Fourth Amendment Notice In The Cloud, Neil M. Richards, Jesse Lieberfeld

Scholarship@WashULaw

The widespread storage of documents through the range of Internet technologies known as “the cloud” offers tremendous convenience but also creates significant risks of exposure to third parties. In particular, law enforcement investigators seeking access to potentially relevant evidence have aggressively and extensively used the Electronic Communications Act of 1986 (“ECPA”) to execute digital searches. But a relatively obscure provision of ECPA, § 2703, allows law enforcement to search a person’s Fourth Amendment “papers” without them ever learning that a warrant has allowed the exposure of their private, sensitive, and possibly incriminating documents. What is more, federal and state law …

The Fourth Amendment And General Law, Daniel Epps, Danielle D'Onfro

Scholarship@WashULaw

For decades, Fourth Amendment protections have turned on “reasonable expectations of privacy.” But a new era may be dawning. There is growing interest among judges and scholars in turning away from privacy toward property or positive law as the touchstone for Fourth Amendment protections. Yet many questions remain about how that approach should work, such as where judges should look for positive law and precisely what role positive law should play in Fourth Amendment analysis.

This Article answers those questions, and in so doing lays forth a new, comprehensive theory of the Fourth Amendment. We argue that courts should interpret …

The Carpenter Test As A Transformation Of Fourth Amendment Law, Matthew Tokson

Utah Law Faculty Scholarship

For over fifty years, the Fourth Amendment’s scope has been largely dictated by the Katz test, which applies the Amendment’s protections only when the government has violated a person’s “reasonable expectation of privacy.” This vague standard is one of the most criticized doctrines in all of American law, and its lack of coherence has made Fourth Amendment search law notoriously confusing. Things have become even more complex following the Supreme Court’s landmark decision in Carpenter v. United States, which has spawned its own alternative test for determining the Fourth Amendment’s scope. The emerging Carpenter test looks to the revealing nature …

Warranted Exclusion: A Case For A Fourth Amendment Built On The Right To Exclude, Mailyn Fidler

SMU Law Review

Searches intrude; fundamentally, they infringe on a right to exclude. So that right should form the basis of Fourth Amendment protections. Current Fourth Amendment doctrine—the reasonable expectation of privacy test—struggles with conceptual clarity and predictability. The Supreme Court’s recent decision to overturn Roe v. Wade casts further doubt on the reception of other privacy-based approaches with this Court. But the replacement approach that several Justices on the Court favor, what I call the “maximalist” property approach, risks troublingly narrow results. This Article provides a new alternative: Fourth Amendment protection should be anchored in a flexible concept derived from property law—what …

The Empty Promise Of The Fourth Amendment In The Family Regulation System, Anna Arons

Faculty Publications

Each year, state agents search the homes of hundreds of thousands of families across the United States under the auspices of the family regulation system. Through these searches—required elements of investigations into allegations of child maltreatment in virtually every jurisdiction—state agents invade the home, the most protected space in Fourth Amendment jurisprudence. Accordingly, federal courts agree that the Fourth Amendment’s warrant requirement applies to family regulation home searches. But almost universally, the abstract recognition of Fourth Amendment protections runs up against a concrete expectation on the ground that state actors should have easy and expansive access to families’ homes. Legislatures …

Thompson V. Clark And The “Reasonable” Policing Of Marginalized Families, Anna Arons

Faculty Publications

This Article uses the experience of Larry Thompson, the plaintiff in Thompson v. Clark, 142 S. Ct. 1332 (2022), to examine the absence of privacy for poor families, particularly poor Black, Latinx, and Native families, in the United States. Mr. Thompson may end up remembered in legal history as a victor, as the Supreme Court lowered the barriers to bringing malicious prosecution claims and reinstated Mr. Thompson’s own previously dismissed malicious prosecution claim. Yet before securing this victory, Mr. Thompson lost a slew of other Fourth Amendment claims against the police. Mr. Thompson’s claims arose from state agents’ warrantless …

Exigencies, Not Exceptions: How To Return Warrant Exceptions To Their Roots, Michael Gentithes

Akron Law Faculty Publications

When a police officer interacts with an individual, the encounter is subject to myriad exceptions to the Fourth Amendment’s warrant requirement that lack a coherent justifying theory. For instance, officers can warrantlessly search if an automobile was involved in the interaction, an arrest occurred, or a protective sweep was necessary to prevent a third- party ambush. Officers and indi viduals struggle to understand the breadth and complexity of these exceptions. The resulting confusion breeds widespread distrust and raises the tension in millions of interactions across the country. There is an easier way. The Supreme Court has recently reaffirmed its support …

Crimes Of Suspicion, Lauryn P. Gouldin

Emory Law Journal

Requiring that officers have suspicion of specific crimes before they seize people during stops or arrests is a fundamental rule-of-law limitation on government power. Until very recently, the Supreme Court studiously avoided saying whether reasonable suspicion for street and traffic stops must be crime specific, and lower courts are sharply divided as a result. Statements made in Kansas v. Glover that the Fourth Amendment requires reasonable suspicion of a “particular crime” or of “specific criminal activity” may reflect an effort to rehabilitate this foundational principle, but crime specificity was not the Court’s focus in Glover. Meanwhile, Fourth Amendment scholars, even …

Evolving Privacy Protections For Emerging Machine Learning Data Under Carpenter V. United States, Emily Nicolella

FIU Law Review

The Fourth Amendment’s third-party doctrine eliminates an individual’s reasonable expectation of privacy in information they willingly turn over to third parties. Government scrutiny of this information is not considered a search under the Fourth Amendment and is therefore not given constitutional protections. In the 2018 case Carpenter v. United States, the Supreme Court created an exception to the third-party doctrine. In Carpenter, a case involving the warrantless use of cell site location information (CSLI) in a criminal investigation, the Court held that individuals do have a reasonable expectation of privacy regarding CSLI. According to Chief Justice Roberts, despite the necessary …

On Warrants & Waiting: Electronic Warrants & The Fourth Amendment, Tracy Hresko Pearl

Faculty Articles

Police use of electronic warrant (“e-warrant”) technology has increased significantly in recent years. E-warrant technology allows law enforcement to submit, and magistrate judges to review and approve, warrant applications on computers, smartphones, and tablets, often without any direct communication. Police officers report that they favor e-warrants over their traditional counterparts because they save officers a significant amount of time in applying for warrants by eliminating the need to appear in-person before a magistrate. Legal scholars have almost uniformly praised e-warrant technology, as well, arguing that use of these systems will increase the number of warrants issued throughout the United States …

Is There A Fundamental Right To Privacy When An Educational Institution Requires A Student To Disclose Proof Of His Or Her Vaccination Status?, Mary D. Fatscher

Touro Law Review

In 2020, the coronavirus disease (“COVID-19”) dominated the world. Although the public has progressively become more informed about the disease and how to safeguard itself, challenges persist as there is still much unknown. Aside from wearing masks, social distancing, and despite its undetermined consequences, the COVID-19 vaccination has emerged as a primary solution to substantially reducing the incidence and severity of the virus in our country. Many COVID-19 vaccine mandates were initiated once three pharmaceutical and biotechnology companies including Pfizer-BioNTech, Moderna, and Johnson & Johnson received Emergency Use Authorization from the Food and Drug Administration (“FDA”).

Scanning Iphones To Save Children: Apple’S On-Device Hashing Algorithm Should Survive A Fourth Amendment Challenge, Timothy Gernand

Dickinson Law Review (2017-Present)

When Apple announced it would combat the growth of child sexual abuse material (CSAM) on its platform by scanning all its users’ devices without their consent, many of its loyal customers felt betrayed. With tech companies such as Google and Facebook arranging their business models around selling their customers’ personal information, Apple customers saw the company’s focus on privacy as a refreshing alternative. However, as Apple itself privately acknowledged, this emphasis on privacy had led to it becoming a haven for CSAM. Despite the reputational damage it would incur with its customers, Apple resolved to confront CSAM on its platform …

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 …

Digitizing The Fourth Amendment: Privacy In The Age Of Big Data Policing, Charles E. Volkwein

Privacy Certificate Student Publications

Today’s availability of massive data sets, inexpensive data storage, and sophisticated analytical software has transformed the capabilities of law enforcement and created new forms of “Big Data Policing.” While Big Data Policing may improve the administration of public safety, these methods endanger constitutional protections against warrantless searches and seizures. This Article explores the Fourth Amendment consequences of Big Data Policing in three parts. First, it provides an overview of Fourth Amendment jurisprudence and its evolution in light of new policing technologies. Next, the Article reviews the concept of “Big Data” and examines three forms of Big Data Policing: Predictive Policing …

High Time For Change: The Legalization Of Marijuana And Its Impact On Warrantless Roadside Motor Vehicle Searches, Molly E. O'Connell

Washington and Lee Law Review Online

The proliferation of marijuana legalization has changed the relationship between driving and marijuana use. While impaired driving remains illegal, marijuana use that does not result in impairment is not a bar to operating a motor vehicle. Scientists have yet to find a reliable way for law enforcement officers to make this distinction. In the marijuana impairment context, there is not a scientifically proven equivalent to the Blood Alcohol Content standard nor are there reliable roadside assessments. This scientific and technological void has problematic consequences for marijuana users that get behind the wheel and find themselves suspected of impaired driving. Without …

Where There Is A Right, There Is A Remedy—Or Is There?, Grace Panicola

SLU Law Journal Online

Courts have repeatedly declined to allow causes of actions under the Constitution when Plaintiffs’ constitutional rights are violated by government officials. In this article, Grace Panicola discusses a pocket of governmental immunity that creates serious implications for Plaintiffs as they ultimately face inadequate remedies.

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. …

It Just Makes Sense: An Argument For A Uniform Objective Standard For Incarcerated Individuals Bringing Claims Under 42 U.S.C. § 1983, Pearce Thomson Embrey

Washington and Lee Journal of Civil Rights and Social Justice

In July 2020, the New York Times published an article on a Department of Justice report detailing the systematic abuse of incarcerated individuals by prison guards within the State of Alabama’s Department of Corrections. This report evidences the challenges faced by incarcerated individuals seeking to vindicate their Eighth Amendment rights. In a legal sense, those individuals who turn to the court system for relief face an almost insurmountable burden of proof. This Note begins by surveying the history of excessive force claims under the Fourth, Eighth, and Fourteenth Amendments, as well as deliberate indifference claims under the Eighth and Fourteenth …

Legal Implications Of A Ubiquitous Metaverse And A Web3 Future, Jon M. Garon

Marquette Law Review

The metaverse is understood to be an immersive virtual world serving as the locus for all forms of work, education, and entertainment experiences. Depicted in books, movies, and games, the metaverse has the potential not just to supplement real-world experiences but to substantially supplant them. This Article explores the rapid emergence and evolution of the Web3 technologies at the heart of the metaverse movement. Web3 itself is a paradigmatic shift in internet commerce.

Catchall Policing And The Fourth Amendment, Nirej Sekhon

Duke Law Journal Online

American police do a bit of everything. They direct traffic, resolve private disputes, help the sick and injured, and do animal control. Far less frequently than one might think, they make arrests. Americans reflexively call the police for troubles, big and small. The “catchall tradition” is shorthand for this melding of non-adversarial, public assistance with adversarial, crime-control functions. The catchall tradition means that civilians are exposed to the police’s coercive power as a condition of receiving police help. This Article contends that the catchall tradition is antithetical to constitutional police regulation. The Supreme Court has distinguished adversarial from non-adversarial state …

“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 …

Deprogramming Bias: Expanding The Exclusionary Rule To Pretextual Traffic Stop Using Data From Autonomous Vehicle And Drive-Assistance Technology, Joe Hillman

University of Michigan Journal of Law Reform

As autonomous vehicles become more commonplace and roads become safer, this new technology provides an opportunity for courts to reconsider the constitutional rationale of modern search and seizure law. The Supreme Court should allow drivers to use evidence of police officer conduct relative to their vehicle’s technological capabilities to argue that a traffic stop was pretextual, meaning they were stopped for reasons other than their supposed violation. Additionally, the Court should expand the exclusionary rule to forbid the use of evidence extracted after a pretextual stop. The Court should retain some exceptions to the expanded exclusionary rule, such as when …

An Argument Against Unbounded Arrest Power: The Expressive Fourth Amendment And Protesting While Black, Karen J. Pita Loor

Michigan Law Review

Protesting is supposed to be revered in our democracy, considered “as American as apple pie” in our nation’s mythology. But the actual experiences of the 2020 racial justice protesters showed that this supposed reverence for political dissent and protest is more akin to American folklore than reality on the streets. The images from those streets depicted police officers clad in riot gear and armed with shields, batons, and “less than” lethal weapons aggressively arresting protesters, often en masse. In the first week of the George Floyd protests, police arrested roughly 10,000 people, and approximately 78 percent of those arrests were …

Dna Dystopia: How The National Security Apparatus Could Map The Entire Genome Of America Without Violating The Fourth Amendment Or The Constitutional Right To Privacy, Elias Rios Iii

Brooklyn Law Review

Over the past decade, scientific advances have allowed genetic testing to become accessible to consumers. Direct-to-consumer (DTC) DNA testing companies can analyze your DNA sample so you can learn about your family’s origins or whether you are genetically predisposed to a specific disease or disorder. Consumers can then send these analyzed files to third-party databases that aggregate genetic data for specific purposes, like helping law enforcement solve cold cases. Recently, the Department of Defense alerted servicemembers that DTC DNA tests were a national security threat. Simply put, when the national security apparatus finds a threat, it proactively seeks to neutralize …

Warrant Nullification, L. Joe Dunman

West Virginia Law Review

Police officers execute thousands of search warrants in the United States every year, often looking for drugs in people's homes. Many search warrants are executed by militarized "dynamic entry" teams who violently conduct raids late at night with little or no warning, guns drawn. These raids have killed and injured hundreds of people nationwide-not just suspects but also officers and bystanders. Protests erupt in response, the community divides, and trust in institutions crumbles.

Legislative and executive policy can reduce the violence of search warrant executions, but could there also be a judicial option? This Article explores one such option: nullification. …

Are Constitutional Rights Enough? An Empirical Assessment Of Racial Bias In Police Stops, Rohit Asirvatham, Michael D. Frakes

Northwestern University Law Review

This Article empirically tests the conventional wisdom that a permissive constitutional standard bearing on pretextual traffic stops—such as the one announced by the Supreme Court in Whren v. United States—contributes to racial disparities in traffic stops. To gain empirical traction on this question, we look to state constitutional law. In particular, we consider a natural experiment afforded by changes in the State of Washington’s rules regarding traffic stops. Following Whren, the Washington Supreme Court first took a more restrictive stance than the U.S. Supreme Court, prohibiting pretextual stops by police officers, but later reversed course and instituted a …
