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

Orin Kerr

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 …

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

Orin Kerr

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 …

Cell Phones Are Orwell's Telescreen: The Need For Fourth Amendment Protection In Real-Time Cell Phone Location Information, Matthew Devoy Jones

Cleveland State Law Review

Courts are divided as to whether law enforcement can collect cell phone location information in real-time without a warrant under the Fourth Amendment. This Article argues that Carpenter v. United States requires a warrant under the Fourth Amendment prior to law enforcement’s collection of real-time cell phone location information. Courts that have required a warrant prior to the government’s collection of real-time cell phone location information have considered the length of surveillance. This should not be a factor. The growing prevalence and usage of cell phones and cell phone technology, the original intent of the Fourth Amendment, and United States …

Privacy, Freedom, And Technology—Or “How Did We Get Into This Mess?”, Alex Alben

Seattle University Law Review

Can we live in a free society without personal privacy? The question is worth pondering, not only in light of the ongoing debate about government surveillance of private communications, but also because new technologies continue to erode the boundaries of our personal space. This Article examines our loss of freedom in a variety of disparate contexts, all connected by the thread of erosion of personal privacy. In the scenarios explored here, privacy reducing activities vary from government surveillance, personal stalking conducted by individuals, and profiling by data-driven corporations, to political actors manipulating social media platforms. In each case, new technologies …

Hardware, Heartware, Or Nightmare: Smart-City Technology And The Concomitant Erosion Of Privacy, Leila Lawlor

Scholarly Articles

Smart-city technology is being adopted in cities all around the world to simplify our lives, save us time, ease traffic, improve education, reduce energy usage, and keep us healthy and safe. Its adoption is necessary because of changes that are predicted for urban dwellers over the next three decades; urban population and travel are predicted to increase dramatically and our population is graying, meaning the population will include a much greater number of elderly citizens. As these changes occur, smart-city technology can have a huge impact on public safety, improving the ability of law enforcement to investigate crimes, both with …

The Exclusionary Rule In The Age Of Blue Data, Andrew Ferguson

Articles in Law Reviews & Other Academic Journals

In Herring v. United States, Chief Justice John Roberts reframed the Supreme Court’s understanding of the exclusionary rule: “As laid out in our cases, the exclusionary rule serves to deter deliberate, reckless, or grossly negligent conduct, or in some circumstances recurring or systemic negligence.” The open question remains: how can defendants demonstrate sufficient recurring or systemic negligence to warrant exclusion? The Supreme Court has never answered the question, although the absence of systemic or recurring problems has figured prominently in two recent exclusionary rule decisions. Without the ability to document recurring failures, or patterns of police misconduct, courts can dismiss …

Recording As Heckling, Scott Skinner-Thompson

Publications

A growing body of authority recognizes that citizen recording of police officers and public space is protected by the First Amendment. But the judicial and scholarly momentum behind the emerging “right to record” fails to fully incorporate recording’s cost to another important right that also furthers First Amendment principles: the right to privacy.

This Article helps fill that gap by comprehensively analyzing the First Amendment interests of both the right to record and the right to privacy in public while highlighting the role of technology in altering the First Amendment landscape. Recording information can be critical to future speech and, …

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 …
