Computationally Assessing Suspicion, Wesley M. Oliver

Law Faculty Publications

Law enforcement officers performing drug interdiction on interstate highways have to decide nearly every day whether there is reasonable suspicion to detain motorists until a trained dog can sniff for the presence of drugs. The officers’ assessments are often wrong, however, and lead to unnecessary detentions of innocent persons and the suppression of drugs found on guilty ones. We propose a computational method of evaluating suspicion in these encounters and offer experimental results from early efforts demonstrating its feasibility. With the assistance of large language and predictive machine learning models, it appears that judges, advocates, and even police officers could …

Searches Without Suspicion: Avoiding A Four Million Person Underclass, Tonja Jacobi, Addie Maguire

Faculty Articles

In Samson v. California, the Supreme Court upheld warrantless, suspicionless searches for parolees. That determination was controversial both because suspicionless searches are, by definition, anathema to the Fourth Amendment, and because they arguably undermine parolees’ rehabilitation. Less attention has been given to the fact that the implications of the case were not limited to parolees. The opinion in Samson included half a sentence of dicta that seemingly swept probationers into its analysis, implicating the rights of millions of additional people in the United States. Not only is analogizing parolees and probationers not logically sound because the two groups differ …

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 …

Rewriting Whren V. United States, Jonathan Feingold, Devon Carbado

Faculty Scholarship

In 1996, the U.S. Supreme Court decided Whren v. United States—a unanimous opinion in which the Court effectively constitutionalized racial profiling. Despite its enduring consequences, Whren remains good law today. This Article rewrites the opinion. We do so, in part, to demonstrate how one might incorporate racial justice concerns into Fourth Amendment jurisprudence, a body of law that has long elided and marginalized the racialized dimensions of policing. A separate aim is to reveal the “false necessity” of the Whren outcome. The fact that Whren was unanimous, and that even progressive Justices signed on, might lead one to conclude that …

Requiring What’S Not Required: Circuit Courts Are Disregarding Supreme Court Precedent And Revisiting Officer Inadvertence In Cyberlaw Cases, Michelle Zakarin

Scholarly Works

As the age of technology has taken this country by surprise and left us with an inability to formally prepare our legal system to incorporate these advances, many courts are forced to adapt by applying pre-technology rules to new technological scenarios. One illustration is the plain view exception to the Fourth Amendment. Recently, the issue of officer inadvertence at the time of the search, a rule that the United States Supreme Court has specifically stated is not required in plain view inquiries, has been revisited in cyber law cases. It could be said that the courts interested in the existence …

Presumed Punishable: Sentencing On The Streets And The Need To Protect Black Lives Through A Reinvigoration Of The Presumption Of Innocence, Jelani Jefferson Exum

Faculty Publications

(Excerpt)

Following the police killing of George Floyd in the summer of 2020, there has been a renewed focus on protecting Black people in America from excessive police violence. While the images of George Floyd were shocking to the public, that level of extreme violence and disregard for life has been a common aspect of the lives of Black Americans throughout history. In America, Black people are "pre­sumed punishable." Due to the historical and persistent biases against Black people, Black people find themselves subject to false assumptions about their criminality and presumptions that they are deserving of punishment. This stands …

The Origins And Legacy Of The Fourth Amendment Reasonableness Balancing Model, Kit Kinports

Journal Articles

The overwhelming majority of the Supreme Court’s Fourth Amendment cases over the past fifty years have been resolved using a warrant presumption model, which determines the constitutionality of a search or seizure by asking whether law enforcement officials had probable cause and a warrant, or some exception to those requirements. But three decisions, beginning in 2001, mysteriously deviated from that approach and applied a reasonableness balancing model, upholding the searches in those cases after considering the totality of the circumstances and weighing the competing government interests against the defendant’s privacy interests. This balancing approach has justifiably been criticized as amorphous, …

The Fourth Amendment Inventory As A Check On Digital Searches, Laurent Sacharoff

Sturm College of Law: Faculty Scholarship

Police and federal agents generally must obtain a warrant to search the tens of thousands of devices they seize each year. But once they have a warrant, courts afford these officers broad leeway to search the entire device, every file and folder, all metadata and deleted data, even if in search of only one incriminating file. Courts avow great reverence for the privacy of personal information under the Fourth Amendment but then claim there is no way to limit where an officer might find the target files, or know where the suspect may have hidden them.

These courts have a …

Functional Equivalence And Residual Rights Post-Carpenter: Framing A Test Consistent With Precedent And Original Meaning, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

The Carpenter Court held that warrantless access to seven or more days of cell site location information (CSLI) constitutes a violation of the reasonable expectation of privacy that individuals have in the whole of their physical movements. But the grounds on which the Court drew a line characterize all sorts of digital records—including those at issue in Miller and Smith, belying the majority’s claim that the decision leaves third-party doctrine intact. Instead of avoiding Katz’s pitfalls, moreover, the Court emphasized voluntary assumption of risk, doubling down on the subjective nature of judicial determination. The decision will likely lead to …

Policing The Prosecutor: Race, The Fourth Amendment, And The Prosecution Of Criminal Cases, Renee Mcdonald Hutchins

Journal Articles

As this article explores, while the Fourth Amendment is commonly criticized for the discretion it affords police officers, an overlooked result of the amendment’s lax regulation of the police is the enhanced power it affords prosecutors. Though for a time a warrant was the notional measure of reasonableness, over the last century the Court has crafted several exceptions to that measure to give the police greater leeway during on-the-street encounters. The Court has concurrently retreated from robust application of the exclusionary rule to remedy constitutional violations. These shifts have meant far more predictable wins for the prosecution at the suppression …

Supreme Irrelevance: The Court’S Abdication In Criminal Procedure Jurisprudence, Tonja Jacobi, Ross Berlin

Faculty Articles

Criminal procedure is one of the Supreme Court’s most active areas of jurisprudence, but the Court’s rulings are largely irrelevant to the actual workings of the criminal justice system. The Court’s irrelevance takes two forms: objectively, on the numbers, its jurisprudence fails to protect the vast majority of people affected by the criminal justice system; and in terms of salience, the Court has sidestepped the major challenges in the United States today relating to the criminal justice system. These challenges include discrimination in stops and frisks, fatal police shootings, unconscionable plea deals, mass incarceration, and disproportionate execution of racial minorities. …

Cybersurveillance Intrusions And An Evolving Katz Privacy Test, Margaret Hu

Scholarly Articles

To contextualize why a new approach to the Fourth Amendment is essential, this Article describes two emerging cybersurveillance tools. The first Cybersurveillance tool, Geofeedia, has been deployed by state and local law enforcement. Geofeedia uses a process known as "geofencing" to draw a virtual barrier around a particular geographic region, and then identifies and tracks public social media posts within that region for predictive policing purposes. The second tool, Future Attribute Screening Technology (FAST), is under development by the United States Department of Homeland Security (DHS). FAST is another predictive policing tool that analyzes physiological and behavioral signals with the …

Terry Stops And Frisks: The Troubling Use Of Common Sense In A World Of Empirical Data, David A. Harris, David Rudovsky

Articles

The investigative detention doctrine first announced in Terry v. Ohio and amplified over the past fifty years has been much analyzed, praised, and criticized from a number of perspectives. Significantly, however, over this time period commentators have only occasionally questioned the Supreme Court’s “common sense” judgments regarding the factors sufficient to establish reasonable suspicion for stops and frisks. For years, the Court has provided no empirical basis for its judgments, due in large part to the lack of reliable data. Now, with the emergence of comprehensive data on these police practices, much can be learned about the predictive power of …

Game Of Drones: Rolling The Dice With Unmanned Aerial Vehicles And Privacy, Rebecca L. Scharf

Scholarly Works

This Article offers a practical three-part test for courts and law enforcement to utilize when faced with drone and privacy issues. Specifically addressing the question: how should courts analyze the Fourth Amendment’s protection against ‘unreasonable searches’ in the context of drones?

The Supreme Court’s Fourth Amendment jurisprudence produced an intricate framework to address issues arising out of the intersection of technology and privacy interests. In prominent decisions, including United States v. Katz, California v. Ciraolo, Kyllo v. United States, and most notably, United States v. Jones, the Court focused on whether the use of a single …

Notice And Standing In The Fourth Amendment: Searches Of Personal Data, Jennifer Daskal

Articles in Law Reviews & Other Academic Journals

In at least two recent cases, courts have rejected service providers' capacity to raise Fourth Amendment claims on behalf of their customers. These holdings rely on longstanding Supreme Court doctrine establishing a general rule against third parties asserting the Fourth Amendment rights of others. However, there is a key difference between these two recent cases and those cases on which the doctrine rests. The relevant Supreme Court doctrine stems from situations in which someone could take action to raise the Fourth Amendment claim, even if the particular thirdparty litigant could not. In the situations presented by the recent cases, by …

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 …

Civil Arrest? (Another) St. Louis Case Study In Unconstitutionality, Mae Quinn, Eirik Cheverud

Journal Articles

This Article advances a simple claim in need of enforcement in this country right now: no person may be arrested for an alleged violation of civil, as opposed to criminal, law. Indeed, courts have long interpreted the Fourth Amendment as prohibiting arrest except when probable cause exists to believe that a crime has been committed and that the defendant is the person who committed the crime. However, in many places police take citizens into custody without a warrant for the non-criminal conduct of allegedly breaking civil laws. This unfortunate phenomenon received national attention in St. Louis, Missouri following the death …

Evidence Laundering In A Post-Herring World, Kay L. Levine, Jenia I. Turner, Ronald F. Wright

Faculty Articles

The Supreme Court’s decision in Herring v. United States authorizes police to defeat the Fourth Amendment’s protections through a process we call evidence laundering. Evidence laundering occurs when one police officer makes a constitutional mistake when gathering evidence and then passes that evidence along to a second officer, who develops it further and then delivers it to prosecutors for use in a criminal case. The original constitutional taint disappears in the wash.

Courts have allowed evidence laundering in a variety of contexts, from cases involving flawed databases to cases stemming from faulty judgments and communication lapses in law enforcement teams. …

Whither Reasonable Suspicion: The Supreme Court's Functional Abandonment Of The Reasonableness Requirement For Fourth Amendment Seizures, Steven P. Grossman

All Faculty Scholarship

Although the United States Supreme Court’s approach to issues governing application of the probable cause requirement of the Fourth Amendment has mutated over the years, at least one aspect of its approach has remained constant. Before information leading to probable cause or its lesser iteration of reasonable suspicion is found to exist, the government must demonstrate in some meaningful way the reliability of the person providing the information or of the information itself. Lacking such reliability, no search or seizure based on probable cause or reasonable suspicion is permitted. In its recent decision in Navarette v. California, the Court largely …

Policing In The Era Of Permissiveness: Mitigating Misconduct Through Third-Party Standing, Julian A. Cook

Scholarly Works

On April 4, 2015, Walter L. Scott was driving his vehicle when he was stopped by Officer Michael T. Slager of the North Charleston, South Carolina, police department for a broken taillight. A dash cam video from the officer’s vehicle showed the two men engaged in what appeared to be a rather routine verbal exchange. Sometime after Slager returned to his vehicle, Scott exited his car and ran away from Slager, prompting the officer to pursue him on foot. After he caught up with Scott in a grassy field near a muffler establishment, a scuffle between the men ensued, purportedly …

Whren's Flawed Assumptions Regarding Race, History, And Unconscious Bias, William M. Carter Jr.

Articles

This article is adapted from remarks presented at CWRU Law School's symposium marking the 20th anniversary of Whren v. United States. The article critiques Whren’s constitutional methodology and evident willful blindness to issues of social psychology, unconscious bias, and the lengthy American history of racialized conceptions of crime and criminalized conceptions of race. The article concludes by suggesting a possible path forward: reconceptualizing racially motivated pretextual police encounters as a badge or incident of slavery under the Thirteenth Amendment issue rather than as abstract Fourth or Fourteenth Amendment issues.

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 …

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.
