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 …

Wrong Search At The Wrong Time: Keyword Search Warrants And The Fourth Amendment, Nicole Chan

Articles

This Note will advocate for the view that when presented with the issue, state and federal courts should establish that keyword search warrants are unconstitutional because they violate the Fourth Amendment. Keyword search warrants cannot meet the Fourth Amendment’s requirements of probable cause and particularity because the subjects of the search cannot be identified until after the search is completed. These warrants are unnecessary and have the potential of implicating millions of internet users who have no connection to a crime. This Note will contend that individuals have a reasonable expectation of privacy in their search history data, and that …

Administrative Regulation Of Programmatic Policing: Why "Leaders Of A Beautiful Struggle" Is Both Right And Wrong, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In Leaders of a Beautiful Struggle v. Baltimore Police Department, the Fourth Circuit Court of Appeals held that Aerial Investigation Research (AIR), Baltimore's aerial surveillance program, violated the Fourth Amendment because it was not authorized by a warrant. AIR was constitutionaly problematic, but not for the reason given by the Fourth Circuit. AIR, like many other technologically-enhanced policing programs that rely on closed-circuit television (CCTV), automated license plate readers and the like, involves the collection and retention of information about huge numbers ofpeople. Because individualized suspicion does not exist with respect to any of these people's information, an individual-specific warrant …

Privacy And Property: Constitutional Concerns Of Dna Dragnet Testing, E. Wyatt Jones

Honors Projects

DNA dragnets have attracted both public and scholarly criticisms that have yet to be resolved by the Courts. This review will introduce a modern understanding of DNA analysis, a complete introduction to past and present Fourth and Fourteenth Amendment jurisprudence, and existing suggestions concerning similar issues in legal scholarship. Considering these contexts, this review concludes that a focus on privacy and property at once, with a particular sensitivity to the inseverable relationship between the two interests, is Constitutionally consistent with precedent and the most workable means of answering the question at hand.

The Tesla Meets The Fourth Amendment, Adam M. Gershowitz

Faculty Publications

Can police search a smart car’s computer without a warrant? Although the Supreme Court banned warrantless searches of cell phones incident to arrest in Riley v. California, the Court left the door open for warrantless searches under other exceptions to the warrant requirement. This is the first article to argue that the Fourth Amendment’s automobile exception currently permits the police to warrantlessly dig into a vehicle’s computer system and extract vast amounts of cell phone data. Just as the police can rip open seats or slash tires to search for drugs under the automobile exception, the police can warrantlessly …

Privacy And National Politics: Fingerprint And Dna Litigation In Japan And The United States Compared, Dongsheng Zang

Articles

Drawing cases from two related areas of law-fingerprint and DNA (deoxyribonucleic acid) data-this Article proposes a modified framework, built on the Balkin-Levinson emphasis on national politics: First, national politics understood as partisan rivalry cannot account for what I call doctrinal lock-in in this Article, where I will demonstrate that in different stages of American politics-the Lochner era, the New Deal era, and Civil Rights era-courts across the nation ruled predominantly in favor of public data collectors-state and federal law enforcement in fingerprint cases. From the 1990s, when DNA data became hot targets of law enforcement, the United States Supreme Court …

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 …

The New Bailments, Danielle D'Onfro

Scholarship@WashULaw

The rise of cloud computing has dramatically changed how consumers and firms store their belongings. Property that owners once managed directly now exists primarily on infrastructure maintained by intermediaries. Consumers entrust their photos to Apple instead of scrapbooks; businesses put their documents on Amazon’s servers instead of in file cabinets; seemingly everything runs in the cloud. Were these belongings tangible, the relationship between owner and intermediary would be governed by the common-law doctrine of bailment. Bailments are mandatory relationships formed when one party entrusts their property to another. Within this relationship, the bailees owe the bailors a duty of care …

Fourth Amendment Privacy In Public: A Fundamental Theory With Application To Location Tracking, Jordan Wallace-Wolf

Faculty Scholarship

When we walk out our front door, we are in public and other people may look at us. But intuitively, we don’t open ourselves up to unlimited scrutiny just by going outside. We retain some privacy, even in public. What is the source of this residual public-privacy, and how should the law recognize it without degrading the open character of public space?

The answer given by commentators, and most recently by the Supreme Court in Carpenter v. U.S., comes in the form of two related claims. The first is the chilling theory of the Fourth Amendment. According to this idea, …

Escaping Circularity: The Fourth Amendment And Property Law, João Marinotti

Articles by Maurer Faculty

The Supreme Court’s “reasonable expectation of privacy” test under the Fourth Amendment has often been criticized as circular, and hence subjective and unpredictable. The Court is presumed to base its decisions on society’s expectations of privacy, while society’s expectations of privacy are themselves presumed to be based on the Court’s judgements. As a solution to this problem, property law has been repeatedly propounded as an allegedly independent, autonomous area of law from which the Supreme Court can glean reasonable expectations of privacy without falling back into tautological reasoning.

Such an approach presupposes that property law is not itself circular. If …

Telephone Pole Cameras Under Fourth Amendment Law, Matthew Tokson

Utah Law Faculty Scholarship

In a series of recent cases, police officers have mounted sophisticated surveillance cameras on telephone poles and pointed them at the homes of people suspected of a crime. These cameras often operate for months or even years without judicial oversight, collecting vast quantities of video footage on suspects and their activities near the home. Pole camera surveillance raises important Fourth Amendment questions that have divided courts and puzzled scholars.

These questions are complicated because Fourth Amendment law is complicated. This is especially the case today as Fourth Amendment law is in a transitional phase, caught between older and newer paradigms …

Smart Meters As A Catalyst For Privacy Law, Matthew Tokson

Utah Law Faculty Scholarship

Smart utility meters raise several puzzling legal questions—and answering them can help point the way toward the future of Fourth Amendment and civil privacy law. This forum essay addresses two such issues: use restrictions on collected data, and voluntary data disclosure.

First, more than any other current technology, smart meters compel the development of use restrictions on collected data. The benefits of smart meters are potentially enormous, such that categorically prohibiting public utilities from collecting smart meter data is likely beyond the pale. Yet allowing law enforcement agents to obtain detailed or intimate data about the home without a warrant …

A World Of Difference? Law Enforcement, Genetic Data, And The Fourth Amendment, Christopher Slobogin, J. W. Hazel

Vanderbilt Law School Faculty Publications

Law enforcement agencies are increasingly turning to genetic databases as a way of solving crime, either through requesting the DNA profile of an identified suspect from a database or, more commonly, by matching crime scene DNA with DNA profiles in a database in an attempt to identify a suspect or a family member of a suspect. Neither of these efforts implicates the Fourth Amendment, because the Supreme Court has held that a Fourth Amendment "search" does not occur unless police infringe "expectations of privacy society is prepared to recognize as reasonable" and has construed that phrase narrowly, without reference to …

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 …

Cops And Cars: How The Automobile Drove Fourth Amendment Law, Tracey Maclin

Faculty Scholarship

This is an essay on Professor Sarah A. Seo’s new book, Policing the Open Road: How Cars Transformed American Freedom (Harvard Univ. Press 2019). I focus on Professor Seo’s analysis of Carroll v. United States, 267 U.S. 132 (1925) and Brinegar v. United States, 338 U.S. 160 (1949). Carroll is important not only because it was the Court’s first car case. Understanding Carroll (and Brinegar, which solidified and expanded Carroll’s holding) is essential because, nearly one hundred years later, its logic continues to direct how the modern Court resolves Fourth Amendment claims of motorists. Put simply, a majority of today’s …

The Exclusionary Rule In The Age Of Blue Data, Andrew Ferguson

Articles in Law Reviews & Other Academic Journals

In Herring v. United States, Chief Justice John Roberts reframed the Supreme Court’s understanding of the exclusionary rule: “As laid out in our cases, the exclusionary rule serves to deter deliberate, reckless, or grossly negligent conduct, or in some circumstances recurring or systemic negligence.” The open question remains: how can defendants demonstrate sufficient recurring or systemic negligence to warrant exclusion? The Supreme Court has never answered the question, although the absence of systemic or recurring problems has figured prominently in two recent exclusionary rule decisions. Without the ability to document recurring failures, or patterns of police misconduct, courts can dismiss …

Byrd V United States: Unauthorized Drivers Of Rental Cars Have Fourth Amendment Rights? Not As Evident As It Seems, Tracey Maclin

Faculty Scholarship

No discerning student of the Supreme Court would contend that Justice Anthony Kennedy broadly interpreted the Fourth Amendment during his thirty years on the Court. His majority opinions in Maryland v. King, Drayton v. United States and his willingness to join the three key sections of Justice Scalia’s opinion in Hudson v. Maryland, which held that suppression is never a remedy for knock-and-announce violations, are just a few examples of Justice Kennedy’s narrow view of the Fourth Amendment.

In light of his previous votes in search and seizure cases, surprisingly Justice Kennedy, in what would be his final Fourth Amendment …

The Value Of Deviance: Understanding Contextual Privacy, Timothy Casey

Faculty Scholarship

Recent decisions by the Supreme Court in Carpenter v. United States and the Illinois Supreme Court in Rosenbach v. Six Flags Entertainment Corporation signal a shift in the traditional understanding of what exactly is protected by a privacy interest. Carpenter distinguished between a police officer’s observation of a suspect’s location and a perpetual catalogue of a person’s movements obtained through cell site location information (CSLI). The pervasive and vast quantity of information from CSLI exposed a protected privacy interest. In Rosenbach, the Illinois Supreme Court found the unique and personal quality of biometric information meant that consent and disclosure requirements …

Functional Equivalence And Residual Rights Post-Carpenter: Framing A Test Consistent With Precedent And Original Meaning, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

The Carpenter Court held that warrantless access to seven or more days of cell site location information (CSLI) constitutes a violation of the reasonable expectation of privacy that individuals have in the whole of their physical movements. But the grounds on which the Court drew a line characterize all sorts of digital records—including those at issue in Miller and Smith, belying the majority’s claim that the decision leaves third-party doctrine intact. Instead of avoiding Katz’s pitfalls, moreover, the Court emphasized voluntary assumption of risk, doubling down on the subjective nature of judicial determination. The decision will likely lead to …

Fourth Amendment Constraints On The Technological Monitoring Of Convicted Sex Offenders, Ben A. Mcjunkin, Jj Prescott

Law & Economics Working Papers

More than forty U.S. states currently track at least some of their convicted sex offenders using GPS devices. Many offenders will be monitored for life. The burdens and expense of living indefinitely under constant technological monitoring have been well documented, but most commentators have assumed that these burdens were of no constitutional moment because states have characterized such surveillance as “civil” in character — and courts have seemed to agree. In 2015, however, the Supreme Court decided in Grady v. North Carolina that attaching a GPS monitoring device to a person was a Fourth Amendment search, notwithstanding the ostensibly civil …

Why Courts Fail To Protect Privacy: Race, Age, Bias, And Technology, Christopher Robertson, Bernard Chao, Ian Farrell, Catherine Durso

Faculty Scholarship

The Fourth Amendment protects against unreasonable “searches and seizures,” but in the digital age of stingray devices and IP tracking, what constitutes a search or seizure? The Supreme Court has held that the threshold question is supposed to depend on and reflect the “reasonable expectations” of ordinary members of the public concerning their own privacy. For example, the police now exploit the “third party” doctrine to access data held by email and cell phone providers, without securing a warrant, on the Supreme Court’s intuition that the public has no expectation of privacy in that information. Is that assumption correct? If …

Body Cameras And The Path To Redeem Privacy Law, Woodrow Hartzog

Faculty Scholarship

From a privacy perspective, the movement towards police body cameras seems ominous. The prospect of a surveillance device capturing massive amounts of data concerning people’s most vulnerable moments is daunting. These concerns are compounded by the fact that there is little consensus and few hard rules on how and for whom these systems should be built and used. But in many ways, this blank slate is a gift. Law and policy makers are not burdened by the weight of rules and technologies created in a different time for a different purpose. These surveillance and data technologies will be modern. Many …

Orwell's 1984 And A Fourth Amendment Cybersurveillance Nonintrusion Test, Margaret Hu

Faculty Publications

This Article describes a cybersurveillance nonintrusion test under the Fourth Amendment that is grounded in evolving customary law to replace the reasonable expectation of privacy test formulated in Katz v. United States. To illustrate how customary law norms are shaping modern Fourth Amendment jurisprudence, this Article examines the recurrence of judicial references to George Orwell’s novel, 1984, within the Fourth Amendment context when federal courts have assessed the constitutionality of modern surveillance methods. The Supreme Court has indicated that the Fourth Amendment privacy doctrine must now evolve to impose meaningful limitations on the intrusiveness of new surveillance technologies. …

The drone industry is burgeoning and there is boundless excitement over the potential civil and commercial applications of these aerial observers. Drones are also fun recreational toys that have more capabilities than their predecessor - the remote controlled helicopter. But along with the benefits comes the potential for misuse. More and more frequently concerned spectators are reporting drones flying around the windows of homes, backyards, and at beaches and sporting events. In some places people are even shooting them down.

We have entered a new frontier of aerial observation with the unmanned aircraft. As is often the case with new …
