Is Your Smartphone Conversation Private? The Stingray Device’S Impact On Privacy In States, Katherine M. Sullivan

Catholic University Law Review

“Where are you” is a common question to receive on your cellphone, but it is up to you whether or not to respond with an answer. No longer does this question need to be asked due to advancements in surveillance technology. When pinpointing a criminal suspect, the question can be answered by local and state agencies, without the person of interest knowing, by using a StingRay device. The main question to be asked is does the conduct of locating a criminal suspect’s exact location without a warrant, violate an individual’s Fourth Amendment Constitutional right to be free from unreasonable searches. …

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 …

Unlocking The Fifth Amendment: Passwords And Encrypted Devices, Laurent Sacharoff

Sturm College of Law: Faculty Scholarship

Each year, law enforcement seizes thousands of electronic devices — smartphones, laptops, and notebooks — that it cannot open without the suspect’s password. Without this password, the information on the device sits completely scrambled behind a wall of encryption. Sometimes agents will be able to obtain the information by hacking, discovering copies of data on the cloud, or obtaining the password voluntarily from the suspects themselves. But when they cannot, may the government compel suspects to disclose or enter their password?

This Article considers the Fifth Amendment protection against compelled disclosures of passwords — a question that has split and …

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. …

The Fourth Amendment In The Age Of Persistent Aerial Surveillance, John Pavletic

Journal of Criminal Law and Criminology

If Big Brother made movies, persistent aerial surveillance would be its masterpiece. Small airplanes are rigged with high-tech cameras that can continuously transmit real-time images to the ground. The aircraft is able to monitor an area of thirty square miles for ten hours at a time. This technology allows video analysts to zoom in and track the location of vehicles, and even people. It was originally designed for military use during the Iraq War, but since then, it has been adapted for civilian applications. In 2016, the Baltimore Police Department contracted with Persistent Surveillance Systems to carry out a trial …

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 …

The Private Search Doctrine And The Evolution Of Fourth Amendment Jurisprudence In The Face Of New Technology: A Broad Or Narrow Exception?, Adam A. Bereston

Catholic University Law Review

The advent of new technology has presented courts with unique challenges when analyzing searches and seizures under the Fourth Amendment. Out of necessity, the application of the Fourth Amendment has evolved to address privacy issues stemming from modern technology that could not have been anticipated by the Amendment’s drafters. As part of this evolution, the Supreme Court devised the “private search” doctrine, which upholds the constitutionality of warrantless police searches of items that were previously searched by a private party, so long as the police search does not exceed the scope of the private-party search. However, courts have struggled to …

Civil Liberty Or National Security: The Battle Over Iphone Encryption, Karen Lowell

Georgia State University Law Review

On June 5, 2013, Edward Snowden released what would be the first of many documents exposing the vast breadth of electronic surveillance the Federal Bureau of Investigation (FBI) and the National Security Agency (NSA) had been conducting on millions of United States citizens. Although the federal agencies had legal authority under the Foreign Intelligence Surveillance Act (FISA) to collect metadata from companies such as Verizon, many Americans considered this data collection to be a massive invasion of privacy.

Equipped with the knowledge of sweeping domestic surveillance programs, citizens and technology firms fighting for strong privacy and security protection, have started …

Knock And Talk No More, Jamesa J. Drake

Maine Law Review

The Supreme Court has set out a roadmap for challenging one of the most common and insidious police tactics used today: the knock-and-talk. The path is short and clear and it leads to the inescapable conclusion that the knock-and-talk—as it is actually employed in practice—is unconstitutional. Although the Court has yet to squarely consider the issue, some Justices have already taken pains to say, in dictum, that knock-and-talks are lawful. Practitioners should not be dissuaded. What this faction of the Court describes is a highly romanticized—and utterly inaccurate—conception of what a knock-and-talk actually entails. The sort of activity that these …

Mass Suppression: Aggregation And The Fourth Amendment, Nirej Sekhon

Georgia Law Review

The FourthAmendment's exclusionary rule requires that
criminal courts suppress evidence obtained as a result of
an unconstitutionalsearch or seizure. The Supreme Court
has repeatedly stated that suppression is purely
regulatory, not remedial. Its only purpose is to deter
future police misconduct, not to remedy past privacy or
liberty harms suffered by the defendant. Exclusion, in
other words, is for the benefit of community members who
might, sometime in the future, be subject to police
misconduct like that endured by the defendant.
Exclusion's regulatory purpose would be greatly aided if
criminal courts could identify when a suppression motion
involved Fourth Amendment …

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

Scholarly Articles in Law Reviews & 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 …

Cops On Trial: Did Fourth Amendment Case Law Help George Zimmerman’S Claim Of Self-Defense?, Josephine Ross

Seattle University Law Review

When police kill unarmed civilians, prosecutors and grand juries often decline to bring criminal charges. Even when police officers are indicted, they are seldom convicted at trial. There are many reasons why police are rarely convicted for violent acts. Commentators have criticized the inherent conflict of interest for prosecutors who decide whether to bring charges and the fact that police are investigating their own. However, this article considers another way that police may be treated differently than other people suspected of committing violent crimes. The Fourth Amendment, designed to protect civilians from overzealous officers, now helps insulate police suspected of …

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. …

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” …

Police Reform And The Judicial Mandate, Julian A. Cook

Scholarly Works

In response to a crisis that threatens his tenure as Mayor of Chicago, Rahm Emanuel announced in December 2015 reform measures designed to curb aggressive police tactics by the Chicago Police Department (CPD). The reform measures are limited, but aim to reduce deadly police-citizen encounters by arming the police with more tasers, and by requiring that officers undergo deescalation training. Though allegations of excessive force have plagued the department for years, the death of Laquan McDonald, an African-American teenager who was fatally shot by Jason Van Dyke, a white officer with the CPD, was the impetus for the Mayor’s reforms. …

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 …

A Domestic Consequence Of The Government Spying On Its Citizens: The Guilty Go Free, Mystica M. Alexander, William P. Wiggins

Brooklyn Law Review

In recent years, a seemingly endless stream of headlines have alerted people to the steady and relentless government encroachment on their civil liberties. Consider, for example, headlines such as “U.S. Directs Agents to Cover Up Program Used to Investigate Americans,” “DEA Admits to Keeping Secret Database of Phone Calls,” or “No Morsel Too Miniscule for All-Consuming N.S.A.” Of concern is not only the U.S. government’s collection of data on its citizens, but also how that information is aggregated, stored, and used. The Fourth Amendment protects citizens from unreasonable searches and seizures by the government. While the drafters of the Fourth …
