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 …

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.

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.

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.

The Rise, Decline And Fall(?) Of Miranda, Yale Kamisar

Articles

There has been a good deal of talk lately to the effect that Miranda1 is dead or dying-or might as well be dead.2 Even liberals have indicated that the death of Miranda might not be a bad thing. This brings to mind a saying by G.K. Chesterton: "Don't ever take a fence down until you know the reason why it was put up."4

Bringing Clarity To Administrative Search Doctrine: Distinguishing Dragnets From Special Subpopulation Searches, Eve Brensike Primus

Articles

Anyone who has been stopped at a sobriety checkpoint, screened at an international border, scanned by a metal detector at an airport or government building, or drug tested for public employment has been subjected to an administrative search or seizure. Searches of public school students, government employees, and probationers are characterized as administrative, as are business inspections and-increasingly-wiretaps and other searches used in the gathering of national security intelligence. In other words, the government conducts thousands of administrative searches every day. None of these searches requires either probable cause or a search warrant. Instead, courts evaluating administrative searches need only …

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.

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 …

Hanging On By A Thread: The Exclusionary Rule (Or What's Left Of It) Lives For Another Day, David A. Moran

Articles

Back when there was a Soviet Union, foreign intelligence officers would anxiously await the May Day parade in Moscow to see who would be standing next to the chairman of the Communist Party and who would be missing from the reviewing platform altogether. Since the Soviet government and the statecontrolled press published very little about what was really going on in the halls of state power, this was considered the most reliable way to determine who was in or out of favor and, by extension, how the domestic and foreign policies of the world's second most powerful country were likely …

Disentangling Administrative Searches, Eve Brensike Primus

Articles

Everyone who has been screened at an international border, scanned by an airport metal detector, or drug tested for public employment has been subjected to an administrative search. Since September 11th, the government has increasingly invoked the administrative search exception to justify more checkpoints, unprecedented subway searches, and extensive wiretaps. As science and technology advance, the frequency and scope of administrative searches will only expand. Formulating the boundaries and requirements of administrative search doctrine is therefore a matter of great importance. Yet the rules governing administrative searches are notoriously unclear. This Article seeks to refocus attention on administrative searches and …

Waiting For The Other Shoe: Hudson And The Precarious State Of Mapp, David A. Moran

Articles

I have no idea whether my death will be noted in the New York Times. But if it is, I fear the headline of my obituary will look something like: "Professor Dies; Lost Hudson v. Michigan' in Supreme Court, Leading to Abolition of Exclusionary Rule." The very existence of this Symposium panel shows, I think, that my fear is well-grounded. On the other hand, I am not quite as fearful that Hudson foreshadows the complete overruling of Mapp v. Ohio2 and Weeks v. United States3 as I was when I published an article just three months after the Hudson decision …

Jail Strip-Search Cases: Patterns And Participants, Margo Schlanger

Articles

Among Marc Galanter’s many important insights is that understanding litigation requires understanding its participants. In his most-cited work, Why the “Haves” Come Out Ahead, Galanter pioneered a somersault in the typical approach to legal institutions and legal change: Most analyses of the legal system start at the rules end and work down through institutional facilities to see what effect the rules have on the parties. I would like to reverse that procedure and look through the other end of the telescope. Let’s think about the different kinds of parties and the effect these differences might have on the way the …

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 …
