requests from law enforcement agencies for cell phone location information near the scenes of crimes. These requests rely on the traditional warrant process and are known as geofence warrants, or reverse location search warrants. By obtaining location information, law enforcement can identify potential suspects or persons of interest who were near the scene of a crime when they have no leads. But the use of this investigative technique is controversial, as it threatens to intrude upon the privacy of innocent bystanders who had the misfortune of being nearby when the crime took place. Innocent …

On Warrants & Waiting: Electronic Warrants & The Fourth Amendment, Tracy Hresko Pearl

Indiana Law Journal

Police use of electronic warrant (“e-warrant”) technology has increased significantly in recent years. E-warrant technology allows law enforcement to submit, and magistrate judges to review and approve, warrant applications on computers, smartphones, and tablets, often without any direct communication. Police officers report that they favor e-warrants over their traditional, paper counterparts because they save officers a significant amount of time in applying for warrants by eliminating the need to appear in-person before a magistrate. Legal scholars have almost uniformly praised e-warrant technology as well, arguing that use of these systems will increase the number of warrants issued throughout the United …

Policing "Bad" Mothers, I. Bennett Capers

Faculty Scholarship

Jessamine Chan’s The School for Good Mothers — a speculative novel about a mother who abandons her child for a few hours and is required to attend a school for good mothers to regain custody — may not be a great book, but it is a good yarn, and a page turner, and thought-provoking. Thought-provoking, because to measure her fitness to be a mother, the protagonist is assigned a robot doppelganger of her child — one that is sentient, one that seems almost real, one that might even pass the Turing test, and one that she is required not only …

The Fourth Amendment's Constitutional Home, Gerald S. Dickinson

Articles

The home enjoys omnipresent status in American constitutional law. The Bill of Rights, peculiarly, has served as the central refuge for special protections to the home. This constitutional sanctuary has elicited an intriguing textual and doctrinal puzzle. A distinct thread has emerged that runs through the first five amendments delineating the home as a zone where rights emanating from speech, smut, gods, guns, soldiers, searches, sex, and self-incrimination enjoy special protections. However, the thread inexplicably unravels upon arriving at takings. There, the constitutional text omits and the Supreme Court’s doctrine excludes a special zone of safeguards to the home. This …

Surveillance Technologies And Constitutional Law, Christopher Slobogin, Sarah Brayne

Vanderbilt Law School Faculty Publications

This review focuses on government use of technology to observe, collect, or record potential criminal activity in real-time, as contrasted with “transaction surveillance” that involves government efforts to access already-existing records and exploit Big Data, topics that have been the focus of previous reviews (Brayne 2018, Ridgeway 2018). Even so limited, surveillance technologies come in many guises, including closed-circuit television, automated license plate and facial readers, aerial cameras, and GPS tracking. Also classifiable as surveillance technology are devices such as thermal and electromagnetic imagers that can “see” through walls and clothing. Finally, surveillance includes wiretapping and other forms of communication …

Scanning Iphones To Save Children: Apple’S On-Device Hashing Algorithm Should Survive A Fourth Amendment Challenge, Timothy Gernand

Dickinson Law Review (2017-Present)

When Apple announced it would combat the growth of child sexual abuse material (CSAM) on its platform by scanning all its users’ devices without their consent, many of its loyal customers felt betrayed. With tech companies such as Google and Facebook arranging their business models around selling their customers’ personal information, Apple customers saw the company’s focus on privacy as a refreshing alternative. However, as Apple itself privately acknowledged, this emphasis on privacy had led to it becoming a haven for CSAM. Despite the reputational damage it would incur with its customers, Apple resolved to confront CSAM on its platform …

Beware What You Google: Fourth Amendment Constitutionality Of Keyword Warrants, Chelsa Camille Edano

Washington Law Review

Many Americans have potentially had their privacy rights invaded through invisible, widespread police searches. In recent years, local and federal governments have compelled Google and other search engine companies to produce the personal information of users who have conducted a search query related to a crime. By using keyword warrants, the government can conduct a dragnet search for suspects, imposing suspicion on users and exposing their personal information. The keyword warrant is a symptom of the erosion of the Fourth Amendment protection against suspicionless searches. Not only is scholarship scarce on keyword warrants, but also instances of these warrants are …

The Fourth Amendment And The Problem Of Social Cost, Thomas P. Crocker

Northwestern University Law Review

The Supreme Court has made social cost a core concept relevant to the calculation of Fourth Amendment remedies but has never explained the concept’s meaning. The Court limits the availability of both the exclusionary rule and civil damages because of their “substantial social costs.” According to the Court, these costs primarily consist of letting the lawbreaker go free by excluding evidence or deterring effective police practices that would lead to more criminal apprehension and prosecution. But recent calls for systemic police reform by social movements have a different view of social cost. So too do calls for reforming qualified immunity. …

Rewriting Whren V. United States, Jonathan Feingold, Devon Carbado

Faculty Scholarship

In 1996, the U.S. Supreme Court decided Whren v. United States—a unanimous opinion in which the Court effectively constitutionalized racial profiling. Despite its enduring consequences, Whren remains good law today. This Article rewrites the opinion. We do so, in part, to demonstrate how one might incorporate racial justice concerns into Fourth Amendment jurisprudence, a body of law that has long elided and marginalized the racialized dimensions of policing. A separate aim is to reveal the “false necessity” of the Whren outcome. The fact that Whren was unanimous, and that even progressive Justices signed on, might lead one to conclude that …

A Solution For The Third-Party Doctrine In A Time Of Data Sharing, Contact Tracing, And Mass Surveillance, Tonja Jacobi, Dustin Stonecipher

Notre Dame Law Review

Today, information is shared almost constantly. People share their DNA to track their ancestry or for individualized health information; they instruct Alexa to purchase products or provide directions; and, now more than ever, they use videoconferencing technology in their homes. According to the third-party doctrine, the government can access all such information without a warrant or without infringing on Fourth Amendment privacy protections. This exposure of vast amounts of highly personal data to government intrusion is permissible because the Supreme Court has interpreted the third-party doctrine as a per se rule. However, that interpretation rests on an improper understanding of …
