The Positive Law Model Of The Fourth Amendment, William Baude, James Y. Stern

James Y. Stern

For fifty years, courts have used a “reasonable expectation of privacy” standard to define “searches” under the Fourth Amendment. As others have recognized, that doctrine is subjective, unpredictable, and conceptually confused, but viable alternatives have been slow to emerge. This Article supplies one.

We argue that Fourth Amendment protection should be anchored in background positive law. The touchstone of the search-and-seizure analysis should be whether government officials have done something forbidden to private parties. It is those actions that should be subjected to Fourth Amendment reasonableness review and the presumptive requirement to obtain a warrant. In short, Fourth Amendment protection …

The Right To Remain Armed, Jeffrey Bellin

Jeffrey Bellin

The laws governing gun possession are changing rapidly. In the past two years, federal courts have wielded a revitalized Second Amendment to invalidate longstanding gun carrying restrictions in Chicago, the District of Columbia, and throughout California. Invoking similar Second Amendment themes, legislators across the country have steadily deregulated public gun carrying, preempting municipal gun control ordinances in cities like Philadelphia, Atlanta, and Cleveland.

These changes to substantive gun laws reverberate through the constitutional criminal procedure framework. By making it lawful for citizens to carry guns even in crowded urban areas, enhanced Second Amendment rights trigger Fourth Amendment protections that could …

The Inverse Relationship Between The Constitutionality And Effectiveness Of New York City "Stop And Frisk", Jeffrey Bellin

Jeffrey Bellin

New York City sits at the epicenter of an extraordinary criminal justice phenomenon. While employing aggressive policing tactics, such as “stop and frisk,” on an unprecedented scale, the City dramatically reduced both violent crime and incarceration – with the connections between these developments (if any) hotly disputed. Further clouding the picture, in August 2013, a federal district court ruled the City’s heavy reliance on “stop and frisk” unconstitutional. Popular and academic commentary generally highlights isolated pieces of this complex story, constructing an incomplete vision of the lessons to be drawn from the New York experience. This Article brings together all …

Crime-Severity Distinctions And The Fourth Amendment: Reassessing Reasonableness In A Changing World, Jeffrey Bellin

Jeffrey Bellin

A growing body of commentary calls for the Supreme Court to recalibrate its Fourth Amendment jurisprudence in response to technological and social changes that threaten the traditional balance between public safety and personal liberty. This Article joins the discussion, highlighting a largely overlooked consideration that should be included in any modernization of Fourth Amendment doctrine—crime severity.

The Supreme Court emphasizes that “reasonableness” is the “touchstone” of Fourth Amendment analysis. Yet, in evaluating contested searches and seizures, current Fourth Amendment doctrine ignores a key determinant of reasonableness, the crime under investigation. As a result, an invasive search of a suspected murderer …

The Iphone Meets The Fourth Amendment, Adam M. Gershowitz

Adam M. Gershowitz

Under the search incident to arrest doctrine, police may search the entire body and immediate grabbing space of an arrestee, including the contents of all containers, without any probable cause. Because almost all traffic infractions are arrestable offenses, police have enormous opportunity to conduct such searches incident to arrest. In the near future, these already high-stakes searches will become even more important because millions of drivers will not only possess containers that hold a few scattered papers, such as wallets or briefcases, but also iPhones—capable of holding tens of thousands of pages of personal information. If current Fourth Amendment jurisprudence …

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

Adam M. Gershowitz

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 …

Texting While Driving Meets The Fourth Amendment: Deterring Both Texting And Warrantless Cell Phone Searches, Adam M. Gershowitz

Adam M. Gershowitz

Recent laws criminalizing texting while driving are under-inclusive, ambiguous, and impose light punishments that are unlikely to deter. At the same time, the laws empower police to conduct warrantless searches of drivers’ cell phones. Texting while driving is dangerous and should be punished with stiff fines, possible jail time, license suspensions, and interlock devices that prevent use of phones while driving. However, more severe punishment will not eliminate police authority to conduct warrantless cell phone searches. This Article therefore proposes that legislatures allow drivers to immediately confess to texting while driving in exchange for avoiding a search of their phones. …

Heien'S Mistake Of Law, Kit Kinports

Kit Kinports

The Supreme Court has been whittling away at the Fourth Amendment for decades. The Court's 2014 ruling in Heien v. North Carolina allowing the police to make a traffic stop based on a reasonable mistake of law generated little controversy among the Justices and escaped largely unnoticed by the press-perhaps because yet another Supreme Court decision reading the Fourth Amendment narrowly is not especially noteworthy or because the opinion's cursory and overly simplistic analysis equating law enforcement's reasonable mistakes of fact and law minimized the significance of the Court's decision. But the temptation to dismiss Heien as just another small …

Self Incrimination And Cryptographic Keys, Gregory S. Sergienko

Greg Sergienko

Modern cryptography can make it virtually impossible to decipher documents without the cryptographic key thus making the availability of the contents of those documents depend on the availability of the key. This article examines the Fourth and Fifth Amendments' protection against the compulsory production of the key and the scope of the Fifth Amendment immunity against compelled production. After analyzing these questions using prevailing Fourth and Fifth Amendment jurisprudence, I shall describe the advantages of a privacy-based approach in practical and constitutional terms.

Stubbornness Of Pretexts, Daniel B. Yeager

Daniel B. Yeager

This Article will reflect on (1) how the Whren v. United States failure to acknowledge what counts as a pretext accounts for the residual confusion as to whether or not Whren really has killed off the pretext argument in constitutional criminal procedure, and (2) the extent to which the Court in Sullivan compounded that failure, which I hope to lightly correct here by distinguishing motives from intentions and then by elaborating the role that each plays, or at least should play, in Fourth Amendment jurisprudence.

Overcoming Hiddenness: The Role Of Intentions In Fourth Amendment Analysis, Daniel B. Yeager

Daniel B. Yeager

This Article rehearses a response to the problems posed to and by the Supreme Court's attempts to work out the meaning and operation of the word "search." After commencing Part II by meditating on the notion of privacy, I take up its relation to the antecedent suspicion or knowledge that Fourth-Amendment law requires as a justification for all privacy invasions. From there, I look specifically at that uneasy relation in Supreme Court jurisprudence, which has come to privilege privacy over property as a Fourth Amendment value. From there, Part III reviews the sources or bases that can tell us what …

The Rhetoric Of The Fourth Amendment: Toward A More Persuasive Fourth Amendment, Timothy C. Macdonnell

Timothy C. MacDonnell

In the last forty-five years, the United States Supreme Court’s jurisprudence through the lens of classical rhetoric. Opinions are assessed based on three areas of persuasion: appeals to logic (logos); appeals to emotion (pathos); and appeals to credibility (ethos). By examining the Justices’ opinions in this fashion, patterns of unpersuasive opinion writing emerge. While a common source for all unpersuasive opinions is not available, common patterns of weak persuasion in particular appeals do exist. Weak appeals to ethos commonly stem from Justices failing to fully confront the doctrine of stare decisis. Weak pathos-based appeals often involve Justices engaging in misplaced …

Fourth Amendment Remedies As Rights: The Warrant Requirement, David Gray

David C. Gray

The constitutional status of the warrant requirement is hotly debated. Critics argue that neither the text nor history of the Fourth Amendment support a warrant requirement. Also questioned is the warrant requirement’s ability to protect Fourth Amendment interests. Perhaps in response to these concerns, the Court has steadily degraded the warrant requirement through a series of widening exceptions. The result is an unsatisfying jurisprudence that fails on both conceptual and practical grounds.

These debates have gained new salience with the emergence of modern surveillance technologies such as stingrays, GPS tracking, drones, and Big Data. Although a majority of the Court …

The Supreme Court's Quiet Expansion Of Qualified Immunity, Kit Kinports

Kit Kinports

This Essay discusses the Supreme Court’s tendency in recent opinions to covertly expand the reach of the qualified immunity defense available to public officials in § 1983 civil rights suits. In particular, the Essay points out that the Court, often in per curiam rulings, has described qualified immunity in increasingly broad terms and has qualified and retreated from its precedents, without offering any explanation or even acknowledging that it is deviating from past practice.In making this claim, I focus on three specific issues: the manner in which the Court characterizes the standard governing the qualified immunity defense; the question whether …

Video Evidence And Summary Judgment: The Procedure Of Scott V. Harris, Howard Wasserman

Howard M Wasserman

In Scott v. Harris (2007), the Supreme Court granted summary judgment on a Fourth Amendment excessive-force claim brought by a motorist injured when a pursuing law-enforcement officer terminated a high-speed pursuit by bumping the plaintiff's car. The Court relied almost exclusively on a video of the chase captured from the officer's dash-mounted camera and disregarded witness testimony that contradicted the video. In granting summary judgment in this circumstance, the Court fell sway to the myth of video evidence as able to speak for itself, as an objective, unambiguous, and singularly accurate depiction of real-world events, not subject to any interpretation …
