Textual (In)Difference In State Search-And-Seizure Provisions, Quinn Yeargain

Northwestern University Law Review

Over the past 250 years, state constitutional drafters have refined the scope of rights and liberties protected by their constitutions’ texts. Today, all state constitutions include a search-and-seizure provision—and though only a minority follow the layout, text, and context of the Fourth Amendment to the U.S. Constitution, most of them bear a striking resemblance to it. However, textual variations abound. Some of them may seem minor, like using the word “possessions” instead of “effects,” or mandating that warrants describe their intended targets “as nearly as may be” instead of requiring that they “particularly describ[e]” them. But others, like the addition …

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 …

"People" Not "Persons": Noncitizens And The Fourth Amendment, Juan Caballero

Loyola of Los Angeles Law Review

American history is littered with threats and attempts at mass deportation. The Trump administration’s announced policy of mass deportations is the most recent manifestation of such a policy and one that perhaps poses an unprecedented threat to the rights and liberties of noncitizen communities. The administration’s aggressive rhetoric, militarized border policy, and embrace of new technology together portend a new era of surveillance and control over noncitizen communities. This threatens to supercharge previous and ongoing surveillance efforts within the immigration enforcement paradigm, such as the Department of Homeland Security's Alternatives to Detention (“ATD”) program. These programs place participants under a …

Cross-Enforcing The Plain Smell Doctrine, Alexa Perez

Washington Law Review

In a state that has legalized marijuana, does a state officer have probable cause to conduct a warrantless search of a vehicle based on the smell of marijuana alone, because marijuana is still prohibited under federal law? This Article is the first to consider that unsettled question. Over the last ten years, almost every state has altered the legality of marijuana in some way, either through decriminalization or legalization. Yet the possession, use, and cultivation of marijuana continue to be illegal at the federal level. Prior to these reforms, state courts generally upheld warrantless searches of vehicles based on nothing …

Reasonable, Legal, Voluntary? Grants Pass Decision Sparks Need For A Revised Fourth Amendment Search Analysis In The Context Of Homelessness, Hali R. Woods

Catholic University Law Review

On June 28, 2024 the Supreme Court decided City of Grants Pass, Oregon v. Johnson.  The case addressed whether the enforcement of city ordinances regulating camping on public property against individuals including respondents, unhoused individuals residing in the city of Grants Pass, constituted cruel and unusual punishment under the Eighth Amendment.  The Court upheld enforcement of the ordinances and since then approximately 150 cities across the United States have passed similar ordinances or strengthened existing similar laws.  This comment evaluates how Grants Pass is an Eighth Amendment case with Fourth Amendment consequences which sparks a need for a revised …

Time As A Constitutional Constraint: Resolving The Circuit Split On Prolonged Fourth Amendment, Ian Seabrooks

Washington Law Review Online

The Fourth Amendment of the U.S. Constitution states, “[t]he right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated. . . .” Some circuits, like the Ninth and D.C. Circuits, have interpreted the Fourth Amendment’s reasonableness standard to apply beyond just the initial seizure of property but also to include the continued retention of the seized property. Other circuits, such as the First, Second, Sixth, Seventh, and Eleventh Circuits, have read the reasonableness standard more narrowly and interpreted this requirement to pertain only to the original seizure. …

Justifying The Fourth Amendment, Daniel Epps

Scholarship@WashULaw

Why does the Fourth Amendment belong in the Constitution? This question is not whether society should impose some legal restraints on government searches and seizures. Rather, why should such protections reside in our national charter, superior to other forms of law and insulated from change via ordinary majoritarian political processes? Despite major disputes about the Fourth Amendment’s content, Fourth Amendment theorists rarely ask this question. Almost all agree that the Fourth Amendment’s constitutional protections are critically important—even if no one can agree exactly what those protections are.

Police Officer Use Of Force And Officer-Created Jeopardy After Barnes V. Felix: The Supreme Court's Important (Albeit Incomplete) Step In The Right Direction, Cynthia Lee

ConLawNOW

This essay analyzes the Supreme Court’s 2025 unanimous decision in Barnes v. Felix rejecting the moment of threat doctrine that limited courts assessing the reasonableness of a law enforcement officer’s use of force. Under this narrow time-framing approach, courts were limited to considering only those facts and circumstances known to the officer at the moment of the threat, and acts occurring before the officer seized the individual that may have contributed to the dangerous situation could not be considered. Rejecting this narrow approach, the Court reaffirmed its longstanding rule that in assessing the reasonableness of an officer’s use of force …

The Equal Protection-Fourth Amendment Shell Game: An Essay On The Limited Reach Of The 2023 Affirmative Action Cases, The Fourth Amendment, And Race Beyond Skin Color, David B. Owens

Articles

In striking down race-conscious admissions at Harvard and the University of North Carolina, the Supreme Court used lofty rhetoric about the importance of ending race discrimination, even calling the command of Equal Protection “universal.” In two ways, this Essay explores the legal and practical limits of the affirmative action cases and illustrates how the Court’s claimed concern about race discrimination rings hollow. First, this Essay discusses state actors permitted to use race in their decision-making: the police. Unlike elite universities whose policies are subject to exacting scrutiny, the Supreme Court permits police to use race when deciding whom to seize …

What’S In A Name? How The Eleventh Circuit Ignored The Fourth Amendment To Hold That A Warrant For One Person Authorizes The Detention Of Others, Jared Mcclain, Dylan Moore

University of Miami Law Review

Odds are, your name isn’t all that unique. Most people share the same first and last name with hundreds, if not thousands, of other Americans. The frequency with which people share a name raises an important question of civil rights: What happens when officers arrest and detain an innocent person based on an arrest warrant that was issued for someone else with the same name?

In the Eleventh Circuit, the answer is almost always “nothing.” So long as a mistaken detention lasts three days or fewer, officers are free from accountability for apprehending the innocent—even if those officers have good …

Caution: Potholes In E-Scooter Data Collection, Dakota Rakestraw

Seattle University Law Review

Lime scooters keep ending up in major waterways in Washington state metro areas, a testament to the ubiquity of e-scooters in the metropolitan landscape. How they get there is unclear. Why they get there is even murkier. Perhaps the answer lies in the implications of modern geolocation data collection through e-scooters and gaps in current data collection regulation curbing individual liberties.

Since September 2020, electric scooters have run Seattle’s streets and have dramatically overtaken ridesharing bike trips. For example, from September 2020 to September 2021, there were about 1.4 million scooter and bike trips with September 2021 seeing 300,000 scooter …

Privacy In The Age Of Platforms: How Digital Advancements Are Outrunning Our Constitution, Haleigh Fagundes

Capstone Projects and Master's Theses

This project analyzes the procedural history of Fourth Amendment doctrine in the Supreme Court. This timeline begins with the 1928 case of Olmstead v. United States and proceeds with recent cases that resolve more modern concerns such as location tracking via cell-cite information, as seen in Carpenter v. United States (2018). Prevalent cases are analyzed through both majority and dissenting opinions to demonstrate the entire Courts’ attitude towards the interpretation. Though more recently the Court has moved towards expanding the expectation of privacy that one can assume from the Fourth Amendment, digital privacy has yet to be incorporated. The research …

Trespass To Chattel And The Fourth Amendment, Will Baskin

Texas A&M Journal of Property Law

Like an adolescent maturing into adulthood, Fourth Amendment search doctrine has gone through phases. Scholars may debate the underlying principles that have governed each phase, but they agree that two Supreme Court decisions dominate the doctrine as it stands today: Katz v. United States and United States v. Jones. The younger of these two rivals, Jones, has caused its share of consternation. Courts have struggled to consistently apply its trespass-based test, despite the test’s seemingly simple formulation. This Note considers the Jones test in the context of personal property, or chattel, making two arguments: first, careful adherence to common-law principles …

Peeping Town: Drone Surveillance And The Exclusionary Rule In Long Lake Township V. Maxon, Stuart Massa

Northwestern University Law Review

For years, legal commentators have pondered the effect of the Fourth Amendment on drones, but purely as an academic exercise. No court had ever considered drone surveillance under the Fourth Amendment––until now. In Long Lake Township v. Maxon, a northern Michigan township flew a drone over a local resident’s home to gather photographic evidence of an alleged zoning violation. Relying on that evidence, the township sued to enforce its zoning ordinance. The resident moved to suppress the evidence, arguing that the drone’s warrantless surveillance violated the Fourth Amendment. The case made it all the way up to the Michigan …

Loopholes Of Liberty: The Supreme Court’S Evisceration Of The Fourth Amendment, David J. Looney

Touro Law Review

The Fourth Amendment’s protections against unwarranted government intrusion are currently undermined by the Supreme Court’s third party and open fields doctrines, which permit warrantless access to shared data and private land beyond a home’s curtilage, clashing with the Amendment’s aim to safeguard privacy and property in an era of advanced surveillance. These doctrines enable arbitrary governmental overreach, necessitating urgent review to restore constitutional protections. Rooted in Enlightenment principles, the Fourth Amendment historically protected “papers” and “effects” from physical trespass, as seen in Boyd v. United States. Katz v. United States introduced a “reasonable expectation of privacy” test, but its subjective …

Facial Recognition Technology And The First Amendment, Joseph A. Tomain

Articles by Maurer Faculty

The growing ubiquity of facial recognition technology (FRT) is a problem. While much has been written on harmful government use of FRT, little has been written regarding harmful private actor use. This Article helps fill a gap in the literature by providing a detailed analysis of the First Amendment interests at stake when private actors use FRT. Specifically, this Article analyzes whether laws that limit the use of publicly available photographs to create faceprints for inclusion in FRT databases violate the First Amendment rights of private actors.

In May 2025, a multidistrict litigation against Clearview AI, an FRT company, offered …

Internet Search Engines’ Privacy Violations And The Lack Of Federal Regulation To Protect Consumers Rights, Elsa M. G. Rodriguez Ogando

Dickinson Law Review (2017-Present)

The United States’ current legal framework regarding internet search engines is disadvantageous to consumers. Federal privacy laws (although not encompassing search engines) grant businesses a strong legal basis in privacy claims and alibies for arbitrary behavior; these laws favor businesses over consumers. Moreover, state privacy laws empower nonspecific agencies to oversee privacy matters and enforce consumers’ rights. Thus, the U.S. privacy legal framework is in need of a new federal law that establishes consumers’ rights, as well as a federal agency dedicated solely to privacy matters. This Article proposes a federal law recommendation based on the standards of the California …

Free Movement Rights And The American City, Ryan Stoa

FIU Law Review

American cities are facing an inflection point. Widespread dissatisfaction with urban planning outcomes is making land use and transportation policies (such as congestion pricing) a mainstream topic of debate. Suburban sprawl and housing shortages are moving urban populations into the periphery, commuting times (and associated mental health problems) are increasing, and pedestrian and cyclist deaths caused by vehicles are at all-time highs. American cities that were largely planned and built in the twentieth century based on assumptions that we now know are flawed are not meeting the needs of their residents, and urban planners are making changes to reshape urban …

Family Regulation's Consent Problem, Anna Arons

Faculty Publications

The home is the most protected space in constitutional law. But family regulation investigators conduct millions of home searches a year. Under pressure, parents nearly always consent to these state agents’ entry into the most private areas of their lives.

This Article identifies the coercive forces—not least the threat of family separation—that drive parents to consent to home searches. Drawing on primary sources and case law examining consent in criminal cases, it shows that common family regulation investigation tactics render consent involuntary and the ensuing searches unconstitutional. And yet, it argues, the Constitution is not enough. Though constitutional litigation could …

Video Analytics And Fourth Amendment Vision, Andrew Guthrie Ferguson

Scholarly Articles in Law Reviews & Journals

What does the Fourth Amendment have to say about video analytics running on citywide camera systems? Video analytics (also known as computer vision) involves hardware and software in cameras that turns video surveillance streams into useful data, identifying, categorizing, matching, and alerting police about objects, people, and incidents. Video analytics can identify objects (e.g., hat, backpack, person, car) and track that person or thing back in time and through the streets using video surveillance footage. For police officers conducting virtual patrols or retrospective investigations, video analytics lets police scan thousands of linked cameras for suspicious behavior or a particular suspect, …

The Reality Of The Good Faith Exception, Michael Gentithes, Matthew Tokson

Akron Law Faculty Publications

This Article has reexamined the law and theory of the good faith exception. It fnds that the exception, originally confned to narrow circumstances, is turning into a protection for nearly any investigatory activity with an arguable connection to an existing precedent or statute. Our study is the frst to empirically demonstrate the exception’s substantial infuence on modern Fourth Amendment law. Courts rely on the exception with remarkable frequency, and a large proportion of courts invoking the exception avoid any substantive constitutional ruling, stunting the development of Fourth Amendment doctrine. Further, our close theoretical examination of the good faith exception reveals …

Back To The Future: Revisiting State Constitutions To Protect Against New Technological Intrusions, Matthew Radford

Washington and Lee Law Review

The Fourth Amendment is crucial for protecting Americans from government intrusion. However, new technologies such as pole cameras, reverse keyword searches, and geofence searches provide new ways for governments to gather information about individuals. As these new technologies develop, the Fourth Amendment has struggled to advance alongside this new technology.

Thankfully, the Fourth Amendment is not the only protection Americans have from government intrusion. Every single state has its own state constitution and analog to the Federal Fourth Amendment. In fact, some states had their own analog amendments even before the adoption of the Federal Fourth Amendment. While oftentimes the …

Police Shootings After Torres V. Madrid: Suspects Eluding Capture Are Seized Under Fourth Amendment, Travis R. Thickstun

The Scholar: St. Mary's Law Review on Race and Social Justice

In Torres v. Madrid, the Supreme Court held that the application of physical force to the body of a person with intent to restrain is a seizure even if the person does not submit and is not subdued. Because this new rule brings even the slightest touches within the Fourth Amendment’s protections against unreasonable searches and seizures, it allows more claims against police officers for violations of the Fourth Amendment’s prohibition on unreasonable searches and seizures.

Until the Torres decision though, only when someone shot by police was actually taken into custody could that person sue the police officers …

Going Cashless: Privacy Implications For Gun Control In A Digital Economy, Liza Goldenberg

The Journal of Business, Entrepreneurship & the Law

This paper will examine how, given the United States’ shift toward a cashless economy, the country’s top credit-card companies’ potential decision to implement a new merchant code for firearm-related transactions as a method of gun control will backfire, jeopardizing consumer privacy and leading to unregulated transactions through cryptocurrencies. Since the majority of gun violence stems from firearm transactions not involving credit cards, credit-card companies should abandon the new merchant code that dissuades Americans from exercising their fundamental rights. The American economy should focus on slowing the shift toward a digital economy so that federal and state governments can implement legislation …

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 …
