Fourth Amendment Remedies As Rights: The Warrant Requirement, David Gray

David C. Gray

The constitutional status of the warrant requirement is hotly debated. Critics argue that neither the text nor history of the Fourth Amendment support a warrant requirement. Also questioned is the warrant requirement’s ability to protect Fourth Amendment interests. Perhaps in response to these concerns, the Court has steadily degraded the warrant requirement through a series of widening exceptions. The result is an unsatisfying jurisprudence that fails on both conceptual and practical grounds.

These debates have gained new salience with the emergence of modern surveillance technologies such as stingrays, GPS tracking, drones, and Big Data. Although a majority of the Court …

Dangerous Dicta, David Gray

David C. Gray

In United States v. Heller, the Court held that individuals have a Second Amendment right to keep and bear arms apart from their associations with state militias. Although that holding was and remains controversial, less attention has been paid to what the Heller Court had to say about the Fourth Amendment. Writing for the Court in Heller, Justice Scalia asserts that the phrase “right of the people” in the Fourth Amendment “unambiguously refers to individual rights, not ‘collective’ rights or rights that may only be exercised through participation in some corporate body.” By any definition, this is dicta. It is …

Addressing The Harm Of Total Surveillance: A Reply To Professor Neil Richards, Danielle Citron, David Gray

David C. Gray

In his insightful article The Dangers of Surveillance, 126 HARV. L. REV. 1934 (2013), Neil Richards offers a framework for evaluating the implications of government surveillance programs that is centered on protecting "intellectual privacy." Although we share his interest in recognizing and protecting privacy as a condition of personal and intellectual development, we worry in this essay that, as an organizing principle for policy, "intellectual privacy" is too narrow and politically fraught. Drawing on other work, we therefore recommend that judges, legislators, and executives focus instead on limiting the potential of surveillance technologies to effect programs of broad and indiscriminate …

The Right To Quantitative Privacy, David Gray, Danielle Citron

David C. Gray

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 …

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

David C. Gray

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 …
