The Automated Fourth Amendment, Maneka Sinha

Emory Law Journal

Courts routinely defer to police officer judgments in reasonable suspicion and probable cause determinations. Increasingly, though, police officers outsource these threshold judgments to new forms of technology that purport to predict and detect crime and identify those responsible. These policing technologies automate core police determinations about whether crime is occurring and who is responsible.

Criminal procedure doctrine has failed to insist on some level of scrutiny of—or skepticism about—the reliability of this technology. Through an original study analyzing numerous state and federal court opinions, this Article exposes the implications of law enforcement’s reliance on these practices given the weighty interests …

Crimes Of Suspicion, Lauryn P. Gouldin

Emory Law Journal

Requiring that officers have suspicion of specific crimes before they seize people during stops or arrests is a fundamental rule-of-law limitation on government power. Until very recently, the Supreme Court studiously avoided saying whether reasonable suspicion for street and traffic stops must be crime specific, and lower courts are sharply divided as a result. Statements made in Kansas v. Glover that the Fourth Amendment requires reasonable suspicion of a “particular crime” or of “specific criminal activity” may reflect an effort to rehabilitate this foundational principle, but crime specificity was not the Court’s focus in Glover. Meanwhile, Fourth Amendment scholars, even …

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 …

A Synthesis Of The Science And Law Relating To Eyewitness Misidentifications And Recommendations For How Police And Courts Can Reduce Wrongful Convictions Based On Them, Henry F. Fradella

Seattle University Law Review

The empirical literature on perception and memory consistently demonstrates the pitfalls of eyewitness identifications. Exoneration data lend external validity to these studies. With the goal of informing law enforcement officers, prosecutors, criminal defense attorneys, judges, and judicial law clerks about what they can do to reduce wrongful convictions based on misidentifications, this Article presents a synthesis of the scientific knowledge relevant to how perception and memory affect the (un)reliability of eyewitness identifications. The Article situates that body of knowledge within the context of leading case law. The Article then summarizes the most current recommendations for how law enforcement personnel should—and …

Fourth Amendment Infringement Is Afoot: Revitalizing Particularized Reasonable Suspicion For Terry Stops Based On Vague Or Discrepant Suspect Descriptions, Caroline E. Lewis

William & Mary Law Review

In Terry v. Ohio, the Supreme Court granted law enforcement broad power to perform a limited stop and search of someone when an officer has reasonable suspicion that the person is engaged in criminal activity. The resulting “Terry stop” created a way for police officers to investigate a suspicious person without requiring full probable cause for an arrest. The officer need only have “reasonable suspicion supported by articulable facts” based on the circumstances and the officer’s policing “experience that criminal activity may be afoot.” Reasonable suspicion is—by design—a broad standard, deferential to police officers’ judgment. Law enforcement officers …

Imposing A Daily Burden On Thousands Of Innocent Citizens: The Supreme Court Unnecessarily Limited Motorists' Fourth Amendment Rights In Kansas V. Glover, George M. Dery

William & Mary Journal of Race, Gender, and Social Justice

This Article analyzes Kansas v. Glover, in which the Supreme Court ruled that an officer could stop a vehicle owned by a person having a revoked license on the assumption that the owner was currently driving the vehicle. This work examines the concerns created by Glover’s ruling. This Article asserts that, in creating its new rule enabling police to stop a motorist without first confirming his or her identity, the Court based its holding on the existence of two facts, thus effectively changing its traditional “totality of the circumstances” analysis for reasonable suspicion to a categorical rule. Further, …

Suspicionless Policing, Julian A. Cook

Scholarly Works

The tragic death of Elijah McClain—a twenty-three-year-old, slightly built, unarmed African American male who was walking home along a sidewalk when he was accosted by three Aurora, Colorado police officers—epitomizes the problems with policing that have become a prominent topic of national conversation. Embedded within far too many police organizations is a culture that promotes aggressive investigative behaviors and a disregard for individual liberties. Incentivized by a Supreme Court that has, over the course of several decades, empowered the police with expansive powers, law enforcement organizations have often tested—and crossed—the constitutional limits of their investigative authorities. And too often it …

Making The Impractical, Practical: A Modest And Overdue Approach To Reforming Fourth Amendment Consent Search Doctrine, Augustine P. Manga

William & Mary Journal of Race, Gender, and Social Justice

At some point in your life, you may have a personal encounter with a police officer. During that moment, you may feel utterly powerless, especially if you do not know your rights. One important right that police are not required to inform people of is their right to deny an officer’s request to search their property. Forty-eight years ago, the Supreme Court made its position clear in Schneckloth v. Bustamonte that requiring law enforcement to provide citizens with this warning would be “thoroughly impractical.” Since then, the relationship between law enforcement and society—especially communities of color—has gradually deteriorated, and states …

Perils Of The Reverse Silver Platter Under U.S. Border Patrol Operations, D. Anthony

University of Massachusetts Law Review

In the face of expanding U.S. Border Patrol operations across the country, that agency often acquires evidence during its searches that is unrelated to immigration or other federal crimes but may involve state crimes. States are then faced with the question of whether to accept such evidence for state prosecutions when it was lawfully obtained by federal agents consistent with federal law but in violation of the state’s own search and seizure provisions. Sometimes referred to as “reverse silver platter” evidence, states have come to widely varying conclusions as to the admissibility of federally obtained evidence that would clearly have …

Facial Recognition And The Fourth Amendment, Andrew Ferguson

Articles in Law Reviews & Other Academic Journals

Facial recognition offers a totalizing new surveillance power. Police now have the capability to monitor, track, and identify faces through networked surveillance cameras and datasets of billions of images. Whether identifying a particular suspect from a still photo, or identifying every person who walks past a digital camera, the privacy and security impacts of facial recognition are profound and troubling.

This Article explores the constitutional design problem at the heart of facial recognition surveillance systems. One might hope that the Fourth Amendment – designed to restrain police power and enacted to limit governmental overreach – would have something to say …

The Sacred Fourth Amendment Text, Christopher Slobogin

Michigan Law Review Online

The Supreme Court’s jurisprudence governing the Fourth Amendment’s “threshold”—a word meant to refer to the types of police actions that trigger the amendment’s warrant and reasonableness requirements—has confounded scholars and students alike since Katz v. United States. Before that 1967 decision, the Court’s decisions on the topic were fairly straightforward, based primarily on whether the police trespassed on the target’s property or property over which the target had control. After that decision—which has come to stand for the proposition that a Fourth Amendment search occurs if police infringe an expectation of privacy that society is prepared to recognize as …

The Fourth Amendment At Home, Thomas P. Crocker

Indiana Law Journal

A refuge, a domain of personal privacy, and the seat of familial life, the home holds a special place in Fourth Amendment jurisprudence. Supreme Court opinions are replete with statements affirming the special status of the home. Fourth Amendment text places special emphasis on securing protections for the home in addition to persons, papers, and effects against unwarranted government intrusion. Beyond the Fourth Amendment, the home has a unique place within constitutional structure. The home receives privacy protections in addition to sheltering other constitutional values protected by the Due Process Clause and the First Amendment. For example, under the Due …

How Definitive Is Fourth Amendment Textualism?, Evan H. Caminker

Michigan Law Review Online

Professor Jeffrey Bellin’s excellent article advances a comprehensive and straightforward textual approach to determining what policing activities constitute “searches” triggering the protections of the Fourth Amendment. Bellin’s thesis is that a text-based approach to interpreting the Amendment is superior to the Supreme Court’s current approach, which ever since Katz v. United States has defined “search” primarily by reference to a non-textual “reasonable expectation of privacy” standard. After soundly criticizing the ungrounded and highly subjective nature of the Katz test, Bellin declares that the Court should instead simply follow where the text leads: the Amendment protects people from a search, meaning …

Please Stop: The Law Court's Recent Roadblock Decisions, Jonathan A. Block

Maine Law Review

Police checkpoints or “roadblocks” have become an increasingly utilized law enforcement tool. At best, these checkpoints result in only a minor inconvenience to motorists. When abused, however, roadblocks have the potential for invidious invasions of privacy and personal freedom. Roadblocks are designed to deter, and to a lesser extent detect, criminal activity by stopping everyone—both the guilty and the law-abiding—for a brief inspection, thereby impinging to some degree on one's freedom of travel, privacy, and “right to be let alone.” Such “seizures” must be “reasonable” under the Fourth Amendment in order to survive constitutional challenge. The major difference between roadblocks …

Cops And Cars: How The Automobile Drove Fourth Amendment Law, Tracey Maclin

Faculty Scholarship

This is an essay on Professor Sarah A. Seo’s new book, Policing the Open Road: How Cars Transformed American Freedom (Harvard Univ. Press 2019). I focus on Professor Seo’s analysis of Carroll v. United States, 267 U.S. 132 (1925) and Brinegar v. United States, 338 U.S. 160 (1949). Carroll is important not only because it was the Court’s first car case. Understanding Carroll (and Brinegar, which solidified and expanded Carroll’s holding) is essential because, nearly one hundred years later, its logic continues to direct how the modern Court resolves Fourth Amendment claims of motorists. Put simply, a majority of today’s …

To Knock Or Not To Knock? No-Knock Warrants And Confrontational Policing, Brian Dolan

St. John's Law Review

(Excerpt)

This Note proceeds in three parts. Part I begins by explaining what no-knock warrants are and why they are used. Part I then addresses recent state legislative efforts to reform no-knock warrant use and argues that these efforts, however well-intentioned, are insufficient. Part I will also provide a brief history of how no-knock warrant use developed and gives an overview of the current status of state law regarding no-knock warrants. Part II argues that, contrary to the arguments of no-knock proponents, elimination of no-knock warrants and strict adherence to the knock-and-announce requirement is a more effective way to ensure …

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 …

Location Tracking And Digital Data: Can Carpenter Build A Stable Privacy Doctrine?, Evan H. Caminker

Articles

In Carpenter v United States, the Supreme Court struggled to modernize twentieth-century search and seizure precedents for the “Cyber Age.” Twice previously this decade the Court had tweaked Fourth Amendment doctrine to keep pace with advancing technology, requiring a search warrant before the government can either peruse the contents of a cell phone seized incident to arrest or use a GPS tracker to follow a car’s long-term movements.

Tort Justice Reform, Paul David Stern

University of Michigan Journal of Law Reform

This Article calls for a comprehensive reform of public tort law with respect to law enforcement conduct. It articulates an effective and equitable remedial regime that reconciles the aspirational goals of public tort law with the practical realities of devising payment and disciplinary procedures that are responsive to tort settlements and judgments. This proposed statutory scheme seeks to deter law enforcement misconduct without disincentivizing prudent officers from performing their duties or overburdening them with extensive litigation. Rather than lamenting the dissolution of Bivens v. Six Unknown Named Agents of Federal Bureau of Narcotics or the insurmountability of qualified immunity, reform …

The Quantum Of Suspicion Needed For An Exigent Circumstances Search, Kit Kinports

University of Michigan Journal of Law Reform

For decades, the United States Supreme Court opinions articulating the standard of exigency necessary to trigger the exigent circumstances exception to the Fourth Amendment’s warrant requirement have been maddeningly opaque and confusing. Some cases require probable cause, others call for reasonable suspicion, and still, others use undefined and unhelpful terms such as “reasonable to believe” in describing how exigent the situation must be to permit the police to proceed without a warrant. Not surprisingly, the conflicting signals coming from the Supreme Court have led to disagreement in the lower courts.

To resolve this conflict and provide guidance to law enforcement …

Nowhere To Run, Nowhere To Hide.* Applying The Fourth Amendment To Connected Cars In The Internet-Of-Things Era, Gregory C. Brown, Jr.

Journal of Civil Rights and Economic Development

(Excerpt)

Part I of this Note will briefly discuss the key components of a Connected Car, identify who collects the data from the Car, and examine the various uses for the data. Part I also explores whether Car owners consent to the collection of their Car’s data. Part II-A will trace the historical development of the automobile exception to the Fourth Amendment, which generally permits law-enforcement officers to conduct a warrantless search of a vehicle. Part II-B will discuss how the Supreme Court has applied the Fourth Amendment to pre-Internet technologies. Part II-C will discuss two recent Fourth Amendment Supreme …

When A Tent Is Your Castle: Constitutional Protection Against Unreasonable Searches Of Makeshift Dwellings Of Unhoused Persons, Evanie Parr

Seattle University Law Review

This Note will argue that all jurisdictions should follow the Washington State Court of Appeals, Division II in validating makeshift dwellings used by people experiencing homelessness as spaces protected from unwarranted police intrusions by shifting evaluations of “reasonable expectations of privacy” to a more equitable standard that appreciates the realities of economic disparity. This approach to constitutional protections against unreasonable searches and seizures is imperative to protect the rights of people experiencing homelessness, given that such individuals are regularly subjected to invasions of privacy and heightened exposure to the criminal justice system.

Byrd V United States: Unauthorized Drivers Of Rental Cars Have Fourth Amendment Rights? Not As Evident As It Seems, Tracey Maclin

Faculty Scholarship

No discerning student of the Supreme Court would contend that Justice Anthony Kennedy broadly interpreted the Fourth Amendment during his thirty years on the Court. His majority opinions in Maryland v. King, Drayton v. United States and his willingness to join the three key sections of Justice Scalia’s opinion in Hudson v. Maryland, which held that suppression is never a remedy for knock-and-announce violations, are just a few examples of Justice Kennedy’s narrow view of the Fourth Amendment.

In light of his previous votes in search and seizure cases, surprisingly Justice Kennedy, in what would be his final Fourth Amendment …

Policing, Danger Narratives, And Routine Traffic Stops, Jordan Blair Woods

Michigan Law Review

This Article presents findings from the largest and most comprehensive study to date on violence against the police during traffic stops. Every year, police officers conduct tens of millions of traffic stops. Many of these stops are entirely unremarkable—so much so that they may be fairly described as routine. Nonetheless, the narrative that routine traffic stops are fraught with grave and unpredictable danger to the police permeates police training and animates Fourth Amendment doctrine. This Article challenges this dominant danger narrative and its centrality within key institutions that regulate the police.

The presented study is the first to offer an …

Perceptions, Knowledge And Experiences Among Police Officers: Traffic Stops, Vehicle Searches And K-9 Involvement, Daniel Ozment

Master of Science in Criminal Justice Theses & (Pre-2016) Policy Research Projects

This survey study explores the perceptions, knowledge and experiences of police “line” officers concerning Fourth Amendment search and seizure norms and applications during traffic stops and vehicles searches, in particular police use of canine units following the landmark United States Supreme Court decision of Rodriguez v. United States. In particular, the study examines issues surrounding the length and scope of a traffic stop by police, including stops with canine involvement. Finally, the study includes an analysis of how federal courts of appeal and Georgia courts have interpreted the Rodriguez decision.
