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.

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 …

Declining To State A Name In Consideration Of The Fifth Amendment's Self-Incrimination Clause And Law Enforcement Databases After Hiibel, Joseph R. Ashby

Michigan Law Review

In response to a report of an argument on a public sidewalk, a police officer approaches two people standing in the vicinity of the reported dispute. The officer requests that each person provide her name so the officer can run the names through databases to which the police department subscribes. After searching each name through various databases, the officer might discover that one of the individuals made several purchases of cold medicine containing pseudoephedrine and that the other just received a license from the State to procure certain hazardous chemicals. These two people might be in the early stages of …
