Pretrial Commitment And The Fourth Amendment, Laurent Sacharoff

Notre Dame Law Review

Today, the Fourth Amendment Warrant Clause governs arrest warrants and search warrants only. But in the founding era, the Warrant Clause governed a third type of warrant: the “warrant of commitment.” Judges issued these warrants to jail defendants pending trial. This Article argues that the Fourth Amendment Warrant Clause, with its oath and probable cause standard, should be understood today to apply to this third type of warrant. That means the Warrant Clause would govern any initial appearance where a judge first commits a defendant—a process that currently falls far short of fulfilling its constitutional and historical function. History supports …

The Automated Fourth Amendment, Maneka Sinha

Emory Law Journal

Courts routinely defer to police officer judgments in reasonable suspicion and probable cause determinations. Increasingly, though, police officers outsource these threshold judgments to new forms of technology that purport to predict and detect crime and identify those responsible. These policing technologies automate core police determinations about whether crime is occurring and who is responsible.

Criminal procedure doctrine has failed to insist on some level of scrutiny of—or skepticism about—the reliability of this technology. Through an original study analyzing numerous state and federal court opinions, this Article exposes the implications of law enforcement’s reliance on these practices given the weighty interests …

Crimes Of Suspicion, Lauryn P. Gouldin

Emory Law Journal

Requiring that officers have suspicion of specific crimes before they seize people during stops or arrests is a fundamental rule-of-law limitation on government power. Until very recently, the Supreme Court studiously avoided saying whether reasonable suspicion for street and traffic stops must be crime specific, and lower courts are sharply divided as a result. Statements made in Kansas v. Glover that the Fourth Amendment requires reasonable suspicion of a “particular crime” or of “specific criminal activity” may reflect an effort to rehabilitate this foundational principle, but crime specificity was not the Court’s focus in Glover. Meanwhile, Fourth Amendment scholars, even …

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 …

The Computer Got It Wrong: Facial Recognition Technology And Establishing Probable Cause To Arrest, T.J. Benedict

Washington and Lee Law Review

Facial recognition technology (FRT) is a popular tool among police, who use it to identify suspects using photographs or still-images from videos. The technology is far from perfect. Recent studies highlight that many FRT systems are less effective at identifying people of color, women, older people, and children. These race, gender, and age biases arise because FRT is often “trained” using non-diverse faces. As a result, police have wrongfully arrested Black men based on mistaken FRT identifications. This Note explores the intersection of facial recognition technology and probable cause to arrest.

Courts rarely, if ever, examine FRT’s role in establishing …

Border Searches For Investigatory Purposes: Implementing A Border Nexus Standard, Brenna Ferris

University of Michigan Journal of Law Reform Caveat

Border searches are a commonly used exception to the Fourth Amendment’s probable cause and warrant requirements. Using a border search, the government can conduct searches of individuals without any kind of individualized suspicion. Border searches pose a concerning risk to privacy when they are used as a tool for criminal investigations. The Supreme Court has never ruled on searches used in this way, but lower courts are addressing the technique and reaching conflicting decisions. Courts need to take an approach that will protect the privacy interests of individuals while allowing the government to advance its interests in protecting its borders …

Revising Reasonableness In The Cloud, Ian Walsh

Washington Law Review

Save everything—just in case––and search for it later. This is a modern mantra fueled by the ubiquity of smartphones, laptops, tablets, and free or low-cost data storage that leads users to store massive amounts of data in the cloud. But when users trust third-party cloud storage providers with private communications, they also surrender Fourth Amendment constitutional certainty. Existing statutory safeguards for these communications are lower than Fourth Amendment warrant and probable cause standards; this permits the government to seize large quantities of users’ private communications stored in the cloud with only minimal justification. Due to the revealing nature of such …

Let's Make Some "Scents" Of Our Fourth Amendment Rights: The Discriminatory Truths Behind Using The Mere Smell Of Burnt Marijuana As Probable Cause To Search A Vehicle, Alessandra Dumenigo

St. Thomas Law Review

This Comment addresses the negative effects that have resulted and will continue to result if police officers are encouraged by jurisprudence to conduct a warrantless search of an entire vehicle based on the smell of burnt marijuana. Warrantless searches of an entire vehicle based merely on the smell of burnt marijuana grant officers unlimited power that will likely result in police misconduct, an increase in racially profiled traffic stops, and a distrust between police officers and the Black community amid the nationwide outrage over the death of George Floyd. Part II of this Comment discusses the history of the Fourth …

Peffer V. Stephens: Probable Cause, Searches And Seizures Within The Home, And Why Using Technology Should Not Open Your Front Door, Shane Landers

Texas A&M Law Review

The Fourth Amendment provides for the right of the people to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures. Search warrants may only be issued upon a finding of probable cause. This core tenet of our constitutional republic becomes progressively flexible with every development in Fourth Amendment interpretation. In Peffer v. Stephens, the United States Court of Appeals for the Sixth Circuit delivered the latest blow to constitutional rights that restrict the State from engaging in unprincipled searches. In an issue of first impression, the Sixth Circuit held that a criminal defendant’s alleged use …

Revitalizing Fourth Amendment Protections: A True Totality Of The Circumstances Test In § 1983 Probable Cause Determinations, Ryan Sullivan

Nebraska College of Law: Faculty Publications

The Article analyzes claims of police misconduct and false arrest, specifically addressing the issue of whether a police officer may ignore evidence of an affirmative defense, such as self-defense, when determining probable cause for an arrest. The inquiry most often arises in § 1983 civil claims for false arrest where the officer was aware of some evidence a crime had been committed, but was also aware of facts indicating the suspect had an affirmative defense to the crime observed. In extreme cases, the affirmative defense at issue is actually self-defense in response to the officer’s own unlawful conduct. As police …

Saving America’S Privacy Rights: Why Carpenter V. United States Was Wrongly Decided And Why Courts Should Be Promoting Legislative Reform Rather Than Extending Existing Privacy Jurisprudence, David Stone

St. Mary's Law Journal

Privacy rights are under assault, but the Supreme Court’s judicial intervention into the issue, starting with Katz v. United States and leading to the Carpenter v. United States decision has created an inconsistent, piecemeal common law of privacy that forestalls a systematic public policy resolution by Congress and the states. In order to reach a satisfactory and longlasting resolution of the problem consistent with separation of powers principles, the states should consider a constitutional amendment that reduces the danger of pervasive technologyaided surveillance and monitoring, together with a series of statutes addressing each new issue posed by technological change as …

Cell Phones Are Orwell's Telescreen: The Need For Fourth Amendment Protection In Real-Time Cell Phone Location Information, Matthew Devoy Jones

Cleveland State Law Review

Courts are divided as to whether law enforcement can collect cell phone location information in real-time without a warrant under the Fourth Amendment. This Article argues that Carpenter v. United States requires a warrant under the Fourth Amendment prior to law enforcement’s collection of real-time cell phone location information. Courts that have required a warrant prior to the government’s collection of real-time cell phone location information have considered the length of surveillance. This should not be a factor. The growing prevalence and usage of cell phones and cell phone technology, the original intent of the Fourth Amendment, and United States …

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 …

Forensic Border Searches After Carpenter Require Probable Cause And A Warrant, Christopher I. Pryby

Michigan Law Review

Under the border search doctrine, courts have upheld the federal government's practice of searching people and their possessions upon entry into or exit from the United States, without any requirement of suspicion, as reasonable under the Fourth Amendment. Since the advent of electronic devices with large storage capacities, courts have grappled with whether this definition of reasonableness continues to apply. So far, courts have consistently characterized “nonforensic” border inspections of electronic devices (for example, paging through photos on a phone) as “routine” searches that, like inspecting luggage brought across international lines, require no suspicion. But there is a circuit split …

Whren V. United States: An Abrupt End To The Debate Over Pretextual Stops, Brian J. O'Donnell

Maine Law Review

In Whren v. United States, the United States Supreme Court held that a traffic stop is reasonable under the Fourth Amendment if a police officer has probable cause to believe that a traffic violation has occurred, even if the stop is a pretext for the investigation of a more serious offense. The Court affirmed the convictions of Michael A. Whren and James L. Brown, who had been arrested on federal drug charges after Washington, D.C., police stopped Brown for minor traffic infractions. The Court's unanimous opinion, delivered by Justice Scalia, brought an end to a long-running debate over the proper …

Does The End Justify The Means? The Clumsy And Circuitous Logic Of Blood Test Admissibility In Criminal Prosecutions In State V. Cormier, Kyle T. Macdonald

Maine Law Review

In State v. Cormier, the Maine Supreme Judicial Court, sitting as the Law Court, was asked to determine whether a Maine statute requiring law enforcement officers to test the blood of all drivers for intoxicants following a fatal motor vehicle collision violates the Fourth Amendment of the United States Constitution when the operation of the statute allows for the admission of those blood test results in a future criminal trial of the driver. In determining that the procedures of title 29-A, section 2522 of the Maine Revised Statutes are not violative of the Fourth Amendment, the Law Court effectively confirmed …

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 …

Probable Cause And Reasonable Suspicion: Totality Tests Or Rigid Rules?, Kit Kinports

Kit Kinports

This piece argues that the Supreme Court's April 2014 decision in Navarette v. Calfornia, like last Term's opinion in Florida v. Harris, deviates from longstanding Supreme Court precedent treating probable cause and reasonable suspicion as totality-of-the-circumstances tests. Instead, these two recent rulings essentially rely on rigid rules to define probable cause and reasonable suspicion. The article criticizes the Court for selectively endorsing bright-line tests that favor the prosecution, and argues that both decisions generate rules that oversimplify and therefore tend to be overinclusive.

Camreta And Al-Kidd: The Supreme Court, The Fourth Amendment, And Witnesses, Kit Kinports

Kit Kinports

Although few noticed the link between them, two Supreme Court cases decided in the same week last Term, Ashcroft v. al-Kidd and Camreta v. Greene, both involved the Fourth Amendment implications of detaining witnesses to a crime. Al-Kidd, an American citizen, was arrested under the federal material witness statute in connection with an investigation into terrorist activities, and Greene, a nine-year-old suspected victim of child abuse, was seized and interrogated at school by two state officials. The opinions issued in the two cases did little to resolve the constitutional issues that arise in witness detention cases, and in fact muddied …

What's Fear Got To Do With It?: The "Armed And Dangerous" Requirement Of Terry, Gerald S. Reamey

Marquette Law Review

Rarely has a court’s opinion, even one from the Supreme Court of the United States, so altered existing notions of constitutional criminal procedure law as did the opinion in Terry v. Ohio. On several levels, the opinion dramatically shifted the way in which the Fourth Amendment was understood. Law students who had learned about the probable cause “requirement” and the warrant “requirement” were surprised to learn, especially in the case of the former, that these “requirements” were not required at all. To continue to conceptualize the Fourth Amendment’s single sentence guarantees as consisting of a “warrant clause” and a “reasonableness” …

Arbitrary Law Enforcement Is Unreasonable: Whren's Failure To Hold Police Accountable For Traffic Enforcement Policies, Jonathan Witmer-Rich

Law Faculty Articles and Essays

Whren v. United States is surely a leading contender for the most controversial and heavily criticized Supreme Court case that was decided in a short, unanimous opinion. The slip opinion is only thirteen pages long, and provoked no dissents or even concurring opinions. Critical reaction has been overwhelmingly negative. Criticism not withstanding, the Court has not retreated from Whren, but continues to repeat its core holding.

Part I frames the problem in Whren with a story. Part II sets forth the fundamental Fourth Amendment principle underlying this article—the prohibition against arbitrary search and seizure. Part III explains how arbitrariness …

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, …
