Searches & The Misunderstood History Of Suspicion & Probable Cause: Part One, Fabio Arcila

ExpressO

This article, the first of a two-part series, argues that during the Framers’ era many if not most judges believed they could issue search warrants without independently assessing the adequacy of probable cause, and that this view persisted even after the Fourth Amendment became effective. This argument challenges the leading originalist account of the Fourth Amendment, which Professor Thomas Davies published in the Michigan Law Review in 1999.

The focus in this first article is upon an analysis of the common law and how it reflected the Fourth Amendment’s restrictions. Learned treatises in particular, and to a lesser extent a …

The Liberal Assault On The Fourth Amendment, Christopher Slobogin

ExpressO

The Liberal Assault on the Fourth Amendment Christopher Slobogin As construed by the Supreme Court, the Fourth Amendment’s reasonableness requirement regulates overt, non-regulatory government searches of homes, cars, and personal effects–-and virtually nothing else. This essay is primarily about how we got to this point. It is fashionable to place much of the blame for today’s law on the Warren Court’s adoption of the malleable expectation of privacy concept as the core value protected by the Fourth Amendment. But this diagnosis fails to explain why even the more liberal justices have often gone along with many of the privacy-diminishing holdings …

Detector Dogs And Probable Cause, Richard E. Myers

ExpressO

In this Article, Professor Myers argues that an alert, even by a well-trained dog with an excellent track record in the field, cannot by itself constitute probable cause to search. By using a Bayesian analysis of the value of dog alerts, he demonstrates that additional evidence is needed before probable cause exists. He shows why police won’t make changes to their use of dogs without outside prodding, and explores who might do so. The article makes some suggestions that, if adopted, will improve the courts’ approach to detector dog technologies, allowing them to better strike the balance between the competing …

The Coherence Of Orthodox Fourth Amendment Jurisprudence, Samuel C. Rickless

ExpressO

In the legal academy it is widely believed that the U.S. Supreme Court's orthodox (post-Katz, pre-Houghton) fourth amendment jurisprudence is theoretically incoherent. In particular, the Court has been criticized (on doctrinal and textual grounds) for accepting (i) Justice Harlan's definition of a "search" as an infringement of a subjective expectation of privacy that society is prepared to recognize as reasonable, (ii) the Warrant Requirement and Probable Cause Requirement (according to which searches and seizures without a warrant or probable cause are presumptively unreasonable), and (iii) the Exclusionary Rule (according to which any evidence obtained in violation of a person’s fourth …
