The Right To Quantitative Privacy, Danielle K. Citron, David Gray

Faculty Scholarship

We are at the cusp of a historic shift in our conceptions of the Fourth Amendment driven by dramatic advances in surveillance technology. Governments and their private sector agents continue to invest billions of dollars in massive data-mining projects, advanced analytics, fusion centers, and aerial drones, all without serious consideration of the constitutional issues that these technologies raise. In United States v. Jones, the Supreme Court signaled an end to its silent acquiescence in this expanding surveillance state. In that case, five justices signed concurring opinions defending a revolutionary proposition: that citizens have Fourth Amendment interests in substantial quantities of …

The Fourth Amendment Status Of Stored E-Mail: The Law Professors' Brief In Warshak V. United States, Susan Freiwald, Patricia L. Bellia

Patricia L. Bellia

This paper contains the law professors' brief in the landmark case of Warshak v. United States, the first federal appellate case to recognize a reasonable expectation of privacy in electronic mail stored with an Internet Service Provider (ISP). While the 6th circuit's opinion was subsequently vacated and reheard en banc, the panel decision will remain extremely significant for its requirement that law enforcement agents must generally acquire a warrant before compelling an ISP to disclose its subscriber's stored e-mails. The law professors' brief, co-authored by Susan Freiwald (University of San Francisco) and Patricia L. Bellia (Notre Dame) and signed by …

Fourth Amendment Protection For Stored E-Mail, Patricia L. Bellia, Susan Freiwald

Patricia L. Bellia

The question of whether and how the Fourth Amendment regulates government access to stored e-mail remains open and pressing. A panel of the Sixth Circuit recently held in Warshak v. United States, 490 F.3d 455 (6th Cir. 2007), that users generally retain a reasonable expectation of privacy in the e-mails they store with their Internet Service Providers (ISPs), which implies that government agents must generally acquire a warrant before they may compel ISPs to disclose their users' stored e-mails. The Sixth Circuit, however, is reconsidering the case en banc. This Article examines the nature of stored e-mail surveillance and argues …

Fighting Cybercrime After United States V. Jones, David C. Gray, Danielle Keats Citron, Liz Clark Rinehart

David C. Gray

In a landmark non-decision last term, five Justices of the United States Supreme Court would have held that citizens possess a Fourth Amendment right to expect that certain quantities of information about them will remain private, even if they have no such expectations with respect to any of the information or data constituting that whole. This quantitative approach to evaluating and protecting Fourth Amendment rights is certainly novel and raises serious conceptual, doctrinal, and practical challenges. In other works, we have met these challenges by engaging in a careful analysis of this “mosaic theory” and by proposing that courts focus …

Survey Of Washington Search And Seizure Law: 2013 Update, Justice Charles W. Johnson, Justice Debra L. Stephens

Seattle University Law Review

This survey is intended to serve as a resource to which Washington lawyers, judges, law enforcement officers, and others can turn 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. Many of these cases involve the Washington State Supreme Court’s interpretation of the Washington constitution. Also, as the U.S. Supreme Court has continued to examine Fourth Amendment search and seizure jurisprudence, its …

Down To The Wire: Assessing The Constitutionality Of The National Security Agency's Warrantless Wiretapping Program: Exit The Rule Of Law, Fletcher Baldwin, Robert Shaw

Fletcher N. Baldwin

The article discusses the constitutionality of warrantless wiretapping surveillance by the National Security Agency (NSA) on U.S. citizens. The wiretapping program existed weeks after the September 11, 2001 attacks, on the justification that Congress authorized the president to wiretap U.S. citizens without a warrant, and that the president had inherent authority as commander-in-chief. But it is argued that Congress did not expressly authorize the president to conduct warrantless wiretapping and that he does not have such inherent authority.

We intend this Article to be a commentary on the constitutionality of the NSA wiretapping program solely as it relates to the …

The Not-So-Simple Saga Of Edward And Barack..., Michael I. Niman Ph.D.

Michael I Niman Ph.D.

It reads like a political thriller. An NSA spook, Edward Snowden, meets his conscience, blows the whistle on a massive secret attack on the Fourth Amendment, and is pursued globally by an obsessed president. Spice things up with a bit of character development cross-pollinated with a history lesson. First there’s Darth President. His administration has earned the distinction of invoking the Espionage Act of 1917 (a constitutionally questionable World War One relic) more than all other presidents in the previous 96 years combined—by a factor of two. The Obama administration has charged eight people under the act. All previous administrations …

“Lonesome Road”: Driving Without The Fourth Amendment, Lewis R. Katz

Seattle University Law Review

The protections of the Fourth Amendment on the streets and highways of America have been drastically curtailed. This Article traces the debasement of Fourth Amendment protections on the road and how the Fourth Amendment’s core value of preventing arbitrary police behavior has been marginalized. This Article contends that the existence of a traffic offense should not be the end of the inquiry but the first step, and that defendants should be able to challenge the reasonableness even when there is proof of a traffic offense.

Has Skinner Killed The Katz? Are Society's Expectations Of Privacy Reasonable In Today's Techological World?, Jason Forcier

Jason Forcier

The right to privacy has and will remain a hotly contested debate about American liberties. In 2012, a 3-0 decision by the Sixth Circuit Court of Appeals, in United States v. Melvin Skinner, the court held that there is no “reasonable expectation of privacy in the data given off by. . . cellphone[s].” Given today’s explosion of cellular technology and use of smart phones, is it unreasonable to believe a person should remain secure in their "person" and “effects," as guaranteed under the Fourth Amendment, from unreasonable searches and seizures? Furthermore, with police requiring only a subpoena to a obtain …

A Shattered Looking Glass: The Pitfalls And Potential Of The Mosaic Theory Of Fourth Amendment Privacy, Danielle K. Citron, David Gray

Faculty Scholarship

On January 23, 2012, the Supreme Court issued a landmark non-decision in United States v. Jones. In that case, officers used a GPS-enabled device to track a suspect’s public movements for four weeks, amassing a considerable amount of data in the process. Although ultimately resolved on narrow grounds, five Justices joined concurring opinions in Jones expressing sympathy for some version of the “mosaic theory” of Fourth Amendment privacy. This theory holds that we maintain reasonable expectations of privacy in certain quantities of information even if we do not have such expectations in the constituent parts. This Article examines and explores …

School Security Considerations After Newtown, Jason P. Nance

UF Law Faculty Publications

On December 14, 2012, and in the weeks thereafter, our country mourned the deaths of twenty children and six educators who were brutally shot and killed at Sandy Hook Elementary School in Newtown, Connecticut. Since the horrific massacre, parents, educators, and lawmakers have understandably turned their attention to implementing stronger security measures in schools. This essay provides important points for policymakers and school officials to consider before embarking on a new phase of school security upgrades.

Genetic Privacy & The Fourth Amendment: Unregulated Surreptitious Dna Harvesting, Albert E. Scherr

Georgia Law Review

Genetic privacy and police practices have come to the
fore in the criminal justice system. Case law and stories
in the media document that police are surreptitiously
harvesting the out-of-body DNA of putative suspects.
Some sources even indicate that surreptitious data
banking may also be in its infancy. Surreptitious
harvesting of out-of-body DNA by the police is currently
unregulated by the Fourth Amendment. The few courts
that have addressed the issue find that the police are free
to harvest DNA abandoned by a putative suspect in a
public place. Little in the nascent surreptitious harvesting
case law suggests that surreptitious …

A Spectacular Non Sequitur: The Supreme Court's Contemporary Fourth Amendment Exclusionary Rule Jurisprudence, David C. Gray

Faculty Scholarship

Much of the Supreme Court’s contemporary Fourth Amendment exclusionary rule jurisprudence is constructed upon an analytic mistake that H.L.A. Hart described in another context as a “spectacular non sequitur.” That path to irrelevance is paved by the Court’s recent insistence that the sole justification for excluding evidence seized in violation of the Fourth Amendment is the prospect of deterring law enforcement officers. This deterrence-only approach ignores or rejects more principled justifications that inspired the rule at its genesis and have sustained it through the majority of its history and development. More worrisome, however, is the conceptual insufficiency of deterrence considerations …

Neurotechnologies At The Intersection Of Criminal Procedure And Constitutional Law, Amanda C. Pustilnik

Faculty Scholarship

The rapid development of neurotechnologies poses novel constitutional issues for criminal law and criminal procedure. These technologies can identify directly from brain waves whether a person is familiar with a stimulus like a face or a weapon, can model blood flow in the brain to indicate whether a person is lying, and can even interfere with brain processes themselves via high-powered magnets to cause a person to be less likely to lie to an investigator. These technologies implicate the constitutional privilege against compelled, self-incriminating speech under the Fifth Amendment and the right to be free of unreasonable search and seizure …

On The 'Considered Analysis' Of Collecting Dna Before Conviction, David H. Kaye

Journal Articles

For nearly a decade, DNA-on-arrest laws eluded scrutiny in the courts. For another five years, they withstood a gathering storm of constitutional challenges. In Maryland v. King, however, Maryland's highest court reasoned that usually fingerprints provide everything police need to establish the true identity of an individual before trial and that the state's interest in finding the perpetrators of crimes by trawling databases of DNA profiles is too "generalized" to support "a warrantless, suspicionless search." The U.S. Supreme Court reacted forcefully. Chief Justice Roberts stayed the Maryland judgment, writing that "given the considered analysis of courts on the other side …

Maryland V. King: Per Se Unreasonableness, The Golden Rule, And The Future Of Dna Databases, David H. Kaye

Journal Articles

In Maryland v. King, the Supreme Court applied a balancing test to uphold a Maryland statute mandating preconviction collection and analysis of DNA from individuals charged with certain crimes. The DNA profiles are limited to an inherited set of DNA sequences that are not known to be functional and that are tokens of individual identity. This invited online essay examines two aspects of an article on the case by Professor Erin Murphy. I question the claim that the case is pivotal in a conceivable abandonment of the per se rule that warrantless, suspicionless searches are unconstitutional unless they fall …

The Dog Days Fourth Amendment Jurisprudence, Kit Kinports

Journal Articles

This Article discusses Florida v. Harris and Florida v. Jardines, the two Fourth Amendment drug dog opinions issued by the Supreme Court earlier this year. Together the cases hold that a narcotics detection dog effects a “search” when it intrudes on a constitutionally protected area in order to collect evidence, but that the dog’s positive alert is generally sufficient to support a finding of probable cause. The piece argues that both cases essentially generate a bright-line rule, thereby deviating from precedent that favored a more amorphous standard considering all the surrounding circumstances. Like many purportedly clear rules, the ones …

Culpability, Deterrence, And The Exclusionary Rule, Kit Kinports

Journal Articles

This Article discusses the Supreme Court’s use of the concepts of culpability and deterrence in its Fourth Amendment jurisprudence, in particular, in the opinions applying the good-faith exception to the exclusionary rule. The contemporary Court sees deterrence as the exclusionary rule’s sole function, and the Article begins by taking the Court at its word, evaluating its exclusionary rule case law on its own terms. Drawing on three different theories of deterrence – economic rational choice theory, organizational theory, and the expressive account of punishment – the Article analyzes the mechanics by which the exclusionary rule deters unconstitutional searches and questions …

'Lonesome Road': Driving Without The Fourth Amendment, Lewis R. Katz

Faculty Publications

American states and municipalities have so many minor traffic regulations that every time a driver gets behind the wheel of a car he or she is likely to commit multiple violations. The violation of any traffic regulation empowers police officers to stop the vehicle, ticket and, in some states, arrest the motorist. Police are physically unable to stop and ticket, let alone arrest, every motorist committing a traffic violation. Instead, police are vested with unlimited discretion when choosing which motorists to stop, warn, ticket, or arrest. So long as there is probable cause for a traffic violation, courts will not …

The Exclusionary Rule: Is It On Its Way Out? Should It Be?, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This symposium, comprising six articles in addition to this one, was triggered by a spate of Supreme Court opinions occurring over the last seven years, all of which raise the two questions in the title to this article (which is also the title of the symposium). Since 1974, when United States v. Calandra definitively established deterrence as the primary objective of the suppression remedy, the Court has nibbled away at the exclusionary rule from a number of different directions. But the Court's decisions in Hudson v. Michigan (2006), Herring v. United States (2009), and Davis v. United States (2011) reveal …

Rehnquist And Panvasive Searches, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In the history of the Supreme Court, William Rehnquist may have been the least friendly justice toward the view that the Fourth Amendment should be read expansively. Even he, however, might have interpreted the amendment to place more restrictions on modern law enforcement techniques than current caselaw does. Relying on a 1974 article authored by Rehnquist, this essay, written for a symposium on Rehnquist and the Fourth Amendment, describes his views on the types of requirements the Fourth Amendment imposes on the police, how decriminalization can protect privacy, and most importantly, why Rehnquist might have been willing to regulate surveillance …

Rehnquist's Fourth Amendment: Be Reasonable, Craig M. Bradley

Articles by Maurer Faculty

"The Fourth Amendment: Be Reasonable," is a chapter in a book, The Rehnquist Legacy, published by Cambridge University Press in 2006. The book is a comprehensive legal biography of the Chief Justice in which leading scholars examine his legacy in diverse areas of constitutional law, including criminal procedure. This chapter examines Rehnquist's voluminous Fourth Amendment jurisprudence. While Rehnquist has not authored any single path-breaking case in this area, the chapter shows his success, across the board, in achieving his stated goal of calling a halt to the pro-defendant rulings of the Warren Court in the criminal procedure area. However, Rehnquist …

Passing The Sniff Test: Police Dogs As Surveillance Technology, Irus Braverman

Journal Articles

In October 2012, the Supreme Court of the United States will review the case of Florida v. Jardines, which revolves around the constitutionality of police canine Franky’s sniff outside a private residence. Essentially, the Court will need to decide whether or not the sniff constitutes a “search” for Fourth Amendment purposes. This Article presents a review of the often-contradictory case law that exists on this question to suggest that underlying the various cases is the Courts’ assumption of a juxtaposed relationship between nature and technology. Where dog sniffs are perceived as a technology, the courts have been inclined to also …
