Aerial Trespass And The Fourth Amendment, Randall F. Khalil

Michigan Law Review

Since 1973, courts have analyzed aerial surveillance under the Fourth Amendment by applying the test from Katz v. United States, which states that a search triggers the Fourth Amendment when a government actor violates a person’s “reasonable expectation of privacy.” The Supreme Court applied Katz to aerial surveillance three times throughout the 1980s, yet this area of the law remains unsettled and outcomes are unpredictable. In 2012, the Supreme Court recognized an alternative to the Katz test in Jones v. United States, which held that a search triggers the Fourth Amendment when a government actor physically intrudes into …

Another Katz Moment?: Privacy, Property, And A Dna Database, Claire Mena

University of Michigan Journal of Law Reform

The Fourth Amendment protects the “right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.” The understanding of these words seems to shift as new technologies emerge. As law enforcement’s arsenal of surveillance techniques has grown to include GPS tracking, cell phones, and cell site location information (CSLI), the Supreme Court has applied Fourth Amendment protections to these modern tools. Law enforcement continues to use one pervasive surveillance technique without limitations: the routine collection of DNA. In 2013, the Supreme Court in Maryland v. King held that law enforcement may routinely …

The Sacred Fourth Amendment Text, Christopher Slobogin

Michigan Law Review Online

The Supreme Court’s jurisprudence governing the Fourth Amendment’s “threshold”—a word meant to refer to the types of police actions that trigger the amendment’s warrant and reasonableness requirements—has confounded scholars and students alike since Katz v. United States. Before that 1967 decision, the Court’s decisions on the topic were fairly straightforward, based primarily on whether the police trespassed on the target’s property or property over which the target had control. After that decision—which has come to stand for the proposition that a Fourth Amendment search occurs if police infringe an expectation of privacy that society is prepared to recognize as …

How Definitive Is Fourth Amendment Textualism?, Evan H. Caminker

Michigan Law Review Online

Professor Jeffrey Bellin’s excellent article advances a comprehensive and straightforward textual approach to determining what policing activities constitute “searches” triggering the protections of the Fourth Amendment. Bellin’s thesis is that a text-based approach to interpreting the Amendment is superior to the Supreme Court’s current approach, which ever since Katz v. United States has defined “search” primarily by reference to a non-textual “reasonable expectation of privacy” standard. After soundly criticizing the ungrounded and highly subjective nature of the Katz test, Bellin declares that the Court should instead simply follow where the text leads: the Amendment protects people from a search, meaning …

Adapting U.S. Electronic Surveillance Laws, Policies, And Practices To Reflect Impending Technological Developments, Eric Manpearl

Catholic University Law Review

Intelligence collection must always evolve to meet technological developments. While the collection programs under Section 702 of the FISA Amendments Act of 2008 have produced a great deal of valuable intelligence over the last decade, the United States must begin to think about foreseeable technological developments and strategically consider how to conduct signals intelligence (SIGINT) collection in the future.

This Article identifies four technological trends that could significantly impact the way the United States conducts SIGINT. Individuals now have access to sophisticated technologies that formerly only governments seemed capable of creating, and this decentralization of capabilities will likely only increase …

Dna Is Different: An Exploration Of The Current Inadequacies Of Genetic Privacy Protection In Recreational Dna Databases, Jamie M. Zeevi

St. John's Law Review

(Excerpt)

Part I of this Note discusses the fundamental science behind DNA and defines and explains the process of familial DNA searching. Part I also discusses how Carpenter v. United States provides a framework to begin thinking about the unique nature of DNA and privacy implications for its use, and why the revealing nature of this type of data warrants protection. Part II of this Note delves into the lack of constitutional and statutory protections for DNA in recreational DNA databases. First, Part II explains that traditional Fourth Amendment concepts, like search warrants, probable cause, reasonable expectation of privacy, third-party …

Spies In The Skies: Dirtboxes And Airplane Electronic Surveillance, Brian L. Owsley

Michigan Law Review First Impressions

Electronic surveillance in the digital age is essentially a cat-and-mouse game between governmental agencies that are developing new techniques and technologies for surveillance, juxtaposed against privacy rights advocates who voice concerns about such technologies. In November 2014, there was a discovery of a new twist on a relatively old theme. Recently, the Wall Street Journal reported that the U.S. Marshals Service was running a surveillance program employing devices—dirtboxes—that gather all cell phone numbers in the surrounding area. Other federal agencies, including the Drug Enforcement Agency, Immigration and Custom Enforcement, and the Department of Homeland Security, are also documented to have …

The Court Loses Its Way With The Global Positioning System: United States V. Jones Retreats To The “Classic Trespassory Search”, George M. Dery Iii, Ryan Evaro

Michigan Journal of Race and Law

This Article analyzes United States v. Jones, in which the Supreme Court considered whether government placement of a global positioning system (GPS) device on a vehicle to follow a person’s movements constituted a Fourth Amendment “search.” The Jones Court ruled that two distinct definitions existed for a Fourth Amendment “search.” In addition to Katz v. United States’s reasonable-expectation-of-privacy standard, which the Court had used exclusively for over four decades, the Court recognized a second kind of search that it called a “classic trespassory search.” The second kind of search occurs when officials physically trespass or intrude upon a constitutionally protected …

Current And Emerging Transportation Technology: Final Nails In The Coffin Of The Dying Right Of Privacy?, James D. Phillips, Katharine E. Kohm

Richmond Journal of Law & Technology

Transportation networks constitute “the circulatory system of our economy.” The distinct modes that constitute the American transportation system—air, rail, transit, highways, and waterways—impact the entire range of our daily activities. Just as the human body depends on its circulatory system for life and well being, the United States’ vitality would grind to a halting stop without a vibrant transportation system.

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 …

A World Without Privacy: Why Property Does Not Define The Limits Of The Right Against Unreasonable Searches And Seizures, Sherry F. Colb

Michigan Law Review

Imagine for a moment that it is the year 2020. An American company has developed a mind-reading device, called the "brain wave recorder" ("BWR"). The BWR is a highly sensitive instrument that detects electrical impulses from any brain within ten feet of the machine. Though previously thought impossible, the BWR can discern the following information about the target individual: (1) whether he or she is happy, sad, anxious, depressed, or irritable; (2) whether he or she is even slightly sexually aroused; (3) whether he or she is taking any medication (and if so, what the medication is); (4) if a …

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 …

Fbi Internet Surveillance: The Need For A Natural Rights Application Of The Fourth Amendment To Insure Internet Privacy, Catherine M. Barrett

Richmond Journal of Law & Technology

Last year, the Federal Bureau of Investigation (“FBI”) acknowledged that it used an Internet electronic surveillance system called Carnivore to investigate and prosecute criminal suspects in more than two dozen cases. Carnivore is a software program developed by the FBI that can be installed on the network of an Internet Service Provider (“ISP”), such as America Online, to monitor, intercept and collect e-mail messages and other Internet activity made and received by individuals suspected of criminal activity. To date, the full capability of Carnivore remains a secret—the FBI refuses to disclose the source code (computer language) that would reveal how …

Conceptual Foundations Of Privacy: Looking Backward Before Stepping Forward, Robert A. Reilly

Richmond Journal of Law & Technology

In cyberspace, as in today's real world, there seems to be confusion in regard to what privacy is and what it is not. One scholar, Ruth Granson highlights recent efforts to fully comprehend privacy: "the concept of privacy is a central one in most discussions of modern Western life, yet only recently have there been serious efforts to analyze just what is meant by privacy." Over the years, the conception of the nature and extent of privacy has been severely bent out of shape. The definitions and concepts of privacy are as varied as those in the legal and academic …

Privacy Revisited: The Downfall Of Griswald, Martin R. Levy, C. Thomas Hectus

University of Richmond Law Review

This article presents a review of the Supreme Court's privacy decisions since Griswold v. Connecticut, and concentrates on Doe v. Commonwealth's Attorney for City of Richmond as a vehicle to review the Burger Court's trends in the privacy area. Doe is a good vehicle because, though decided without opinion, the summary affirmance of a lower court decision denying homosexuals constitutional protection resolved the tension developing between Douglas' penumbra theory of privacy, which was the opinion of the Court in Griswold, and the more modern substantive due process analysis. The authors conclude that the opinions in Griswold are dead as far …

Reconsideration Of The Katz Expectation Of Privacy Test, Michigan Law Review

Michigan Law Review

This Note, by modifying certain aspects of the reasonable expectation of privacy test, offers a theory that attempts to identify the minimum content of the fourth amendment. In the first section, the Note examines the reasonable expectation of privacy test and considers whether it has been or can be applied in a manner that fails to protect the right to have certain minimum expectations of privacy. It analyzes both the "actual" and the "reasonable" expectation requirements, identifies weaknesses inherent in the current application of these requirements, and suggests certain ways in which they might be refined. In the second section, …
