Computationally Assessing Suspicion, Wesley M. Oliver May 2024

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 …

Arrests: Legal And Illegal, Daniel Yeager Mar 2024

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 …


Private Police Regulation And The Exclusionary Remedy: How Washington Can Eliminate The Public/Private Distinction, Jared Rothenberg Oct 2023

Private Police Regulation And The Exclusionary Remedy: How Washington Can Eliminate The Public/Private Distinction, Jared Rothenberg

Washington Law Review

Private security forces such as campus police, security guards, loss prevention officers, and the like are not state actors covered by the Fourth Amendment’s prohibition against unreasonable searches and seizures nor the Fifth Amendment’s Miranda protections. As members of the umbrella category of “private police,” these private law enforcement agents often obtain evidence, detain individuals, and elicit confessions in a manner that government actors cannot, which can then be lawfully turned over to the government. Though the same statutory law governing private citizens (assault, false imprisonment, trespass, etc.) also regulates private police conduct, private police conduct is not bound by …


A New Test For The New Crime Exception, Colin Miller May 2023

A New Test For The New Crime Exception, Colin Miller

Utah Law Review

The new crime exception to the Fourth Amendment exclusionary rule allows prosecutors to introduce evidence connected to new crimes committed by defendants who were illegally detained and/or questioned. Unfortunately, as illustrated in this Article, courts largely have applied this new crime exception without any analytical framework or regard for the severity of the initial police misconduct or the defendant’s response. Moreover, courts have begun applying the new crime exception to crimes such as giving a fake name in response to an un-Mirandized interrogation following a lawful arrest.

By doing so, courts have allowed the new crime exception to swallow two …


Gone Fishing: Casting A Wide Net Using Geofence Warrants, Ryan Tursi Mar 2023

Gone Fishing: Casting A Wide Net Using Geofence Warrants, Ryan Tursi

Washington Law Review

Technology companies across the country receive requests from law enforcement agencies for cell phone location information near the scenes of crimes. These requests rely on the traditional warrant process and are known as geofence warrants, or reverse location search warrants. By obtaining location information, law enforcement can identify potential suspects or persons of interest who were near the scene of a crime when they have no leads. But the use of this investigative technique is controversial, as it threatens to intrude upon the privacy of innocent bystanders who had the misfortune of being nearby when the crime took place. Innocent …


Searches Without Suspicion: Avoiding A Four Million Person Underclass, Tonja Jacobi, Addie Maguire Jan 2023

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 Jan 2023

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 Fourth Amendment And The Problem Of Social Cost, Thomas P. Crocker Oct 2022

The Fourth Amendment And The Problem Of Social Cost, Thomas P. Crocker

Northwestern University Law Review

The Supreme Court has made social cost a core concept relevant to the calculation of Fourth Amendment remedies but has never explained the concept’s meaning. The Court limits the availability of both the exclusionary rule and civil damages because of their “substantial social costs.” According to the Court, these costs primarily consist of letting the lawbreaker go free by excluding evidence or deterring effective police practices that would lead to more criminal apprehension and prosecution. But recent calls for systemic police reform by social movements have a different view of social cost. So too do calls for reforming qualified immunity. …


Rewriting Whren V. United States, Jonathan Feingold, Devon Carbado Apr 2022

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 …


The Computer Got It Wrong: Facial Recognition Technology And Establishing Probable Cause To Arrest, T.J. Benedict Apr 2022

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 …


Tech And Authoritarianism: How The People’S Republic Of China Is Using Data To Control Hong Kong And Why The U.S. Is Vulnerable, Bryce Neary Jan 2022

Tech And Authoritarianism: How The People’S Republic Of China Is Using Data To Control Hong Kong And Why The U.S. Is Vulnerable, Bryce Neary

Seattle Journal of Technology, Environmental & Innovation Law

The aim of this article is to analyze and compare current events in the People's Republic of China and the United States to discuss the moral dilemmas that arise when establishing the boundary between national security interests and individual privacy rights. As we continue to intertwine our lives with technology, it has become increasingly important to establish clear privacy rights. The question then becomes: at what point should individuals sacrifice their rights for what the government considers the "greater good" of the country?

Further, this article analyzes the development of U.S. privacy law and its relationship to national security, technology, …


Requiring What’S Not Required: Circuit Courts Are Disregarding Supreme Court Precedent And Revisiting Officer Inadvertence In Cyberlaw Cases, Michelle Zakarin Jan 2022

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 …

Preview—United States V. Cooley: What Will Happen To The Thinnest Blue Line?, Jo J. Phippin

Public Land & Resources Law Review

The Supreme Court of the United States ("Supreme Court") will hear oral arguments in this matter on Tuesday, March 23, 2021. This case presents the narrow issue of whether a tribal police officer has the authority to investigate and detain a non-Indian on a public right-of-way within a reservation for a suspected violation of state or federal law. The lower courts, holding that tribes have no such authority, granted James Cooley’s motion to suppress evidence. The Supreme Court must decide whether the lower courts erred in so deciding. While the issue before the Supreme Court is itself narrow, it has …

School “Safety” Measures Jump Constitutional Guardrails, Maryam Ahranjani Jan 2021

School “Safety” Measures Jump Constitutional Guardrails, Maryam Ahranjani

Seattle University Law Review

In the wake of George Floyd’s murder and efforts to achieve racial justice through systemic reform, this Article argues that widespread “security” measures in public schools, including embedded law enforcement officers, jump constitutional guardrails. These measures must be rethought in light of their negative impact on all children and in favor of more effective—and constitutionally compliant—alternatives to promote school safety. The Black Lives Matter, #DefundthePolice, #abolishthepolice, and #DefundSchoolPolice movements shine a timely and bright spotlight on how the prisonization of public schools leads to the mistreatment of children, particularly children with disabilities, boys, Black and brown children, and low-income children. …


Presumed Punishable: Sentencing On The Streets And The Need To Protect Black Lives Through A Reinvigoration Of The Presumption Of Innocence, Jelani Jefferson Exum Jan 2021

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 …


No Longer Innocent Until Proven Guilty: How Ohio Violates The Fourth Amendment Through Familial Dna Searches Of Felony Arrestees, Jordan Mason Nov 2020

No Longer Innocent Until Proven Guilty: How Ohio Violates The Fourth Amendment Through Familial Dna Searches Of Felony Arrestees, Jordan Mason

Cleveland State Law Review

In 2013, the United States Supreme Court legalized DNA collection of all felony arrestees upon arrest through its decision in Maryland v. King. Since then, the State of Ohio has broadened the use of arrestee DNA by subjecting it to familial DNA searches. Ohio’s practice of conducting familial DNA searches of arrestee DNA violates the Fourth Amendment because arrestees have a reasonable expectation of privacy in the information that is extracted from a familial DNA search and it fails both the totality of the circumstances and the special needs tests. Further, these tests go against the intention of the …


Justice Sonia Sotomayor: The Court’S Premier Defender Of The Fourth Amendment, David L. Hudson Jr. Oct 2020

Justice Sonia Sotomayor: The Court’S Premier Defender Of The Fourth Amendment, David L. Hudson Jr.

Seattle University Law Review

This essay posits that Justice Sotomayor is the Court’s chief defender of the Fourth Amendment and the cherished values it protects. She has consistently defended Fourth Amendment freedoms—in majority, concurring, and especially in dissenting opinions. Part I recounts a few of her majority opinions in Fourth Amendment cases. Part II examines her concurring opinion in United States v. Jones. Part III examines several of her dissenting opinions in Fourth Amendment cases. A review of these opinions demonstrates what should be clear to any observer of the Supreme Court: Justice Sotomayor consistently defends Fourth Amendment principles and values.


Recent Developments, Peyton Hildebrand Aug 2020

Recent Developments, Peyton Hildebrand

Arkansas Law Review

In a 5-4 opinion, the United States Supreme Court once again denied a Bivens action. This case involved a tragic crossborder shooting by a border patrol agent standing on United States soil, who shot and killed a young boy standing on Mexican soil. Petitioners, the boy’s parents, sought relief under Biven2, arguing the agent’s action violated the Constitution. However, the Court determined the cross-border shooting was a new Bivens context, which required an analysis of whether any special factors “counseled hesitation” for the cause of action to be extended. The Court concluded Bivens was inappropriate because several factors “counseled hesitation”—namely, …


The Origins And Legacy Of The Fourth Amendment Reasonableness Balancing Model, Kit Kinports Jan 2020

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 Jan 2020

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 …


Recalibrating Suspicion In An Era Of Hazy Legality, Deborah Ahrens Jan 2020

Recalibrating Suspicion In An Era Of Hazy Legality, Deborah Ahrens

Seattle University Law Review

After a century of employing varying levels of prohibition enforced by criminal law, the United States has entered an era where individual states are rethinking marijuana policy, and the majority of states have in some way decided to make cannabis legally available. This symposium Article will offer a description of what has happened in the past few years, as well as ideas for how jurisdictions can use the changing legal status of cannabis to reshape criminal procedure more broadly. This Article will recommend that law enforcement no longer be permitted use the smell of marijuana as a reason to search …

Cell Phones Are Orwell's Telescreen: The Need For Fourth Amendment Protection In Real-Time Cell Phone Location Information, Matthew Devoy Jones May 2019

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 …

Judges Do It Better: Why Judges Can (And Should) Decide Life Or Death, Andrew R. Ford Jan 2019

Judges Do It Better: Why Judges Can (And Should) Decide Life Or Death, Andrew R. Ford

Dickinson Law Review (2017-Present)

Following its decision in Furman v. Georgia, the Supreme Court of the United States has attempted to standardize procedures that states use to subject offenders to the ultimate penalty. In practice, this attempt at standardization has divided capital sentencing into two distinct parts: the death eligibility decision and the death selection decision. The eligibility decision addresses whether the sentencer may impose the death penalty, while the selection decision determines who among that limited subset of eligible offenders is sentenced to death. In Ring v. Arizona, the Court held for the first time that the Sixth Amendment right to …


Warrantless Searches Of Electronic Devices At U.S. Borders: Securing The Nation Or Violating Digital Liberty?, Ahad Khilji Jan 2019

Warrantless Searches Of Electronic Devices At U.S. Borders: Securing The Nation Or Violating Digital Liberty?, Ahad Khilji

Catholic University Journal of Law and Technology

The steady increase of U.S. citizens traveling with smart phones and other electronic devices has been met with the rise of searches and seizures by CBP officers at U.S borders. Although only less than 0.1% of all travelers may actually be subjected to a search while entering the United States, when comparing the statistics between a six month period in 2016 with the same period in 2017, electronic device searches have almost doubled from 8,383 to 14,993. Approximately one million travelers to the U.S. are inspected by the CBP every day. Out of this population, nearly 2,500 electronic devices are …
