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. Specifically, my article connects two perspectives from Amsterdam’s article — the Fourth Amendment’s concern with discretionary police power and the Framers’ vision of the Fourth Amendment to bar …

Policing Criminal Justice Data, Wayne Logan, Andrew Ferguson

Scholarly Articles in Law Reviews & Journals

This article addresses a matter of fundamental importance to the criminal justice system: the presence of erroneous information in government databases and the limited government accountability and legal remedies for the harm that it causes individuals. While a substantial literature exists on the liberty and privacy perils of large multi-source data assemblage, often termed "big data," this article addresses the risks associated with the collection, generation and use of "small data" (i.e., individual-level, discrete data points). Because small data provides the building blocks for all data-driven systems, enhancing its quality will have a significant positive effect on the criminal justice …

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 …

Cutting Cops Too Much Slack, Wayne A. Logan

Scholarly Publications

Police officers can make mistakes, which, for better or worse, the U.S. Supreme Court has often seen fit to forgive. Police, for instance, can make mistakes of fact when assessing whether circumstances justify the seizure of an individual or search of a residence; they can even be mistaken about the identity of those they arrest. This essay examines yet another, arguably more significant context where police mistakes are forgiven: when they seize a person based on their misunderstanding of what a law prohibits.

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 …

From Fugitives To Ferguson: Repairing Historical And Structural Defects In Legally Sanctioned Use Of Deadly Force, José F. Anderson

All Faculty Scholarship

The lawful use of lethal force to subdue suspected wrongdoers has a long tradition in our nation. There is certainly nothing wrong with securing, incapacitating, or even killing violent persons who pose a serious threat to the lives of innocent individuals. One of the important roles of government is to protect people from harm and keep the peace. Recent events in Ferguson, Missouri, have highlighted the tension between the officers on the beat and citizens on the street. These tensions are not likely to subside unless there are major structural changes in the way the police do their job and …

Future Of The Fourth Amendment: The Problem With Privacy, Poverty And Policing, Kami Chavis Simmons

Faculty Publications

For decades, the reasonable expectation of privacy has been the primary standard by which courts have determined whether a "search" has occurred within the meaning of the Fourth Amendment. The Supreme Court's recent decision in U.S. v. Jones, however, has reinvigorated the physical trespass doctrine's importance when determining whether there has been a "search" triggering constitutional protection. Recognizing the unpredictability of the reasonable expectation of privacy doctrine and that doctrine's bias against the urban poor, many scholars hope that the Jones opinion may ameliorate the class divide that has developed in Fourth Amendment jurisprudence.

The Conversational Consent Search: How “Quick Look” And Other Similar Searches Have Eroded Our Constitutional Rights, Alexander A. Mikhalevsky

Georgia State University Law Review

One area in which law enforcement agencies have stretched constitutional limits concerns the scope of a suspect’s consent to search his or her vehicle. Police forces across the country have tested the limits of consent by asking vague, conversational questions to suspects with the goal of obtaining a suspect’s consent to search, even though that individual may not want to allow the search or may not know that he or she has the right to deny consent.

Conversational phrases like “Can I take a quick look?” or “Can I take a quick look around?” have “emerg[ed] as . . . …

Policing Facts, Seth W. Stoughton

Faculty Publications

The United States Supreme Court’s understanding of police practices plays a significant role in the development of the constitutional rules that regulate officer conduct. As it approaches the questions of whether to engage in constitutional regulation and what form of regulation to adopt, the Court discusses the environment in which officers act, describes specific police practices, and explains what motivates officers. Yet the majority of the Court’s factual assertions are made entirely without support or citation, raising concerns about whether the Court is acting based on a complete and accurate perception. When it comes to policing facts, the Court too …

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 …

Preempting The Police, David Jaros

All Faculty Scholarship

Fighting crime requires that we vest police with extensive discretion so that they can protect the public. Unfortunately, the nature of police work makes it difficult to ensure that law enforcement authority is not abused. This challenge is exacerbated by the fact that a great deal of questionable police activity exists in the legal shadows — unregulated practices that do not violate defined legal limits because they have generally eluded both judicial and legislative scrutiny. Local law enforcement strategies, like the maintenance of unauthorized police DNA databases and the routine practice of initiating casual street encounters, threaten fundamental notions of …

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 …

Maryland V. King: Terry V. Ohio Redux, Tracey Maclin

UF Law Faculty Publications

In Maryland v. King, the Supreme Court addressed whether forensic testing of DNA samples taken from persons arrested for violent felonies violated the Fourth Amendment. The purpose behind DNA testing laws is obvious: collecting and analyzing DNA samples advances the capacity of law enforcement to solve both "cold cases" and future crimes when the government has evidence of the perpetrator's DNA from the crime scene. In a 5-4 decision, the Court, in an opinion by Justice Kennedy, upheld Maryland's DNA testing statute, and presumably the similar laws of twenty-seven other states and the federal government. Although Justice Kennedy's opinion suggests …

Passing The Sniff Test: Police Dogs As Surveillance Technology, Irus Braverman

Journal Articles

In October 2012, the Supreme Court of the United States will review the case of Florida v. Jardines, which revolves around the constitutionality of police canine Franky’s sniff outside a private residence. Essentially, the Court will need to decide whether or not the sniff constitutes a “search” for Fourth Amendment purposes. This Article presents a review of the often-contradictory case law that exists on this question to suggest that underlying the various cases is the Courts’ assumption of a juxtaposed relationship between nature and technology. Where dog sniffs are perceived as a technology, the courts have been inclined to also …

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.
