The Missing Algorithm: Safeguarding Brady Against The Rise Of Trade Secrecy In Policing, Deborah Won

Michigan Law Review

Trade secrecy, a form of intellectual property protection, serves the important societal function of promoting innovation. But as police departments across the country increasingly rely on proprietary technologies like facial recognition and predictive policing tools, an uneasy tension between due process and trade secrecy has developed: to fulfill Brady’s constitutional promise of a fair trial, defendants must have access to the technologies accusing them, access that trade secrecy inhibits. Thus far, this tension is being resolved too far in favor of the trade secret holder—and at too great an expense to the defendant. The wrong balance has been struck.

Fourth Amendment Textualism, Jeffrey Bellin

Michigan Law Review

The Fourth Amendment’s prohibition of “unreasonable searches” is one of the most storied constitutional commands. Yet after decades of Supreme Court jurisprudence, a coherent definition of the term “search” remains surprisingly elusive. Even the justices know they have a problem. Recent opinions only halfheartedly apply the controlling “reasonable expectation of privacy” test and its wildly unpopular cousin, “third-party doctrine,” with a few justices in open revolt.

These fissures hint at the Court’s openness to a new approach. Unfortunately, no viable alternatives appear on the horizon. The justices themselves offer little in the way of a replacement. And scholars’ proposals exhibit …

The Mosaic Theory Of The Fourth Amendment, Orin S. Kerr

Michigan Law Review

In the Supreme Court's recent decision on GPS surveillance, United States v. Jones, five justices authored or joined concurring opinions that applied a new approach to interpreting Fourth Amendment protection. Before Jones, Fourth Amendment decisions had always evaluated each step of an investigation individually. Jones introduced what we might call a "mosaic theory" of the Fourth Amendment, by which courts evaluate a collective sequence of government activity as an aggregated whole to consider whether the sequence amounts to a search. This Article considers the implications of a mosaic theory of the Fourth Amendment. It explores the choices and puzzles that …

Katz Is Dead. Long Live Katz, Peter P. Swire

Michigan Law Review

Katz v. United States is the king of Supreme Court surveillance cases. Written in 1967, it struck down the earlier regime of property rules, declaring that "the Fourth Amendment protects people, not places." The concurrence by Justice Harlan announced the new regime - court-issued warrants are required where there is an infringement on a person's "reasonable expectation of privacy." Together with the companion case Berger v. New York, Katz has stood for a grand conception of the Fourth Amendment as a bulwark against wiretaps and other emerging forms of surveillance. Professor Orin Kerr, in his excellent article, shows that …

The Fourth Amendment And New Technologies: Constitutional Myths And The Case For Caution, Orin S. Kerr

Michigan Law Review

To one who values federalism, federal preemption of state law may significantly threaten the autonomy and core regulatory authority of The Supreme Court recently considered whether a1mmg an infrared thermal imaging device at a suspect's home can violate the Fourth Amendment. Kyllo v. United States announced a new and comprehensive rule: the government's warrantless use of senseenhancing technology that is "not in general use" violates the Fourth Amendment when it yields "details of the home that would previously have been unknowable without physical intrusion." Justice Scalia's majority opinion acknowledged that the Court's rule was not needed to resolve the case …

The Legitimation Of Electronic Eavesdropping: The Politics Of "Law And Order", Herman Schwartz

Michigan Law Review

This Article will examine some constitutional considerations raised by wiretapping and eavesdropping in light of recent Supreme Court decisions, the probable extent of such activity, the limitations imposed upon it by title III and the ABA Standards, and the arguments for the "necessity" of electronic surveillance.
