Textual (In)Difference In State Search-And-Seizure Provisions, Quinn Yeargain

Northwestern University Law Review

Over the past 250 years, state constitutional drafters have refined the scope of rights and liberties protected by their constitutions’ texts. Today, all state constitutions include a search-and-seizure provision—and though only a minority follow the layout, text, and context of the Fourth Amendment to the U.S. Constitution, most of them bear a striking resemblance to it. However, textual variations abound. Some of them may seem minor, like using the word “possessions” instead of “effects,” or mandating that warrants describe their intended targets “as nearly as may be” instead of requiring that they “particularly describ[e]” them. But others, like the addition …

(Mis)Judging Suspicion, Sherri Lee Keene

Georgetown Law Faculty Publications and Other Works

Twenty-five years ago, the Supreme Court decided Illinois v. Wardlow, a Fourth Amendment case that allowed the high-crime nature of a location to be considered in determinations of whether there was reasonable suspicion to support a police stop. In making these determinations, courts rarely acknowledge the role that race can play in decisions that factor in the nature of a location as context. Yet even when the race of a defendant is not mentioned, high-crime area designations can act as a proxy for race inviting racial bias into courts’ analyses. Reasonable suspicion analysis involves the interpretation of a suspect’s …

The Fourth Amendment's Hidden Intrusion Doctrine, Laura Ginsberg Abelson

Faculty Journal Articles and Book Chapters

The Fourth Amendment’s concept of probable cause is the linchpin of legal standards governing law enforcement actions such as arrests, searches, and seizures. This article challenges the assumption that the same quantum of evidence can meet the probable cause standard regardless of whether law enforcement seek to conduct a search, to seize evidence, or to make an arrest, and regardless of the intrusiveness of such search or seizure. This paper demonstrates that the Supreme Court implicitly considers the degree of intrusion into privacy or liberty, not just the quantum or quality of evidence, when determining whether probable cause exists. In …

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 …

Pyrrhic Victories: The Mirage Of Winning At The Supreme Court, Tonja Jacobi, Clare G. Willis

Faculty Articles

We conduct in-depth archival research of landmark constitutional criminal procedure cases and find two ways in which the declarations of the vindication of rights they contain are misleading. First, most defendants who successfully establish police violations of their constitutional rights before the highest court in the land nonetheless remain in prison for years or decades subsequently. The multitude of ways in which the state can convict the individual defendant even in the face of one or more constitutional violations means that the Supreme Court precedents that bear their names seldom translate to genuine wins for the defendants. Second, there are …

A Wolf In Sheep’S Attire: How Consent Enfeebles Our Fourth Amendment, Stephen E. Henderson, Guha Krishnamurthi

Faculty Articles

The Fourth Amendment is a mirage. On paper—in the rules studied by law students, analyzed by scholars, and proclaimed by jurists—its limitations are many and, oftentimes, significant. Yet the experience of large numbers of Americans is entirely to the contrary, thanks to the rights-annihilating, under-theorized exception of “consent.” Under its guise, law enforcement officers routinely conduct what would otherwise be constitutionally-restrained searches and seizures, and they do so without meaningful explanation or assent. Fortunately, change—whether legislative or (ideally) constitutional—could be straightforward. Thanks to other sufficient triggers, consent could be replaced by a narrow, rights-protective doctrine under which law enforcement could …

Black Lives Monitored, Chaz Arnett

Faculty Scholarship

The police killing of George Floyd added fuel to the simmering flames of racial injustice in America following a string of similarly violent executions during a global pandemic that disproportionately ravaged the health and economic security of Black families and communities. The confluence of these painful realities exposed deep vulnerabilities and renewed a reckoning with the long unfulfilled promise of racial equality, inspiring large-scale protests around the country and across the globe. As with prior movements for racial justice, from slavery abolition to the civil rights movement’s demand to end Jim Crow, protests have been met with extreme force, either …

Police Brutality As Torture, Nadia Banteka

Scholarly Publications

If racial justice is the most pressing issue in America today, police brutality is the flashpoint. Incident after incident of police brutality during searches and seizures, and within jails and prisons reinforces the conviction within many communities that police harm with impunity those whom they have a duty to protect. Existing criminal statutes are filled with discretionary standards that give deference to officers while civil remedies require victims to surmount the doctrine of qualified immunity. To increase accountability for police brutality, legislatures and courts have so far focused on reducing or eliminating these procedural hurdles. But their changes have not …

Asymmetries, Norm Matching, And The Pursuit Of Equity Between The Police And The Public, Eang Ngov

Faculty Articles

Concerns about police abuse and overcriminalization are on the forefront of public conscientiousness. In spite of the Black Lives Matter movement and calls for police reform, law enforcement officials enjoy a variety of criminal procedure loopholes and double standards, which the United States Supreme Court has ratified through its creation of the open fields, mistake of law, and third party doctrines, as well as its acceptance of deceptive police practices. This Article analyzes the asymmetries between permissible civilian conduct and permissible police conduct to make a broader, systemic critique of the double standards and loopholes that pervade constitutional criminal procedure. …

Let's Make Some "Scents" Of Our Fourth Amendment Rights: The Discriminatory Truths Behind Using The Mere Smell Of Burnt Marijuana As Probable Cause To Search A Vehicle, Alessandra Dumenigo

St. Thomas Law Review

This Comment addresses the negative effects that have resulted and will continue to result if police officers are encouraged by jurisprudence to conduct a warrantless search of an entire vehicle based on the smell of burnt marijuana. Warrantless searches of an entire vehicle based merely on the smell of burnt marijuana grant officers unlimited power that will likely result in police misconduct, an increase in racially profiled traffic stops, and a distrust between police officers and the Black community amid the nationwide outrage over the death of George Floyd. Part II of this Comment discusses the history of the Fourth …

Facial Recognition And The Fourth Amendment, Andrew Ferguson

Scholarly Articles in Law Reviews & 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 …

Stingray Cell-Site Simulator Surveillance And The Fourth Amendment In The Twenty-First Century: A Review Of The Fourth Amendment In An Age Of Surveillance, And Unwarranted, Harvey Gee

St. John's Law Review

(Excerpt)

This Review discusses two timely and insightful books examining the changing relationship between privacy and the Fourth Amendment in the digital era. Part I discusses the tensions between the need to protect privacy rights and the slowly evolving legal landscape during a time of rapidly changing technology, to introduce David Gray’s The Fourth Amendment in an Age of Surveillance. His book explains how the Fourth Amendment, though embattled, can have a prominent role in twenty-first century discussions of privacy, technology, and surveillance. Gray’s analysis is engaged to broaden the conversation about Stingray technology. This section analyzes a sampling of …

The Fourth Amendment Inventory As A Check On Digital Searches, Laurent Sacharoff

Sturm College of Law: Faculty Scholarship

Police and federal agents generally must obtain a warrant to search the tens of thousands of devices they seize each year. But once they have a warrant, courts afford these officers broad leeway to search the entire device, every file and folder, all metadata and deleted data, even if in search of only one incriminating file. Courts avow great reverence for the privacy of personal information under the Fourth Amendment but then claim there is no way to limit where an officer might find the target files, or know where the suspect may have hidden them.

These courts have a …

Core Criminal Procedure, Steven Arrigg Koh

Faculty Scholarship

Constitutional criminal procedural rights are familiar to contemporary criminal law scholars and practitioners alike. But today, U.S. criminal justice may diverge substantially from its centuries-old framework when all three branches recognize only a core set of inviolable rights, implicitly or explicitly discarding others. This criminal procedural line drawing takes place when the U.S. criminal justice system engages in law enforcement cooperation with foreign criminal justice systems in order to advance criminal cases.

This Article describes the two forms of this criminal procedural line drawing. The first is a “core criminal procedure” approach, rooted in fundamental rights, that arises in the …

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 …

A Warrant Requirement Resurgence? The Fourth Amendment In The Roberts Court, Benjamin J. Priester

St. John's Law Review

(Excerpt)

Over many years, the United States Supreme Court has developed an extensive body of precedent interpreting and enforcing the provisions of the Fourth Amendment to the United States Constitution, which prohibits unreasonable searches and seizures by law enforcement agents conducting criminal investigations. Commonly called the “warrant requirement,” one key component of this case law operates to deem some police investigatory techniques to be unconstitutional unless they are conducted pursuant to a search warrant issued in advance by a judge. The terms of the doctrine and its exceptions also authorize other investigatory actions as constitutionally permissible without a search warrant. …

The End Of Intuition-Based High-Crime Areas, Ben Grunwald, Jeffrey A. Fagan

Faculty Scholarship

In 2000, the Supreme Court held in Illinois v. Wardlow that a suspect’s presence in a “high-crime area” is relevant in determining whether an officer has reasonable suspicion to conduct an investigative stop. Despite the importance of the decision, the Court provided no guidance about what that standard means, and over fifteen years later, we still have no idea how police officers understand and apply it in practice. This Article conducts the first empirical analysis of Wardlow by examining data on over two million investigative stops conducted by the New York Police Department from 2007 to 2012.

Anthony Amsterdam's Perspectives On The Fourth Amendment, And What It Teaches About The Good And Bad In Rodriguez V. United States, Tracey Maclin

UF Law Faculty Publications

Anthony Amsterdam’s article, Perspectives On The Fourth Amendment is one of the best, if not the best, law review article written on the Fourth Amendment. Thus, Minnesota Law Review on its hundredth anniversary fittingly recognizes and honors Professor Amsterdam’s article in its Symposium edition, “Standing on the Shoulders of Giants: Celebrating 100 Volumes of the Minnesota Law Review.” I am flattered that the Law Review invited me to participate in this Symposium.

Evidence Laundering In A Post-Herring World, Kay L. Levine, Jenia I. Turner, Ronald F. Wright

Faculty Journal Articles and Book Chapters

The Supreme Court’s decision in Herring v. United States authorizes police to defeat the Fourth Amendment’s protections through a process we call evidence laundering. Evidence laundering occurs when one police officer makes a constitutional mistake when gathering evidence and then passes that evidence along to a second officer, who develops it further and then delivers it to prosecutors for use in a criminal case. When courts admit the evidence based on the good faith of the second officer, the original constitutional taint disappears in the wash.

In the years since Herring was decided, courts have allowed evidence laundering in a …

Teaching Criminal Procedure: Why Socrates Would Use Youtube, Stephen E. Henderson, Joseph Thai

Faculty Articles

In this invited contribution to the Law Journal's annual Teaching Issue, we pay some homage to the great philosopher whose spirit allegedly guides our classrooms, in service of two concrete goals. One, we employ dialogue to describe the “nuts and bolts” of teaching Criminal Procedure, most of which are equally relevant to any doctrinal law school course (including course description, office hours, seating charts and attendance, class decorum and recording, student participation, laptops, textbooks, class preparation and presentation, and exams). Two, we explain the benefits of using multimedia in the classroom, including a few of the many modules found on …

Fourth Amendment Time Machines (And What They Might Say About Police Body Cameras), Stephen E. Henderson

Faculty Articles

When it comes to criminal investigation, time travel is increasingly possible. Despite longstanding roots in traditional investigation, science is today providing something fundamentally different in the form of remarkably complete digital records. And those big data records not only store our past, but thanks to data mining they are in many circumstances eerily good at predicting our future. So, now that we stand on the threshold of investigatory time travel, how should the Fourth Amendment and legislation respond? How should we approach bulk government capture, such as by a solar-powered drone employing wide-area persistent stare technology? Is it meaningfully different …

The Shift Of The Balance Of Advantage In Criminal Litigation: The Case Of Mr. Simpson, David Robinson Jr.

Akron Law Review

The intense public interest in the extraordinary trial and acquittal of Mr. O.J.

Better The Mob And The Ku-Klux: A History Of The Law Of Search And Seizure In Florida, Milton Hirsch

St. Thomas Law Review

As late as 1930, and on several occasions prior to that date, Harvard Law Professor Felix Frankfurter could offer, as an example of something that the Supreme Court would almost never be called upon to decide, "whether the [Fourth Amendment] protection against 'unreasonable searches and seizures' is violated. In 1939 Professor Frankfurter was appointed to the High Court, where he would serve for 23 years; and where, as Justice Frankfurter, he would participate in a great many notable opinions having to do with whether the Fourth Amendment protection against unreasonable searches and seizures had been violated. That Professor Frankfurter made …
