Are Police Officers Bayesians? Police Updating In Investigative Stops, Jeffrey A. Fagan, Lila J.E. Nojima

Faculty Scholarship

Theories of rational behavior assume that actors make decisions where the benefits of their acts exceed their costs or losses. If those expected costs and benefits change over time, behavior will change accordingly as actors learn and internalize the parameters of success and failure. In the context of proactive policing, police stops that achieve any of several goals — constitutional compliance, stops that lead to “good” arrests or summonses, stops that lead to seizures of weapons, drugs, or other contraband, or stops that produce good will and citizen cooperation — should signal to officers the features of a stop that …

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 …

The Subversions And Perversions Of Shadow Vigilantism, Paul H. Robinson, Sarah M. Robinson

All Faculty Scholarship

This excerpt from the recently published Shadow Vigilantes book argues that, while vigilantism, even moral vigilantism, can be dangerous to a society, the real danger is not of hordes of citizens, frustrated by the system’s doctrines of disillusionment, rising up to take the law into their own hands. Frustration can spark a vigilante impulse, but such classic aggressive vigilantism is not the typical response. More common is the expression of disillusionment in less brazen ways by a more surreptitious undermining and distortion of the operation of the criminal justice system.

Shadow vigilantes, as they might be called, can affect the …

Justice Scalia’S Originalism And Formalism: The Rule Of Criminal Law As A Law Of Rules, Stephanos Bibas

All Faculty Scholarship

Far too many reporters and pundits collapse law into politics, assuming that the left–right divide between Democratic and Republican appointees neatly explains politically liberal versus politically conservative outcomes at the Supreme Court. The late Justice Antonin Scalia defied such caricatures. His consistent judicial philosophy made him the leading exponent of originalism, textualism, and formalism in American law, and over the course of his three decades on the Court, he changed the terms of judicial debate. Now, as a result, supporters and critics alike start with the plain meaning of the statutory or constitutional text rather than loose appeals to legislative …

Terry'S Original Sin, Jeffrey Fagan

Faculty Scholarship

In Mapp v. Ohio, the U.S. Supreme Court extended the due process protections of the exclusionary rule to include all "constitutionally unreasonable searches" that were done without a basis of probable cause. In the seven years after Mapp, when homicide rates in the U.S. nearly doubled, riots broke out in at least forty-seven U.S. cities. During the same era, a heroin epidemic gripped the nation's urban centers, giving rise to street drug markets and associated violence and pressures on law enforcement to curb those markets. As violence increased, a turn in the nation's political culture questioned Mapp's restraints on …

Riley V. California And The Beginning Of The End For The Third-Party Search Doctrine, David A. Harris

Articles

In Riley v. California, the Supreme Court decided that when police officers seize a smart phone, they may not search through its contents -- the data found by looking into the call records, calendars, pictures and so forth in the phone -- without a warrant. In the course of the decision, the Court said that the rule applied not just to data that was physically stored on the device, but also to data stored "in the cloud" -- in remote sites -- but accessed through the device. This piece of the decision may, at last, allow a re-examination of …

Justice Scalia's Fourth Amendment: Text, Context, Clarity, And Occasional Faint-Hearted Originalism, Timothy C. Macdonnell

Scholarly Articles

Since joining the United States Supreme Court in 1986, Justice Scalia has been a prominent voice on the Fourth Amendment, having written twenty majority opinions, twelve concurrences, and six dissents on the topic. Under his pen, the Court has altered its test for determining when the Fourth Amendment should apply; provided a vision to address technology's encroachment on privacy; and articulated the standard for determining whether government officials are entitled to qualified immunity in civil suits involving alleged Fourth Amendment violations. In most of Justice Scalia's opinions, he has championed an originalist/textualist theory of constitutional interpretation. Based on that theory, …

The Law And Economics Of Stop-And-Frisk, David S. Abrams

All Faculty Scholarship

The relevant economic and legal research relating to police use of stop-and-frisk has largely been distinct. There is much to be gained by taking an interdisciplinary approach. This Essay emphasizes some of the challenges faced by those seeking to evaluate the efficacy and legality of stop-and-frisk, and suggests some ways forward and areas of exploration for future research.

Community Control Over Camera Surveillance: A Response To Bennett Capers's "Crime, Surveillance, And Communities", Christopher Slobogin

Vanderbilt Law School Faculty Publications

Professor Capers's article helps stimulate thinking about the way in which community views and individual rights interact. In my view, where police propose to conduct surveillance of groups, as occurs with camera surveillance (including the newly developing drone camera systems)', the affected group should be heavily involved in the authorization process. If the surveillance is authorized, care must be taken to ensure that all members of the group are equally affected by it unless and until individualized suspicion, proportionate to the intrusion, develops. That formula ensures that the interests of both the collective and the individual are protected.

Students, Security, And Race, Jason P. Nance

UF Law Faculty Publications

In the wake of the terrible shootings in Newtown, Connecticut, our nation has turned its attention to school security. For example, several states have passed or are considering passing legislation that will provide new funding to schools for security equipment and law enforcement officers. Strict security measures in schools are certainly not new. In response to prior acts of school violence, many public schools for years have relied on metal detectors, random sweeps, locked gates, surveillance cameras, and law enforcement officers to promote school safety. Before policymakers and school officials invest more money in strict security measures, this Article provides …

Comparative Empiricism And Police Investigative Practices, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In the search and seizure context, the United States is much more heavily wedded to warrants and exclusion than European countries and in the interrogation setting requires more robust warnings than most nations in Europe. Comparative empiricism is an empirical assessment of the relative effectiveness of these types of differences between nations regulatory regimes. In the law enforcement context, this type of assessment might be the only realistic means of determining the combination of mechanisms that best protects against government over-reaching without unduly stymying good police-work. Domestic research that attempts to explore differing regulatory approaches either occurs in experimental settings …

Government Dragnets, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This article examines group-focused police investigation techniques - for instance, roadblocks, drug testing programs, area or industry-wide health and safety inspections, data mining, and camera surveillance - a phenomenon referred to as "government dragnets" because these general searches and seizures attempt to cull out bad actors through ensnaring a much larger number of individuals who are innocent of any wrongdoing. The courts have imposed few limitations on dragnets. Recent commentary has either advocated an even more laissez-faire attitude toward these group search and seizures or, at the other end of the spectrum, proposed schemes that would make most of them …

Picture This: Body Worn Video Devices ('Head Cams') As Tools For Ensuring Fourth Amendment Compliance By Police, David A. Harris

Articles

A new technology has emerged with the potential to increase police compliance with the law and to increase officers’ accountability for their conduct. Called “body worn video” (BWV) or “head cams,” these devices are smaller, lighter versions of the video and audio recording systems mounted on the dash boards of police cars. These systems are small enough that they consist of something the size and shape of a cellular telephone earpiece, and are worn by police officers the same way. Recordings are downloaded directly from the device into a central computer system for storage and indexing, which protects them from …

How Accountability-Based Policing Can Reinforce - Or Replace - The Fourth Amendment Exclusionary Rule, David A. Harris

Articles

In Hudson v. Michigan, a knock-and-announce case, Justice Scalia's majority opinion came close to jettisoning the Fourth Amendment exclusionary rule. The immense costs of the rule, Scalia said, outweigh whatever benefits might come from it. Moreover, police officers and police departments now generally follow the dictates of the Fourth Amendment, so the exclusionary rule has outlived the reasons that the Court adopted it in the first place. This viewpoint did not become the law because Justice Kennedy, one member of the five-vote majority, withheld his support from this section of the opinion. But the closeness of the vote on …

The 'High Crime Area' Question: Requiring Verifiable And Quantifiable Evidence For Fourth Amendment Reasonable Suspicion Analysis, Andrew Ferguson, Damien Bernache

Articles in Law Reviews & Other Academic Journals

This article proposes a legal framework to analyze the "high crime area" concept in Fourth Amendment reasonable suspicion challenges.Under existing Supreme Court precedent, reviewing courts are allowed to consider that an area is a "high crime area" as a factor to evaluate the reasonableness of a Fourth Amendment stop. See Illinois v. Wardlow, 528 U.S. 119 (2000). However, the Supreme Court has never defined a "high crime area" and lower courts have not reached consensus on a definition. There is no agreement on what a "high-crime area" is, whether it has geographic boundaries, whether it changes over time, whether it …

Reflections On Standing: Challenges To Searches And Seizures In A High Technology World, José F. Anderson

All Faculty Scholarship

Among the profound issues that surround constitutional criminal procedure is the obscure often overlooked issue of who has standing to challenge an illegal search, seizure or confession. Privacy interests are often overlooked because without a legal status that allows a person to complain in court, there is no way to challenge whether one is constitutionally protected from personal invasions. Standing is that procedural barrier often imposed to prevent a person in a case from objecting to improper police conduct because of his or her relationship of ownership, proximity, location, or interest in an item searched or a thing seized. Although …

Unconstitutional Police Searches And Collective Responsibility, Bernard E. Harcourt

Faculty Scholarship

Then the police officer told the suspect, without just cause, "I bet you are hiding [drugs] under your balls. If you have drugs under your balls, I am going to fuck your balls up."

Jon Gould and Stephen Mastrofski document astonishingly high rates of unconstitutional police searches in their groundbreaking article, "Suspect Searches: Assessing Police Behavior Under the U.S. Constitution." By their conservative estimate, 30% of the 115 police searches they studied – searches that were conducted by officers in a department ranked in the top 20% nationwide, that were systematically observed by trained field observers, and that were coded …

Accountability Solutions In The Consent Search And Seizure Wasteland, José F. Anderson

All Faculty Scholarship

The legal and social issues that have emerged out of the doctrine that people in America have a right against unreasonable government instituted searches and seizures have dominated the dialogue and controversy in the American criminal justice system over the last three decades. A large portion of the debate has centered around the controversial exclusionary rule, which frees the sometimes unmistakably guilty because of irregularities in police procedure.

The notion that society suffers when criminals go free because of the constable's blunder has struck a decidedly political note in the discussion over criminal justice reform. Many observers are quick to …

Police Under The Gun, Richard C. Reuben

Faculty Publications

Back in 1968, Justice William O. Douglas warned in a dissenting opinion in Terry v. Ohio, 392 U.S. 1, that the Court was opening a Pandora's box by eschewing the traditional "probable cause" standard for Fourth Amendment search and seizures in traffic stop cases, and permitting warrantless detentions based merely on "reasonable suspicion."

More than a quarter-century later, the confusion over the "reasonable suspicion" approach is still commanding the Supreme Court's attention. A pair of cases on the justices' argument calendar this spring address the tension between legitimate traffic stops and those based on pretext.

Unspeakable Suspicions: Challenging The Racist Consensual Encounter, Peter Schoenburg, Risa Evans

Law Faculty Scholarship

[Excerpt] "In recent years, law enforcement officials have honed a new technique for fighting the "War on Drugs:" the suspicionless police sweep of stations and vehicles involved in interstate mass transportation. Single officers or groups of officers approach unfortunate individuals in busses, trains, stations and airline terminals. A targeted traveller is requested to show identification and tickets, explain the purpose of his or her travels, and finally, at times, to consent to a luggage search. As long as "a reasonable person would understand that he or she could refuse to cooperate," the encounter between the law-enforcement official and the traveller …

The Fourth Amendment And Its Exclusionary Rule, Yale Kamisar

Articles

"The history of liberty," Justice Felix Frankfurter once noted, "has largely been the history of observance of procedural safeguards" and "the history of the destruction of liberty," Professor Anthony Amsterdam has added, "has largely been the history of the relaxation of those safeguards in the face of plausible sounding governmental claims of a need to deal with widely frightening and emotion freighted threats to the good order of society." These plausible-sounding government claims are being heard today -and they are putting enormous pressure on the Fourth Amendment, the constitutional provision that protects "the right of the people to be secure …

Political Surveillance And The Fourth Amendment, Alan Meisel

Articles

The United States District Court case has left the scope of the warrant protection of the fourth amendment considerably clearer and broader. The door left ajar in Katz has been firmly fastened shut by the Court leaving only the traditional exceptions to the warrant requirement, which are based upon practical necessity, and the still unconfronted question of the power of the executive to conduct warrantless surveillances of foreign agents in national security cases." It is also clear that courts are no less competent to evaluate the appropriateness of a search and seizure in an internal security case than in a …
