Anonymity, Faceprints, And The Constitution, Kimberly L. Wehle

All Faculty Scholarship

Part I defines anonymity and explains that respect for the capacity to remain physically and psychologically unknown to the government traces back to the Founding. With the advent and expansion of new technologies such as facial recognition technology (“FRT”), the ability to remain anonymous has eroded, leading to a litany of possible harms.

Part II reviews the existing Fourth and First Amendment doctrine that is available to stave off ubiquitous government surveillance and identifies anonymity as a constitutional value that warrants more explicit doctrinal protection. Although the Fourth Amendment has been construed to excise surveillance of public and third-party information …

When Enough Is Enough: Location Tracking, Mosaic Theory, And Machine Learning, Steven M. Bellovin, Renée M. Hutchins, Tony Jebara, Sebastian Zimmeck

Faculty Scholarship

Since 1967, when it decided Katz v. United States, the Supreme Court has tied the right to be free of unwanted government scrutiny to the concept of reasonable xpectations of privacy.^[1] An evaluation of reasonable expectations depends, among other factors, upon an assessment of the intrusiveness of government action. When making such assessment historically the Court has considered police conduct with clear temporal, geographic, or substantive limits. However, in an era where new technologies permit the storage and compilation of vast amounts of personal data, things are becoming more complicated. A school of thought known as “mosaic theory” …

The Child Independence Is Born: James Otis And Writs Of Assistance, James M. Farrell

Communication

This chapter is a reexamination of the Writs of Assistance speech by James Otis. In particular, it is a reconsideration of the evidence upon which rests the historical reputation of Otis’s address. Are the claims by historians who credit Otis with sparking the Revolutionary movement in colonial America warranted or not? That reassessment begins with a detailed review of the nature and function of writs of assistance within the political, legal, and economic environment of colonial Massachusetts. It then turns to an analysis of the legal dispute over writs of assistance in the 1761 trial. From there we will reconstruct …

Cause To Believe What? The Importance Of Defining A Search's Object--Or, How The Aba Would Analyze The Nsa Metadata Surveillance Program, Christopher Slobogin

Vanderbilt Law School Faculty Publications

Courts and scholars have devoted considerable attention to the definition of probable cause and reasonable suspicion. Since the demise of the mere evidence rule in the 1960s, however, they have rarely examined how these central Fourth Amendment concepts interact with the object of the search. That is unfortunate, because this interaction can have significant consequences. For instance, probable cause to believe that a search might lead to evidence of wrongdoing triggers a very different inquiry than probable cause to believe that a search will produce evidence of criminal activity. The failure to address the constraints that should be imposed on …

Public Assistance, Drug Testing, And The Law: The Limits Of Population-Based Legal Analysis, Candice T. Player

All Faculty Scholarship

In Populations, Public Health and the Law, legal scholar Wendy Parmet urges courts to embrace population-based legal analysis, a public health inspired approach to legal reasoning. Parmet contends that population-based legal analysis offers a way to analyze legal issues—not unlike law and economics—as well as a set of values from which to critique contemporary legal discourse. Population-based analysis has been warmly embraced by the health law community as a bold new way of analyzing legal issues. Still, population-based analysis is not without its problems. At times, Parmet claims too much territory for the population perspective. Moreover, Parmet urges courts …

Failing Expectations: Fourth Amendment Doctrine In The Era Of Total Surveillance, Olivier Sylvain

Faculty Scholarship

Today’s reasonable expectation test and the third-party doctrine have little to nothing to offer by way of privacy protection if users today are at least conflicted about whether transactional noncontent data should be shared with third parties, including law enforcement officials. This uncertainty about how to define public expectation as a descriptive matter has compelled courts to defer to legislatures to find out what public expectation ought to be more as a matter of prudence than doctrine. Courts and others presume that legislatures are far better than courts at defining public expectations about emergent technologies.This Essay argues that the reasonable …

Privacy In Public, Joel R. Reidenberg

Faculty Scholarship

As government and private companies rapidly expand the infrastructure of surveillance from cameras on every street corner to facial recognition for photographs on social media sites, privacy doctrines built on seclusion are at odds with technological advances. This essay addresses a key conceptual problem in US privacy law identified by Justice Sotomayor in U.S. v. Jones and by Justice Scalia in Kyllo v. U.S.; namely that technological capabilities undermine the meaning of the third-party doctrine and the 4th Amendment's ‘reasonable expectation of privacy’ standard. The essay argues that the conceptual problem derives from the evolution of three stages of development …
