Making The Most Of United States V. Jones In A Surveillance Society: A Statutory Implementation Of Mosaic Theory, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In the Supreme Court's recent decision in United States v. Jones, a majority of the Justices appeared to recognize that under some circumstances aggregation of information about an individual through governmental surveillance can amount to a Fourth Amendment search. If adopted by the Court, this notion sometimes called "mosaic theory"-could bring about a radical change to Fourth Amendment jurisprudence, not just in connection with surveillance of public movements-the issue raised in Jonesbut also with respect to the government's increasingly pervasive record-mining efforts. One reason the Court might avoid the mosaic theory is the perceived difficulty of implementing it. This article …

Making Rights, Nancy Leong

Sturm College of Law: Faculty Scholarship

By adjudicating cases, courts make constitutional rights. This Article considers the conditions under which this constitutional rights-making should take place. Ideally, constitutional rights-making should occur simultaneously in multiple remedial, factual, and procedural contexts; in reality, however, rights are undesirably confined to a single context. This situation has negative consequences for the endeavor of constitutional rights-making.

As a case study in rights-making, the Article offers a comprehensive quantitative and qualitative analysis of the Fourth Amendment. It presents an original data set cataloging every instance of Fourth Amendment rights-making in the federal appellate courts from 2005 and 2009. That data set shows …

Wiretapping The Internet: The Expansion Of The Communications Assistance To Law Enforcement Act To Extend Government Surveillance, Christa M. Hibbard

Federal Communications Law Journal

Criminal use of the Internet to circumvent traditional government phone wiretaps has inspired the Obama Administration to create a proposal to expand the Communications Assistance to Law Enforcement Act ("CALEA"). CALEA was passed in 1994 to regulate telephone and broadband companies to ensure compliance with standards to enable government wiretapping. The proposed amendment of CALEA would allow the government to require all communications service providers to meet technical standards necessary to comply with a wiretap order. The expansion of CALEA would likely widen its scope to social networking sites, instant messaging, gaming consoles that allow conversation among multiple players, and …

Expectations Of Privacy In Social Media, Stephen E. Henderson

Faculty Articles

This article, which largely tracks my remarks at Mississippi College’s Social Media Symposium, examines expectations of privacy in social media such as weblogs (blogs), Facebook pages, and Twitter tweets. Social media is diverse and ever-diversifying, and while I address some of that complexity, I focus on the core functionality, which provides the groundwork for further conversation as the technology and related social norms develop. As one would expect, just as with our offline communications and other online communications, in some we have an expectation of privacy that is recognized by current law, in some we have an expectation of privacy …

Advisory Adjudication, Girardeau A. Spann

Georgetown Law Faculty Publications and Other Works

The Supreme Court decision in Camreta v. Greene is revealing. The Court first issues an opinion authorizing appeals by prevailing parties in qualified immunity cases, even though doing so entails the issuance of an advisory opinion that is not necessary to resolution of the dispute between the parties. And the Court then declines to reach the merits of the underlying constitutional claim in the case, because doing so would entail the issuance of an advisory opinion that was not necessary to the resolution of the dispute between the parties. The Court's decision, therefore, has the paradoxical effect of both honoring …

Beyond Law Enforcement: Camreta V. Greene, Child Protection Investigations, And The Need To Reform The Fourth Amendment Special Needs Doctrine, Joshua Gupta-Kagan

Faculty Scholarship

The Fourth Amendment “special needs” doctrine distinguishes between searches and seizures that serve the “normal need for law enforcement” and those that serve some other special need, excusing non-law-enforcement searches and seizures from the warrant and probable cause requirements. The United States Supreme Court has never justified drawing this bright line exclusively around law enforcement searches and seizures but not around those that threaten important noncriminal constitutional rights.

Child protection investigations illustrate the problem: millions of times each year, state child protection authorities search families' homes and seize children for interviews about alleged maltreatment. Only a minority of these investigations …

Technological Leap, Statutory Gap, And Constitutional Abyss: Remote Biometric Identification Comes Of Age, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

Federal interest in using facial recognition technology (“FRT”) to collect, analyze, and use biometric information is rapidly growing. Despite the swift movement of agencies and contractors into this realm, however, Congress has been virtually silent on the current and potential uses of FRT. No laws directly address facial recognition—much less the pairing of facial recognition with video surveillance—in criminal law. Limits placed on the collection of personally identifiable information, moreover, do not apply. The absence of a statutory framework is a cause for concern. FRT represents the first of a series of next generation biometrics, such as hand geometry, iris, …

Searching Secrets, Nita A. Farahany

Faculty Scholarship

A Fourth Amendment violation has traditionally involved a physical intrusion such as the search of a house or the seizure of a person or her papers. Today, investigators rarely need to break down doors, rummage through drawers, or invade one’s peace and repose to obtain incriminating evidence in an investigation. Instead, the government may unobtrusively intercept information from electronic files, GPS transmissions, and intangible communications. In the near future, it may even be possible to intercept information directly from suspects’ brains. Courts and scholars have analogized modern searches for information to searches of tangible property like containers and have treated …

Predictive Policing And Reasonable Suspicion, Andrew Ferguson

Scholarly Articles in Law Reviews & Journals

Predictive policing is a new law enforcement strategy to reduce crime by predicting criminal activity before it happens. Using sophisticated computer algorithms to forecast future events from past crime patterns, predictive policing has become the centerpiece of a new smart-policing strategy in several major cities. The initial results have been strikingly successful in reducing crime.This article addresses the Fourth Amendment consequences of this police innovation, analyzing the effect of predictive policing on the concept of reasonable suspicion. This article examines predictive policing in the context of the larger constitutional framework of “prediction” and the Fourth Amendment. Many aspects of current …

Crime-Severity Distinctions And The Fourth Amendment: Reassessing Reasonableness In A Changing World, Jeffrey Bellin

Faculty Publications

A growing body of commentary calls for the Supreme Court to recalibrate its Fourth Amendment jurisprudence in response to technological and social changes that threaten the traditional balance between public safety and personal liberty. This Article joins the discussion, highlighting a largely overlooked consideration that should be included in any modernization of Fourth Amendment doctrine—crime severity.

The Supreme Court emphasizes that “reasonableness” is the “touchstone” of Fourth Amendment analysis. Yet, in evaluating contested searches and seizures, current Fourth Amendment doctrine ignores a key determinant of reasonableness, the crime under investigation. As a result, an invasive search of a suspected murderer …

Notes On Borrowing And Convergence, Robert L. Tsai, Nelson Tebbe

Faculty Scholarship

This is a response to Jennifer E. Laurin, "Trawling for Herring: Lessons in Doctrinal Borrowing and Convergence," 111 Colum. L. Rev. 670 (2011), which analyzes the Supreme Court's resort to tort-based concepts to limit the reach of the Fourth Amendment's exclusionary rule. We press three points. First, there are differences between a general and specific critique of constitutional borrowing. Second, the idea of convergence as a distinct phenomenon from borrowing has explanatory potential and should be further explored. Third, to the extent convergence occurs, it matters whether concerns of judicial administration or political reconstruction are driving doctrinal changes.

The Fourth Amendment Rights Of Children At Home: When Parental Authority Goes Too Far, Kristin Henning

William & Mary Law Review

Although it is virtually undisputed that children have some Fourth Amendment rights independent of their parents, it is equally clear that youth generally receive less constitutional protection than adults. In a search for continuity and coherence in Fourth Amendment jurisprudence involving minors, Professor Henning identifies three guiding principles—context, parental authority, and the minor’s capacity—that weave together children’s rights cases. She argues that parental authority too often prevails over children’srights, even when context and demonstrated capacity would supportaffirmation of those rights. Context involves both the physical settingin which Fourth Amendment protections are sought and the nature of the privacy interest at …

Framing The Fourth, Tracey Maclin, Julia Mirabella

Faculty Scholarship

History is again an important element of the Supreme Court’s Fourth Amendment analysis. In Wyoming v. Houghton, Justice Scalia’s opinion for the Court announced that a historical inquiry is the starting point for every Fourth Amendment case. William Cuddihy’s book on the origins and original meaning of the Fourth Amendment will undoubtedly assist the Justices (and everyone else) in understanding the history of search and seizure law.

Cuddihy’s historical analysis is unprecedented. As Justice O’Connor has described it, Cuddihy’s work is “one of the most exhaustive analyses of the original meaning of the Fourth Amendment ever undertaken.” Cuddihy reviewed thousands …

The U.S. Supreme Court Gets It Right In Arizona V. Gant: Justifications For Rules Protect Constitutional Rights, Shenequa L. Grey

St. Thomas Law Review

The purpose of this article is to demonstrate how the justifications or rationales for legal principles form the basis for compliance with the Fourth Amendment of the United States Constitution; and that therefore, failure to comply with those justifications leads to unconstitutional searches and seizures. Strict compliance with the underlying justifications prevents the courts from circumventing the Constitution by establishing a rule, then expanding it beyond its intended purpose. This article demonstrates and reiterates that compliance with the underlying justifications for establishing rules is essential to protecting individual constitutional rights. In addressing these issues, Part I of this article gives …

Randomization And The Fourth Amendment, Bernard Harcourt, Tracey L. Meares

Faculty Scholarship

Randomized checkpoint searches are generally taken to be the exact antithesis of reasonableness under the Fourth Amendment. In the eyes of most jurists checkpoint searches violate the central requirement of valid Fourth Amendment searches – namely, individualized suspicion. We disagree. In this Article, we contend that randomized searches should serve as the very lodestar of a reasonable search. The notion of "individualized" suspicion is misleading; most suspicion in the modem policing context is group based and not individual specific. Randomized searches by definition are accompanied by a certain level of suspicion. The constitutional issue, we maintain, should not turn on …

The Timely Demise Of The Fourth Amendment Third Party Doctrine, Stephen E. Henderson

Faculty Articles

In what may be a slightly premature obituary, in this response to a forthcoming paper by Matthew Tokson I argue that the Fourth Amendment third party doctrine "has at least taken ill, and it can be hoped it is an illness from which it will never recover." It is increasingly unpopular as a matter of state constitutional law, has long been assailed in scholarship but now thoughtful alternatives are percolating, and it cannot – or at least should not – withstand the pressures which technology and social norms are placing upon it. Even the Supreme Court seems loath to defend …
