Washington Search And Seizure Law: 2026 Update, Justice Charles W. Johnson, Justice Debra L. Stephens, Justice Steven González

Seattle University Law Review

This Survey is intended to serve as a resource which Washington lawyers, judges, law enforcement officers, and others can turn to as an authoritative starting point for researching Washington search and seizure law. In order to be useful as a research tool, this Survey requires periodic updates to address new cases interpreting the Washington constitution and the U.S. Constitution and to reflect the current state of the law. As the U.S. Supreme Court has continued to examine Fourth Amendment search and seizure jurisprudence, its decisions and reflections on Washington law are discussed.

Most of the Survey cases involve the Washington …

(Mis)Judging Suspicion, Sherri Lee Keene

Georgetown Law Faculty Publications and Other Works

Twenty-five years ago, the Supreme Court decided Illinois v. Wardlow, a Fourth Amendment case that allowed the high-crime nature of a location to be considered in determinations of whether there was reasonable suspicion to support a police stop. In making these determinations, courts rarely acknowledge the role that race can play in decisions that factor in the nature of a location as context. Yet even when the race of a defendant is not mentioned, high-crime area designations can act as a proxy for race inviting racial bias into courts’ analyses. Reasonable suspicion analysis involves the interpretation of a suspect’s …

"Intolerable" Inquiries, Zachary R. Cormier

St. John's Law Review

(Excerpt)

A growing majority of courts have broadly accepted travel-plan questions (and their follow-up questions) as a qualifying category of traffic-mission inquiries under Rodriguez, leaving officers with a clear pathway from pretextual traffic stop—to extended discussion about vehicle occupant activities outside the traffic violation—to drug dog sniff—to vehicle search. A closer analysis of Rodriguez, however, precludes such passage through the heart of its traffic-mission rule. This Article will demonstrate that travel-plan questioning cannot qualify alongside the roadway safety checks identified by Rodriguez in its traffic-mission inquiry list because such checks provide direct information about another safety-related traffic violation …

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 …

The Automated Fourth Amendment, Maneka Sinha

Emory Law Journal

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 …

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 Black Fourth Amendment, Charisma Hunter

Washington and Lee Law Review Online

Policing Black bodies serves at the forefront of the American policing system. Black bodies are subject to everlasting surveillance through institutions and everyday occurrences. From relaxing in a Starbucks to exercising, Black bodies are deemed criminals, surveilled, profiled, and subjected to perpetual implicit bias when participating in mundane activities. Black people should have the same protections as white people and should possess the ability to engage in everyday, commonplace, and routine activities.

The Fourth Amendment was not drafted with the intention of protecting Black bodies. In fact, Black bodies were considered three-fifths of a person at the drafting of the …

“Bang!”: Shotspotter Gunshot Detection Technology, Predictive Policing, And Measuring Terry’S Reach, Harvey Gee

University of Michigan Journal of Law Reform

ShotSpotter technology is a rapid identification and response system used in ninety American cities that is designed to detect gunshots and dispatch police. ShotSpotter is one of many powerful surveillance tools used by local police departments to purportedly help fight crime, but they often do so at the expense of infringing upon privacy rights and civil liberties. This Article expands the conversation about ShotSpotter technology considerably by examining the adjacent Fourth Amendment issues emanating from its use. For example, law enforcement increasingly relies on ShotSpotter to create reasonable suspicion where it does not exist. In practice, the use of ShotSpotter …

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, …

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” …

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 …

Dudley Do Wrong: An Analysis Of A "Stop And Identify" Statute In Hiibel V. Sixth Judicial District Of Nevada, James G. Warner

Akron Law Review

Part II of this note traces the development of “stop and identify” statutes, including its origins in historical vagrancy and loitering statutes, courts’ treatment of such laws, and the progression of the specific Nevada statute at issue. Part III examines the appellate and Supreme Court decisions in the Hiibel case. Part IV analyzes the Court’s decision in Hiibel under the void for vagueness doctrine and the Fourth and Fifth Amendments, and highlights the recent enactment of a “stop and identify” statute in Arizona. Finally, Part V concludes that the Nevada “stop and identify” statute allows too great of an intrusion …

Big Data And Predictive Reasonable Suspicion, Andrew Ferguson

Scholarly Articles in Law Reviews & Journals

The Fourth Amendment requires “reasonable suspicion” to seize a suspect. As a general matter, the suspicion derives from information a police officer observes or knows. It is individualized to a particular person at a particular place. Most reasonable suspicion cases involve police confronting unknown suspects engaged in observable suspicious activities. Essentially, the reasonable suspicion doctrine is based on “small data” – discrete facts involving limited information and little knowledge about the suspect.But what if this small data is replaced by “big data”? What if police can “know” about the suspect through new networked information sources? Or, what if predictive analytics …

Nuance, Technology, And The Fourth Amendment: A Response To Predictive Policing And Reasonable Suspicion, Fabio Arcila Jr.

Scholarly Works

In an engaging critique, Professor Arcila finds that Professor Ferguson is correct in that predictive policing will likely be incorporated into Fourth Amendment law and that it will alter reasonable suspicion determinations. But Professor Arcila also argues that the potential incorporation of predictive policing reflects a larger deficiency in our Fourth Amendment jurisprudence and that it should not be adopted because it fails to adequately consider and respect a broader range of protected interests.

Probable Cause And Reasonable Suspicion: Totality Tests Or Rigid Rules?, Kit Kinports

Faculty Scholarship

This piece argues that the Supreme Court's April 2014 decision in Navarette v. Calfornia, like last Term's opinion in Florida v. Harris, deviates from longstanding Supreme Court precedent treating probable cause and reasonable suspicion as totality-of-the-circumstances tests. Instead, these two recent rulings essentially rely on rigid rules to define probable cause and reasonable suspicion. The article criticizes the Court for selectively endorsing bright-line tests that favor the prosecution, and argues that both decisions generate rules that oversimplify and therefore tend to be overinclusive.
