A Cognitive Theory Of The Third-Party Doctrine And Digital Papers, H. Brian Holland

Faculty Scholarship

For nearly 200 years, an individual’s personal papers enjoyed near-absolute protection from government search and seizure. That is no longer the case. With the widespread adoption of cloud-based information processing and storage services, the third-party doctrine operates to effectively strip our digital papers of meaningful Fourth Amendment protections.

This Article presents a new approach to reconciling current third-party doctrine with the technological realities of modern personal information processing. Our most sensitive data is now processed and stored on cloud computing systems owned and operated by third parties. Although we may consider these services to be private and generally secure, the …

Fourth Amendment Protection In The Digital Age, Daniel Sorkin

GGU Law Review Blog

The Supreme Court granted certiorari in Carpenter v United States, a case that offers the Court another opportunity to address how far Fourth Amendment protections against warrantless searches and seizures extend. Specifically, the issue before the Court was “whether the warrantless seizure and search of historical cell phone records revealing the locations and movement of a cell phone user over the course of 127 days is permitted by the Fourth Amendment.”

On appeal before the Sixth Circuit, a divided three-judge panel held that “no search occurred under the Fourth Amendment because Carpenter had no reasonable expectation of privacy in …

Fourth Amendment Constraints On The Technological Monitoring Of Convicted Sex Offenders, Ben A. Mcjunkin, J. J. Prescott

Articles

More than forty U.S. states currently track at least some of their convicted sex offenders using GPS devices. Many offenders will be monitored for life. The burdens and expense of living indefinitely under constant technological monitoring have been well documented, but most commentators have assumed that these burdens were of no constitutional moment because states have characterized such surveillance as ‘‘civil’’ in character—and courts have seemed to agree. In 2015, however, the Supreme Court decided in Grady v. North Carolina that attaching a GPS monitoring device to a person was a Fourth Amendment search, notwithstanding the ostensibly civil character of …

What Caused The 2016 Chicago Homicide Spike? An Empirical Examination Of The 'Aclu Effect' And The Role Of Stop And Frisks In Preventing Gun Violence, Paul Cassell, Richard Fowles

Utah Law Faculty Scholarship

Homicides increased dramatically in Chicago in 2016. In 2015, 480 Chicago residents were killed. The next year, 754 were killed–274 more homicide victims, tragically producing an extraordinary 58% increase in a single year. This article attempts to unravel what happened.

This article provides empirical evidence that the reduction in stop and frisks by the Chicago Police Department beginning around December 2015 was responsible for the homicide spike that started immediately thereafter. The sharp decline in the number of stop and frisks is a strong candidate for the causal factor, particularly since the timing of the homicide spike so perfectly coincides …

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. …

Illegal Predicate Searches And Tainted Warrants After Heien And Strieff, Kit Kinports

Journal Articles

A long-standing debate has surrounded the relationship between two features of the Fourth Amendment's exclusionary rule - the fruits of the poisonous tree doctrine and the good-faith exception - in cases where the evidence used to secure a search warrant was obtained in violation of the defendant's constitutional rights. Some judges and scholars maintain that the fruits of the poisonous tree doctrine takes precedence in such "tainted warrant" cases, leading to the suppression of any evidence seized in executing the warrant unless the warrant was supported by probable cause independent of the illegal predicate search. By contrast, others believe that …

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 …

Bulk Biometric Metadata Collection, Margaret Hu

Scholarly Articles

Smart police body cameras and smart glasses worn by law enforcement increasingly reflect state-of-the-art surveillance technology, such as the integration of live-streaming video with facial recognition and artificial intelligence tools, including automated analytics. This Article explores how these emerging cybersurveillance technologies risk the potential for bulk biometric metadata collection. Such collection is likely to fall outside the scope of the types of bulk metadata collection protections regulated by the USA FREEDOM Act of 2015. The USA FREEDOM Act was intended to bring the practice of bulk telephony metadata collection conducted by the National Security Agency (“NSA”) under tighter regulation. In …

Why Courts Fail To Protect Privacy: Race, Age, Bias, And Technology, Bernard Chao, Catherine Durso, Ian Farrell, Christopher Robertson

Sturm College of Law: Faculty Scholarship

The Fourth Amendment protects against unreasonable “searches and seizures,” but in the digital age of stingray devices and IP tracking, what constitutes a search or seizure? The Supreme Court has held that the threshold question depends on and reflects the “reasonable expectations” of ordinary members of the public concerning their own privacy. For example, the police now exploit the “third party” doctrine to access data held by email and cell phone providers, without securing a warrant, on the Supreme Court’s intuition that the public has no expectation of privacy in that information. Is that assumption correct? If judges’ intuitions about …

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 …

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 …

Body Cameras And The Path To Redeem Privacy Law, Woodrow Hartzog

Faculty Scholarship

From a privacy perspective, the movement towards police body cameras seems ominous. The prospect of a surveillance device capturing massive amounts of data concerning people’s most vulnerable moments is daunting. These concerns are compounded by the fact that there is little consensus and few hard rules on how and for whom these systems should be built and used. But in many ways, this blank slate is a gift. Law and policy makers are not burdened by the weight of rules and technologies created in a different time for a different purpose. These surveillance and data technologies will be modern. Many …

A Genealogy Of Programmatic Stop And Frisk: A Discourse-To-Practice-Circuit, Frank Rudy Cooper

Scholarly Works

President Trump has called for increased use of the recently predominant policing methodology known as programmatic stop and frisk. This Article contributes to the field by identifying, defining, and discussing five key components of the practice: (1) administratively dictated (2) pervasive Terry v. Ohio stops and frisks (3) aimed at crime prevention by means of (4) data-enhanced profiles of suspects that (5) target young racial minority men. Whereas some scholars see programmatic stop and frisk as solely the product of individual police officer bias, this Article argues for understanding how we arrived at specific police practices by analyzing three levels …

Policing Narrative, Tal Kastner

Scholarly Works

Counter narrative, a story that calls attention to and rebuts the presumptions of a dominant narrative framework, functions as an essential tool to reshape the bounds of the law. It has the potential to shape the collective notion of what constitutes legal authority. Black Lives Matter offers a counter narrative that challenges the characterization of the shared public space, among other aspects of contemporary society, as the space of law. Using the concept of necropower--the mobilization and prioritization of the state's power to kill--I analyze the contested physical and conceptual space of law exposed by the counter narrative of Black …

Byrd V United States: Unauthorized Drivers Of Rental Cars Have Fourth Amendment Rights? Not As Evident As It Seems, Tracey Maclin

UF Law Faculty Publications

No discerning student of the Supreme Court would contend that Justice Anthony Kennedy broadly interpreted the Fourth Amendment during his thirty years on the Court. His majority opinions in Maryland v. King, Drayton v. United States and his willingness to join the three key sections of Justice Scalia’s opinion in Hudson v. Maryland, which held that suppression is never a remedy for knock-and-announce violations, are just a few examples of Justice Kennedy’s narrow view of the Fourth Amendment. In light of his previous votes in search and seizure cases, surprisingly Justice Kennedy, in what would be his final Fourth Amendment …

Martin Luther King Jr. And Pretext Stops (And Arrests): Reflections On How Far We Have Not Come Fifty Years Later, Tracey Maclin, Maria Savarese

UF Law Faculty Publications

By January, 1956, the Montgomery Bus boycott was in full-swing. Black citizens in Montgomery, Alabama were refusing to ride the city’s private buses to protest racially segregated seating. On the afternoon of January 26, 1956, twenty-seven-year-old Martin Luther King, Jr. had finished his day of work at the Dexter Avenue Baptist Church in Montgomery. On his drive home, King stopped his vehicle to offer a ride to a group of bus boycotters standing at a downtown car-pool location. After the boycotters entered King’s car, two motorcycle policemen pulled-in behind King’s vehicle. While everyone in King’s car tried to remain calm, …
