Justifying The Fourth Amendment, Daniel Epps

Vanderbilt Law Review

Why does the Fourth Amendment belong in the Constitution? This question is not whether society should impose some legal restraints on government searches and seizures. Rather, why should such protections reside in our national charter, superior to other forms of law and insulated from change via ordinary majoritarian political processes? Despite major disputes about the Fourth Amendment's content, Fourth Amendment theorists rarely ask this question. Almost all agree that the Fourth Amendment's constitutional protections are critically important-even if no one can agree exactly what those protections are.
This Article seeks a justification for the Fourth Amendment-the reason why search-and-seizure protections …

Race, The Academy, And The Constitution Of The War On Drugs, Jeffrey Bellin, Bennett Capers

Vanderbilt Law School Faculty Publications

The war on drugs is widely viewed as a policy failure. Despite massive government intrusions on personal liberty, drug addiction, overdoses, and drug-related violence have only in- creased since the war was declared in 1971. David Pozen's new book, The Constitution of the War on Drugs, reveals a constitutional failure as well. Pozen chronicles a host of constitutional arguments that American litigants deployed to protect a "right" to use drugs with surprising, if fleeting, suc- cess. Pozen asks what might have been, exploring why the courts backtracked and effectively re- moved the Constitution as a meaningful obstacle to drug prohibitions. …

The Harms Of Heien: Pulling Back The Curtain On The Court's Search And Seizure Doctrin, Wayne A. Logan

Vanderbilt Law Review

In Heien v. North Carolina, the Supreme Court held that individuals can be seized on the basis of reasonable police mistakes of law. In an opinion authored by Chief Justice Roberts, the eight-Justice majority held that the Fourth Amendment's prohibition of "unreasonable" seizures does not bar legally mistaken seizures because "[t]o be reasonable is not to be perfect." Concurring, Justice Kagan, joined by Justice Ginsburg, emphasized that judicial condonation of police mistakes of law should be "exceedingly rare." In a solo dissent, Justice Sotomayor fairly "wonder[ed] why an innocent citizen should be made to shoulder the burden of being seized …

The Harms Of Heien: Pulling Back The Curtain On The Court's Search And Seizure Doctrine, Steven M. Goldstein --

Vanderbilt Law Review

In Heien v. North Carolina, the Supreme Court held that individuals can be seized on the basis of reasonable police mistakes of law.

Breaking The Fourth's Wall: The Implications Of Remote Education For Students' Fourth Amendment Rights, Sallie Hatfield

Vanderbilt Journal of Entertainment & Technology Law

As the COVID-19 pandemic forced both public K-12 and higher education institutions to transition to exclusively provide remote education, students’ homes and personal lives were exposed to the government like never before. Zoom classes and remote proctoring were suddenly the norm. Students and their families scrambled to create appropriate offices and classroom spaces in their homes, and many awkward and invasive scenarios soon followed. While many may have been harmlessly captured on camera, like classes that witness a student’s family eating lunch in the background or a dog on the couch, even these harmless instances have insidious implications for the …

Administrative Regulation Of Programmatic Policing: Why "Leaders Of A Beautiful Struggle" Is Both Right And Wrong, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In Leaders of a Beautiful Struggle v. Baltimore Police Department, the Fourth Circuit Court of Appeals held that Aerial Investigation Research (AIR), Baltimore's aerial surveillance program, violated the Fourth Amendment because it was not authorized by a warrant. AIR was constitutionaly problematic, but not for the reason given by the Fourth Circuit. AIR, like many other technologically-enhanced policing programs that rely on closed-circuit television (CCTV), automated license plate readers and the like, involves the collection and retention of information about huge numbers ofpeople. Because individualized suspicion does not exist with respect to any of these people's information, an individual-specific warrant …

Equality In The Streets: Using Proportionality Analysis To Regulate Street Policing, Christopher Slobogin

Vanderbilt Law School Faculty Publications

The racially disparate impact and individual and collective costs of stop and frisk, misdemeanor arrests, and pretextual traffic stops have been well documented. Less widely noticed is the contrast between Supreme Court case law permitting these practices and the Court's recent tendency to strictly regulate technologically enhanced searches that occur outside the street policing setting and that--coincidentally or not--happen to be more likely to affect the middle class. If, as the Court has indicated, electronic tracking and searches of digital records require probable cause that evidence of crime will be found, stops and frisks should also require probable cause that …

A World Of Difference? Law Enforcement, Genetic Data, And The Fourth Amendment, Christopher Slobogin, J. W. Hazel

Vanderbilt Law School Faculty Publications

Law enforcement agencies are increasingly turning to genetic databases as a way of solving crime, either through requesting the DNA profile of an identified suspect from a database or, more commonly, by matching crime scene DNA with DNA profiles in a database in an attempt to identify a suspect or a family member of a suspect. Neither of these efforts implicates the Fourth Amendment, because the Supreme Court has held that a Fourth Amendment "search" does not occur unless police infringe "expectations of privacy society is prepared to recognize as reasonable" and has construed that phrase narrowly, without reference to …

Police As Community Caretakers: Caniglia V. Strom, Christopher Slobogin

Vanderbilt Law School Faculty Publications

What is the proper role of the police? That question has been at the forefront of debates about policing for quite some time, but especially in the past year. One answer, spurred by countless news stories about black people killed by law enforcement officers, is that the power of the police should be reduced to the bare minimum, with some in the Defund the Police movement calling for outright abolition of local police departments. Toward the other end of the spectrum is the notion that the role of the police in modern society is and must be capacious. Police should …

Primer On Risk Assessment For Legal Decision-Makers, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This primer is addressed to judges, parole board members, and other legal decisionmakers who use or are considering using the results of risk assessment instruments (RAIs) in making determinations about post-conviction dispositions, as well as to legislators and executive officials responsible for authorizing such use. It is meant to help these decisionmakers determine whether a particular RAI is an appropriate basis for legal determinations and whether evaluators who rely on an RAI have done so properly. This primer does not take a position on whether RAIs should be integrated into the criminal process. Rather, it provides legal decision-makers with information …

The Sacred Fourth Amendment Text, Christopher Slobogin

Vanderbilt Law School Faculty Publications

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 reasonable--scholars …

Fourth Amendment Textualism, Jeffrey Bellin

Vanderbilt Law School Faculty Publications

The Fourth Amendment's prohibition of "unreasonable searches" is one of the most storied constitutional commands. Yet after decades of Supreme Court jurisprudence, a coherent definition of the term "search" remains surprisingly elusive. Even the justices know they have a problem. Recent opinions only halfheartedly apply the controlling "reasonable expectation of privacy" test and its wildly unpopular cousin, "third-party doctrine," with a few justices in open revolt. These fissures hint at the Court's openness to a new approach. Unfortunately, no viable alternatives appear on the horizon. The justices themselves offer little in the way of a replacement. And scholars' proposals exhibit …

Going Postal: Analyzing The Abuse Of Mail Covers Under The Fourth Amendment, Julie L. Rooney

Vanderbilt Law Review

Since at least the late 1800s, the United States government has regularly tracked the mail of many of its citizens. In 2014 alone, for example, the government recorded all data on the outside of the mail parcels of over 50,000 individuals via a surveillance initiative known as the mail covers program. In the current age of mass surveillance, this program-like all surveillance initiatives-has grown exponentially. Unbeknownst to most citizens, the government now photographs and records the exterior of each of the roughly 160 billion mail parcels delivered by the USPS every year. Still, despite its ability to allow governmental authorities …

Policing As Administration, Christopher Slobogin

Vanderbilt Law School Faculty Publications

Police agencies should be governed by the same administrative principles that govern other agencies. This simple precept would have significant implications for regulation of police work, in particular the type of suspicionless, group searches and seizures that have been the subject of the Supreme Court's special needs jurisprudence (practices that this Article calls "panvasive"). Under administrative law principles, when police agencies create statute-like policies that are aimed at largely innocent categories of actors-as they do when administering roadblocks, inspection regimes, drug testing programs, DNA sampling programs, and data collection-they should have to engage in notice-and-comment rulemaking or a similar democratically …

The Post-Riley Search Warrant: Search Protocols And Particularity In Cell Phone Searches, Adam M. Gershowitz

Vanderbilt Law Review

Last year, in Riley v. California, the Supreme Court required police to procure a warrant before searching a cell phone. Unfortunately, the Court's assumption that requiring search warrants would be "simple" and very protective of privacy was overly optimistic. This article reviews lower court decisions in the year since Riley and finds that the search warrant requirement is far less protective than expected. Rather than restricting search warrants to the narrow evidence being sought, some magistrates have issued expansive warrants authorizing a search of the entire contents of the phone with no restrictions whatsoever. Other courts have authorized searches of …

The Emergency Aid Doctrine And 911 Hang-Ups: The Modern General Warrant, Alexander C. Ellman

Vanderbilt Law Review

The phone rings. A 911 dispatcher starts to answer, but the line goes dead. The dispatcher calls back. No one answers. Was it a misdial or a cry for help cut short? Because callers often expect help to arrive when intentionally calling 911, the police respond to the address from which the call likely originated.' Police approach the house and knock on the door. Again, no one answers. There may be an emergency inside, so the police enter the house without a warrant and without consent. If they find a heart attack victim lying on the floor, they might save …

Cause To Believe What? The Importance Of Defining A Search's Object--Or, How The Aba Would Analyze The Nsa Metadata Surveillance Program, Christopher Slobogin

Vanderbilt Law School Faculty Publications

Courts and scholars have devoted considerable attention to the definition of probable cause and reasonable suspicion. Since the demise of the mere evidence rule in the 1960s, however, they have rarely examined how these central Fourth Amendment concepts interact with the object of the search. That is unfortunate, because this interaction can have significant consequences. For instance, probable cause to believe that a search might lead to evidence of wrongdoing triggers a very different inquiry than probable cause to believe that a search will produce evidence of criminal activity. The failure to address the constraints that should be imposed on …

The Fourth Amendment's National Security Exception: Its History And Limits, L. Rush Atkinson

Vanderbilt Law Review

Since 2001, federal prosecutors have indicted and convicted hundreds of defendants for terrorism, espionage, and other national security crimes.' And for every prosecution, there are dozens of investigations into foreign threats that never result in a trial. Between 2001 and 2010, for example, the federal government obtained 16,306 foreign intelligence warrants in the course of its security operations. Between 2004 and 2011, the Federal Bureau of Investigations ("FBI") issued 119,192 National Security Letters for records deemed to be pertinent to national security investigations.

Despite these numbers, security investigations and prosecutions proceed on uncertain constitutional footing. The rights of terrorism suspects …

Life On Streets And Trails: Fourth Amendment Rights For The Homeless And The Homeward Bound, Wesley C. Jackson

Vanderbilt Law Review

People who read law review articles usually have the resources to temporarily abscond from society on a whim, perhaps to the nearest trailhead, and begin a trek through the woods. Such readers, if they choose a well-maintained trail frequented by long-distance hikers, may come across a simple, three-sided cabin known as a shelter. There they might find a grimy and unwashed bunch, talking amongst themselves using jargon such as "blazes" and "trail angels." Some may recognize them as "thru-hikers" and wonder how long the scrawny, bearded, and overloaded travelers have been at it. But some may ask if these apparent …

The Exclusionary Rule: Is It On Its Way Out? Should It Be?, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This symposium, comprising six articles in addition to this one, was triggered by a spate of Supreme Court opinions occurring over the last seven years, all of which raise the two questions in the title to this article (which is also the title of the symposium). Since 1974, when United States v. Calandra definitively established deterrence as the primary objective of the suppression remedy, the Court has nibbled away at the exclusionary rule from a number of different directions. But the Court's decisions in Hudson v. Michigan (2006), Herring v. United States (2009), and Davis v. United States (2011) reveal …

Looking For Trouble: An Exploration Of How To Regulate Digital Searches, Eric Yeager

Vanderbilt Law Review

Imagine that the cybercrime division of a local police force receives a report of fraudulent credit card purchases, and after linking subpoenaed credit card records to a particular shipping address, officers obtain a warrant to search the computer of the resident for evidence of identity theft and fraud. During a preliminary search of the suspect's hard drive, the investigators discover a folder marked "preteen porno pix" filled entirely with picture and video files. Knowing that the evidence they are looking for is almost certainly contained within a text file, they have little reason to believe that opening this folder will …

What Is The Essential Fourth Amendment?, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In More Essential Than Ever: The Fourth Amendment in the Twenty-First Century, Stephen Schulhofer provides a strong, popularized brief for interpreting the Fourth Amendment as a command that judicial review precede all non-exigent police investigative actions that are more than minimally intrusive. This review points out a few places where Schulhofer may push the envelope too far or not far enough, but concludes that More Essential Than Ever is a welcome reminder for scholars and the public at large that the Fourth Amendment is a fundamental bulwark of constitutional jurisprudence and deserves more respect than the Supreme Court has given …

Rehnquist And Panvasive Searches, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In the history of the Supreme Court, William Rehnquist may have been the least friendly justice toward the view that the Fourth Amendment should be read expansively. Even he, however, might have interpreted the amendment to place more restrictions on modern law enforcement techniques than current caselaw does. Relying on a 1974 article authored by Rehnquist, this essay, written for a symposium on Rehnquist and the Fourth Amendment, describes his views on the types of requirements the Fourth Amendment imposes on the police, how decriminalization can protect privacy, and most importantly, why Rehnquist might have been willing to regulate surveillance …

Constitutional Cacophony: Federal Circuit Splits And The Fourth Amendment, Wayne A. Logan

Vanderbilt Law Review

Despite their many differences, Americans have long been bound by a shared sense of constitutional commonality. Federal constitutional rights, however, can and do often vary based on geographic location, and a chief source of this variation stems from an unexpected origin: the nation's federal circuit courts of appeals. While a rich literature exists on federal circuit splits in general, this Article provides the first empirical study of federal constitutional law circuit splits. Focusing on Fourth Amendment doctrine in particular, the Article highlights the existence of over three dozen current circuit splits, which result in the unequal allocation of liberty and …

Making The Most Of United States V. Jones In A Surveillance Society: A Statutory Implementation Of Mosaic Theory, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In the Supreme Court's recent decision in United States v. Jones, a majority of the Justices appeared to recognize that under some circumstances aggregation of information about an individual through governmental surveillance can amount to a Fourth Amendment search. If adopted by the Court, this notion sometimes called "mosaic theory"-could bring about a radical change to Fourth Amendment jurisprudence, not just in connection with surveillance of public movements-the issue raised in Jonesbut also with respect to the government's increasingly pervasive record-mining efforts. One reason the Court might avoid the mosaic theory is the perceived difficulty of implementing it. This article …

Virtual Blinds: Finding Online Privacy In Offline Precedents, Allyson W. Haynes

Vanderbilt Journal of Entertainment & Technology Law

A person in a building shows a desire for privacy by pulling her blinds shut or closing her curtains. Otherwise, she cannot complain when her neighbor sees her undressing from the window, or when a policeman looks up from the street and sees her marijuana plants. In the online context, can we find an analogy to these privacy blinds? Or is the window legally bare because of the nature of the Internet?

This Article argues that by analyzing the privacy given to communications in the offline context, and in particular, by analyzing case law recognizing privacy in an otherwise public …

Cloudy Privacy Protections: Why The Stored Communications Act Fails To Protect The Privacy Of Communications Stored In The Cloud, Ilana R. Kattan

Vanderbilt Journal of Entertainment & Technology Law

The advent of new communications technologies has generated debate over the applicability of the Fourth Amendment's warrant requirement to communications sent through, and stored in, technologies not anticipated by the Framers. In 1986, Congress responded to perceived gaps in the protections of the warrant requirement as applied to newer technologies, such as email, by passing the Stored Communications Act (SCA). As originally enacted, the SCA attempted to balance the interests of law enforcement against individual privacy rights by dictating the mechanisms by which the government could compel a particular service provider to disclose communications stored on behalf of its customers. …

Some Hypotheses About Empirical Desert, Christopher Slobogin

Vanderbilt Law School Faculty Publications

Paul Robinson has written a series of articles advocating the view that empirical desert should govern development of criminal law doctrine. The central contention of empirical desert is that adherence to societal views of justice“ defined in terms of moral blameworthiness will not only satisfy retributive urges, but will also often be as efficacious at controlling crime as a system that revolves around other utilitarian purposes of punishment. Constructing criminal laws that implement empirical desert has the latter effect, Robinson argues, because it enhances the moral credibility of the law, thus minimizing citizens desire to engage in vigilantism and other …

Along For The Ride: Gps And The Fourth Amendment, Stephen A. Josey

Vanderbilt Journal of Entertainment & Technology Law

With the advent of new technologies, the line as to where the Fourth Amendment forbids certain police behavior and when it does not has become increasingly blurred. Recently, the issue of whether police may use Global Positioning System (GPS) tracking devices to track individuals for prolonged periods of time without first securing a search warrant has crept its way into the limelight. The various circuits have arrived at different conclusions, and the question has now found its way onto the US Supreme Court's docket. After analyzing and weighing both Supreme Court case law and public policy considerations, this Note concludes …

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 …
