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 …

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 …

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 …

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 …

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 …

Fourth Amendment Fairness, Richard M. Re

Michigan Law Review

Fourth Amendment doctrine is attentive to a wide range of interests, including security, informational privacy, and dignity. How should courts reconcile these competing concerns when deciding which searches and seizures are “unreasonable”? Current doctrine typically answers this question by pointing to interest aggregation: the various interests at stake are added up, placed on figurative scales, and compared, with the goal of promoting overall social welfare. But interest aggregation is disconnected from many settled doctrinal rules and leads to results that are unfair for individuals. The main alternative is originalism; but historical sources themselves suggest that the Fourth Amendment calls for …

The Fourth Amendment Categorical Imperative, David Gray

Michigan Law Review Online

The vast majority of current Fourth Amendment doctrine is unfounded, incoherent, and dangerous. The culprit is the Supreme Court’s 1967 decision in Katz v. United States, which defines “search” as government conduct that violates subjectively manifested expectations of privacy “that society is prepared to recognize as ‘reasonable.’ ” This is pure applesauce. Nowhere will you find a standard dictionary that defines “search” in these terms. Neither will you hear a native speaker of the English language use “search” in this sense unless her mind has been polluted by a semester of studying criminal procedure. The Court created this definition …

Why Arrest?, Rachel A. Harmon

Michigan Law Review

Arrests are the paradigmatic police activity. Though the practice of arrests in the United States, especially arrests involving minority suspects, is under attack, even critics widely assume the power to arrest is essential to policing. As a result, neither commentators nor scholars have asked why police need to make arrests. This Article takes up that question, and it argues that the power to arrest and the use of that power should be curtailed. The twelve million arrests police conduct each year are harmful not only to the individual arrested but also to their families and communities and to society as …

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 …

Search Incident To Probable Cause?: The Intersection Of Rawlings And Knowles, Marissa Perry

Michigan Law Review

The search incident to arrest exception authorizes an officer to search an arrestee’s person and his or her area of immediate control. This exception is based on two historical justifications: officer safety and evidence preservation. While much of search incident to arrest doctrine is settled, tension exists between two Supreme Court cases, Rawlings v. Kentucky and Knowles v. Iowa, and a crucial question remains unanswered: Must an officer decide to make an arrest prior to commencing a search? In Rawlings, the Supreme Court stated that a search may precede a formal arrest if the arrest follows quickly thereafter. In Knowles, …

Voluntary Disclosure Of Information As A Proposed Standard For The Fourth Amendment's Third-Party Doctrine, Margaret E. Twomey

Michigan Telecommunications & Technology Law Review

The third-party doctrine is a long-standing tenant of Fourth Amendment law that allows law enforcement officers to utilize information that was released to a third party without the probable cause required for a traditional search warrant. This has allowed law enforcement agents to use confidential informants, undercover agents, and access bank records of suspected criminals. However, in a digital age where exponentially more information is shared with Internet Service Providers, e-mail hosts, and social media “friends,” the traditional thirdparty doctrine ideas allow law enforcement officers access to a cache of personal information and data with a standard below probable cause. …

Hassle, Jane Bambauer

Michigan Law Review

Before police perform a search or seizure, they typically must meet the probable cause or reasonable suspicion standard. Moreover, even if they meet the appropriate standard, their evidence must be individualized to the suspect and cannot rely on purely probabilistic inferences. Scholars and courts have long defended the distinction between individualized and purely probabilistic evidence, but existing theories of individualization fail to articulate principles that are descriptively accurate or normatively desirable. They overlook the only benefit that the individualization requirement can offer: reducing hassle. Hassle measures the chance that an innocent person will experience a search or seizure. Because some …

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 Danger Of Nonrandom Case Assignment: How The Southern District Of New York's "Related Cases" Rule Shaped Stop-And-Frisk Rulings, Katherine A. Macfarlane

Michigan Journal of Race and Law

The Southern District of New York’s local rules are clear: “[A]ll active judges . . . shall be assigned substantially an equal share of the categories of cases of the court over a period of time.” Yet for the past fourteen years, Southern District Judge Shira Scheindlin has been granted near-exclusive jurisdiction over one category of case: those involving wide-sweeping constitutional challenges to the New York Police Department’s (NYPD) stop-and-frisk policies. In 1999, Judge Scheindlin was randomly assigned Daniels v. City of New York, the first in a series of high-profile and high-impact stop-and-frisk cases. Since then, she has overseen …

Keeping Up With The Jonses: Making Sure Your History Is Just As Wrong As Everyone Else's, Brian Sawers

Michigan Law Review First Impressions

Before Katz v. United States, a search under the Fourth Amendment required a trespass. If there was no trespass on one’s property, then there was no search. In Katz, a 1967 decision, the U.S. Supreme Court abandoned that approach, instead finding a search without a trespass based on the government’s invasion of a “reasonable expectation of privacy.” In Oliver v. United States, the Court found that trespass was not sufficient to create a search. It found no reasonable expectation of privacy in open fields, and thus no search, even though the defendant had erected “No Trespassing” signs around his property …

The Politics Of Privacy In The Criminal Justice System: Information Disclosure, The Fourth Amendment, And Statutory Law Enforcement Exemptions, Erin Murphy

Michigan Law Review

When criminal justice scholars think of privacy, they think of the Fourth Amendment. But lately its domain has become far less absolute. The United States Code currently contains over twenty separate statutes that restrict both the acquisition and release of covered information. Largely enacted in the latter part of the twentieth century, these statutes address matters vital to modern existence. They control police access to driver's licenses, educational records, health histories, telephone calls, email messages, and even video rentals. They conform to no common template, but rather enlist a variety of procedural tools to serve as safeguards - ranging from …

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 …

A Failure Of The Fourth Amendment & Equal Protection's Promise: How The Equal Protection Clause Can Change Discriminatory Stop And Frisk Policies, Brando Simeo Starkey

Michigan Journal of Race and Law

Terry v. Ohio changed everything. Before Terry, Fourth Amendment law was settled. The Fourth Amendment had long required that police officers have probable cause in order to conduct Fourth Amendment invasions; to administer a "reasonable" search and seizure, the state needed probable cause. But in 1968, the Warren Court, despite its liberal reputation, lowered the standard police officers had to meet to conduct a certain type of search: the so-called "'stop' and 'frisk.'" A "stop and frisk" occurs when a police officer, believing a suspect is armed and crime is afoot, stops the suspect, conducts an interrogation, and pats him …

One More Good Reason For In-Car Videotaping Of Traffic Stops: An Accurate Assessment Of "Consent", Robert L. White

University of Michigan Journal of Law Reform Caveat

There are a number of reasons why legislative reform mandating the use of in-car cameras in police cruisers would benefit the criminal justice system in Illinois. In-car cameras provide evidence for cases involving traffic violations or intoxicated motorists. They produce instantly available training materials. They also assist victims of police misconduct, as well as officers defending themselves against misconduct claims. This Comment looks to add to this list of benefits the role in-car cameras can play in assessing the validity of consents to search that officers obtain during traffic stops.

Signal Lost: Is A Gps Tracking System The Same As An Eyeball?, Eric Andrew Felleman

University of Michigan Journal of Law Reform Caveat

On November 8th, the Supreme Court will hear arguments in United States v. Jones. One of the primary issues in the case is whether law enforcement personnel violated Mr. Jones' Fourth Amendment right to freedom from unreasonable searches and seizures by using a GPS tracking device to monitor the location of his car without a warrant. The 7th Circuit and the 9th Circuit have both recently held that use of GPS tracking is not a search under the Fourth Amendment.

The Latest 4th Amendment Privacy Conundrum: "Stingrays", Max Bulinksi

University of Michigan Journal of Law Reform Caveat

Wired is reporting renewed hubbub regarding statutory and Fourth Amendment protections of individuals’ privacy in the digital age. This time, it comes in the form of federal officers using a fake cellphone tower (called a “stingray”) to locate their suspect, Mr. Rigmaiden, by tracking the location of his cellphone. According to an affidavit submitted to the court, the stingray only captures the equivalent of header information – such as the phone or account number assigned to the aircard as well as dialing, routing and address information involved in the communication.

How United States V. Jones Can Restore Our Faith In The Fourth Amendment, Erica Goldberg

Michigan Law Review First Impressions

United States v. Jones, issued in January of this year, is a landmark case that has the potential to restore a property-based interpretation of the Fourth Amendment to prominence. In 1967, the Supreme Court abandoned its previous Fourth Amendment framework, which had viewed the prohibition on unreasonable searches in light of property and trespass laws, and replaced it with a rule protecting the public’s reasonable expectations of privacy. Although the Court may have intended this reasonable expectations test to provide more protection than a test rooted in property law, the new test in fact made the Justices’ subjective views about …

The "Routine Traffic Stop" From Start To Finish: Too Much "Routine," Not Enough Fourth Amendment, Wayne R. Lafave

Michigan Law Review

Yale Kamisar, about which I have said too much elsewhere in this issue of the Review, could rightly be called "Mr. Confessions," for he has not only authored books and a host of articles on the subject of police interrogation, but for years has been printing Miranda cards in his basement and selling them to police departments all across the nation. Moreover, he may be the only law professor in the country who has both personally coerced a confession and had a confession coerced out of him. As Kamisar has himself noted, my own "intellectual sandbox" has been the …

Bête Noire: How Race-Based Policing Threatens National Security, Lenese C. Herbert

Michigan Journal of Race and Law

This Article asserts that race-based policing, enabled and exacerbated by race-blind judicial review, creates an ire with a purpose that promises, especially after September 11, to make us all less safe. The illegitimate marginalization of American citizens aggravates an already alienated population and primes them for cooperation with those who seek to harm the United States. Race-based policing guts the expectation of fair-dealing, legitimacy, and justice in the criminal justice system, creating marginalized populations, especially of African Americans. Lack of judicial redress in the face of such policing irrevocably stains already beleaguered African Americans (and others so policed) as inferior …

Computer Searches And Seizures: Some Unresolved Issues, Susan W. Brenner, Barbara A. Frederiksen

Michigan Telecommunications & Technology Law Review

The goal of this article is to illustrate the issues that arise in the context of computer search and seizures by examining several areas in which the application of Fourth Amendment concepts to computer searches and/or seizures can be problematic. In order to illustrate this point, the article will build on a hypothetical. The hypothetical situation assumes law enforcement officers have lawfully obtained a warrant to search for and seize evidence concerning the commission of one or more crimes. It will also be assumed that computer technology played some role in the commission of these crimes, so computer equipment and …

(E)Racing The Fourth Amendment, Devon W. Carbado

Michigan Law Review

It's been almost two years since I pledged allegiance to the United States of America - that is to say, became an American citizen. Before that, I was a permanent resident of America and a citizen of the United Kingdom. Yet, I became a black American long before I acquired American citizenship. Unlike citizenship, black racial naturalization was always available to me, even as I tried to make myself unavailable for that particular Americanization process. Given the negative images of black Americans on 1970s British television and the intra-racial tensions between blacks in the U.K. and blacks in America, I …

When Success Breeds Attack: The Coming Backlash Against Racial Profiling Studies, David A. Harris

Michigan Journal of Race and Law

The author proposes that in an ongoing debate on questions concerning the possibility of racial or other types of invidious discrimination by public institutions, we should apply a prima facie standard to these claims in the public arena. In other words, if African Americans or Latinos say that they have been the victims of racial profiling, we should not ask for conclusive proof in the strictest statistical sense; rather, if they can present some credible evidence beyond anecdotes, some statistics that indicate that we may, indeed, have a problem, the burden should then shift to the public institution-here, law enforcement …

Striking A Sincere Balance: A Reasonable Black Person Standard For "Location Plus Evasion" Terry Stops, Mia Carpiniello

Michigan Journal of Race and Law

Randall Susskind originally proposed the "reasonable African American standard” for Terry stops as a way to minimize racial disparities in Fourth Amendment jurisprudence. This paper will expand upon Susskind's suggested standard within the specific context of "location plus evasion" stops, in which suspects are stopped upon flight in a high-crime neighborhood. Part one will present the reasonable Black person standard in the context of Illinois v. Wardlow, a recent "location plus evasion case." Part one will then show how this alternative standard better accounts for Wardlow's "raced" decision to flee, the police officers' "raced" decision to stop him, and …

An Empirically Based Comparison Of American And European Regulatory Approaches To Police Investigation, Christopher Slobogin

Michigan Journal of International Law

This article takes a comparative and empirical look at two of the most significant methods of police investigation: searches for and seizures of tangible evidence and interrogation of suspects. It first compares American doctrine regulating these investigative tools with the analogous rules predominant in Europe. It then discusses research on the American system that sheds light on the relative advantages and disadvantages of the two regulatory regimes.

The Adversity Of Race And Place: Fourth Amendment Jurisprudence In Illinois V. Wardlow, 528 S. Ct. 673 (2000), Adam B. Wolf

Michigan Journal of Race and Law

This Case Note lays out Wardlow's pertinent facts, describes the decisions of the Court and lower courts, and then analyzes the ramifications of the Court's holding. In particular, this Case Note argues that the Court's ruling recognizes substantially less Fourth Amendment protections for people of color and indigent citizens than for wealthy Caucasians. This perpetuates a cycle of humiliating experiences, as well as fear and mistrust of the police by many poor people of color.
