Computationally Assessing Suspicion, Wesley M. Oliver, Morgan A. Gray, Jaromir Savelka, Kevin D. Ashley

University of Cincinnati Law Review

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 …

Good Policing Practices Are Difficult, Even For The Avengers, Melanie Reid

Cleveland State Law Review

Policing, as a topic, is complicated. Many have strong views as to what police should or should not be doing and how effectively they are doing it. Too often policing has become polarized with various perspectives disagreeing as to the future of policing. Black Lives Matter, Defund the Police, and Policing Abolition movements are on one spectrum compared to the Blue Lives Matter Movement or other mayoral or police union initiatives. This is clearly a time to collaborate and learn from the various perspectives to bring hope and change in the future. Lawyers, academics, community members, and police officers alike …

The Post-Dobbs Reality: Privacy Expectations For Period-Tracking Apps In Criminal Abortion Prosecutions, Sophie L. Nelson

Pepperdine Law Review

The Supreme Court’s decision to overturn Roe v. Wade and Planned Parenthood v. Casey in June 2022 was met with waves of both support and criticism throughout the United States. Several states immediately implemented or began drafting trigger laws that criminalize seeking and providing an abortion. These laws prompted several period-tracking app companies to encrypt their users’ data to make it more difficult for the government to access period- and pregnancy-related information for criminal investigations. This Comment explores whether the Fourth Amendment and U.S. privacy statutes protect users of period-tracking apps from government surveillance. More specifically, this Comment argues that …

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 …

Intellectual Property And The Myth Of Nonrivalry, James Y. Stern

Notre Dame Law Review

The concept of rivalry is central to modern accounts of property. When one per-son’s use of a resource is incompatible with another’s, a system of rights to determine its use may be necessary. It is commonly asserted, however, that informational goods like inventions and expressive works are nonrivalrous and that intellectual property rights must therefore be subject to special limitation, if they should even exist at all. This Article examines the idea of rivalry more closely and makes a series of claims about the analysis of rivalrousness for purposes of such arguments. Within that frame-work, it argues that rivalry should …

Barcoding Bodies: Rfid Technology And The Perils Of E-Carceration, Jackson Samples

Duke Law & Technology Review

Electronic surveillance now plays a central role in the criminal legal system. Every year, hundreds of thousands of people are tracked by ankle monitors and smartphone technology. And frighteningly, commentators and policymakers have now proposed implanting radio frequency identification (“RFID”) chips into people’s bodies for surveillance purposes. This Note examines the unique risks of these proposals—particularly with respect to people on probation and parole—and argues that RFID implants would constitute a systematic violation of individual privacy and bodily integrity. As a result, they would also violate the Fourth Amendment.

Skirting The Fourth Amendment: How Law Enforcement Agencies Abuse Technology And Constitutional Exceptions To Surveille The Public, Matthew Lloyd

Washington and Lee Journal of Civil Rights and Social Justice

Existing Fourth Amendment law does not protect against law enforcement use of data gathered through the internet either by private companies who actively search their customer’s data and submit evidence of misconduct to law enforcement or from private companies who acquire the data on behalf of law enforcement. In an effort to pursue criminals, courts have permitted Fourth Amendment jurisprudence to develop in a manner that permits sweeping invasions of privacy without any probable cause through the private search doctrine or without any procedural protections through the third-party doctrine. It will require substantial judicial or legislative action to return the …

Circumventing The Fourth Amendment: The Unconstitutional Nature Of Geofence Warrants, Shelby Stender

Utah Law Review

Federal and state law enforcement agencies are using a new tactic for gathering evidence: geofence warrants. These warrants allow law enforcement to gather historical location data collected by third party companies including Google, Facebook, Amazon, and Apple. Armed with a geofence warrant today, law enforcement agencies can track the previous location of an individual at any point from the moment they acquired a cell phone—so long as the location history is turned on. The tactic has grown in popularity since 2019 and has been used to uncover suspects in cases where police had few leads. Troublingly though, the tactic has …

Big Data Searches And The Future Of Criminal Procedure, Mary Fan

Articles

This Article proceeds in three parts. Part I illuminates the nostalgic Luddism that influences Fourth Amendment jurisprudence and the challenges posed by evolving technologies to this dominant lens. This Part explains the operation of geofence and keyword warrants and how their power to crack cold cases by unidentified perpetrators both tempt and terrify. The confusion in the courts over the constitutionality of geofence and keyword warrants is emblematic of the larger challenges of the Romantic Luddism in Fourth Amendment originalism that has grown in influence over the decades.

Part II frames and theorizes the concepts of collateral impact and collateral …

Ohio’S Failure To Protect Motorcyclists' Heads: A Law Enforcement Perspective, B. Thomas

Et Cetera

As a former police officer, the aftereffects of helmetless motorcycle crashes will forever haunt me. This Article discusses the need for helmet laws for all motorcyclists.

Filling The Potholes Of Pretextual Traffic Stops: A Better Road Forward For Ohio, Jordan Weeks

Cleveland State Law Review

The Fourth Amendment was one of the driving forces behind the United States Revolution. This Amendment generally protects individuals against “unreasonable” searches and seizures. But what does “reasonable” mean in the context of a traffic stop?

In 1996, the U.S. Supreme Court in Whren v. United States tried answering this question. In so doing, the Court determined that pretextual traffic stops are “reasonable.” Pretextual traffic stops occur where an officer stops a vehicle and cites a lawful reason for the stop, yet the underlying reason is unlawful. The Whren Court determined that an officer’s intent is completely irrelevant to whether …

Arrests: Legal And Illegal, Daniel Yeager

Georgia State University Law Review

The Fourth Amendment prohibits unreasonable searches and seizures. An arrest—manifesting a police intention to transport a suspect to the stationhouse for booking, fingerprinting, and photographing—is a mode of seizure. Because arrests are so intrusive, they require roughly a fifty percent chance that an arrestable offense has occurred. Because nonarrest seizures (aka Terry stops), though no “petty indignity,” are less intrusive than arrests, they require roughly just a twenty-five percent chance that crime is afoot.

Any arrest not supported by probable cause is illegal. It would therefore seem to follow that any arrest supported by probable cause is legal. But it …

Eavesdropping, The Fourth Amendment, And The Common Law (Of Eavesdropping), Donald A. Dripps

William & Mary Bill of Rights Journal

This Article addresses two of the most momentous and controversial issues raised by the Fourth Amendment. These issues are closely related but distinct. First, is eavesdropping a “search” subject to the Fourth Amendment? Second, are Fourth Amendment “searches” limited to the interests against physical intrusion protected by the common-law torts of trespass and false arrest?

[...]

Remarkably, the debate about the Fourth Amendment, the common law, and eavesdropping has almost completely ignored the common law of eavesdropping. This Article is the first to consider the Fourth Amendment in light of an in-depth examination of the common law’s prohibition of …

If Black Lives Really Matter, We Must End Traffic Stops!, Kenneth Williams

William & Mary Journal of Race, Gender, and Social Justice

This Article will argue that African Americans will continue to be fatally shot and killed by police disproportionately and in many cases unjustifiably as long as police are allowed to stop motorists for minor non-violent traffic infractions. These stops do little to combat crime and are not worth the lives they upend and the continued unconstitutional racial discrimination that motivates many of these stops. Although the standards for police use of force need to be reformed and police culture has to be changed, the other reform that is imperative in order to significantly reduce the disproportionate fatal police shootings of …

The Automated Fourth Amendment, Maneka Sinha

Faculty Scholarship

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 …

Unshielded: How The Police Can Become Touchable, Brandon Hasbrouck

Scholarly Articles

This Review proceeds in three Parts. First, Part I examines Shielded’s text, highlighting Schwartz’s analysis of the problem of unaccountable police, the many barriers to holding police accountable, and her proposed solutions. Part II then critically examines Schwartz’s work, examining pieces of the problem she left undiscussed and the relative shortcomings of her discussion of possible solutions. Finally, Part III takes an abolitionist approach, delving into potential nonreformist reforms and the solution of full abolition, as well as examining the most significant objection to abolitionist approaches: the problem of violence.

Crowdsourcing Surveillance, Chaz Arnett

Faculty Scholarship

In Unreasonable: Black Lives, Police Power, and the Fourth Amendment, Devon W. Carbado illuminates how both the spectacular and quotidian forms of racialized terror, brutality, and surveillance—characteristic of enslavement—have shaped the construction of our constitutional order. He argues that the combined social normalization and legal naturalization of racial hierarchy paved the way for the development of slave patrols and other early iterations of policing where incredible acts of violence against Black bodies were made ordinary and essential. He explains how this legacy continues today with Fourth Amendment jurisprudence not simply failing to protect rights but rather licensing police violence …

Henderson And The Objective Observer Standard: The Future Of Race-Conscious Standards Post-Students For Fair Admissions, Gabriela Dionisio

Seattle University Law Review

On June 29, 2023, the Supreme Court of the United States decided Students for Fair Admissions v. President & Fellows of Harvard College, which struck down race-conscious admissions policies. Within just a year after its ruling, Students for Fair Admissions has already had a sweeping impact, reaching beyond higher education. Although the Supreme Court did not indicate whether Students for Fair Admissions applies to sectors beyond higher education, law firms, and other employers have already modified their diversity policies and initiatives, erasing race and company diversity considerations. Given those dramatic changes, there is growing fear that Students for Fair Admissions …
