Signal Lost: Is A Gps Tracking System The Same As An Eyeball?, Eric Andrew Felleman

University of Michigan Journal of Law Reform Caveat

On November 8th, the Supreme Court will hear arguments in United States v. Jones. One of the primary issues in the case is whether law enforcement personnel violated Mr. Jones' Fourth Amendment right to freedom from unreasonable searches and seizures by using a GPS tracking device to monitor the location of his car without a warrant. The 7th Circuit and the 9th Circuit have both recently held that use of GPS tracking is not a search under the Fourth Amendment.

Technological Leap, Statutory Gap, And Constitutional Abyss: Remote Biometric Identification Comes Of Age, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

Federal interest in using facial recognition technology (“FRT”) to collect, analyze, and use biometric information is rapidly growing. Despite the swift movement of agencies and contractors into this realm, however, Congress has been virtually silent on the current and potential uses of FRT. No laws directly address facial recognition—much less the pairing of facial recognition with video surveillance—in criminal law. Limits placed on the collection of personally identifiable information, moreover, do not apply. The absence of a statutory framework is a cause for concern. FRT represents the first of a series of next generation biometrics, such as hand geometry, iris, …

Disentangling Administrative Searches, Eve Brensike Primus

Articles

Everyone who has been screened at an international border, scanned by an airport metal detector, or drug tested for public employment has been subjected to an administrative search. Since September 11th, the government has increasingly invoked the administrative search exception to justify more checkpoints, unprecedented subway searches, and extensive wiretaps. As science and technology advance, the frequency and scope of administrative searches will only expand. Formulating the boundaries and requirements of administrative search doctrine is therefore a matter of great importance. Yet the rules governing administrative searches are notoriously unclear. This Article seeks to refocus attention on administrative searches and …

The Anatomy Of A Search: Intrusiveness And The Fourth Amendment, Renée Mcdonald Hutchins

University of Richmond Law Review

In this essay, I contend that when evaluating the constitutionality of enhanced surveillance devices, the existing test for assessing the occurrence of a Fourth Amendment search should be modified. Specifically, I suggest that intrusiveness should be unambiguously adopted by the Court as the benchmark for assessing and defining the existence of a search under the Fourth Amendment. Moreover, intrusiveness should be clearly defined to require an examination of two factors: the functionality of a challenged form of surveillance and the potential for disclosure created by the device.

Do We Need A New Fourth Amendment?, Orin S. Kerr

Michigan Law Review

Slobogin's book offers a new conceptualization of the Fourth Amendment rooted in what he calls the proportionality principle: An investigative technique should be permitted under the Constitution only if the strength of the government's justification for the technique is roughly proportionate to the level of intrusion it causes . Slobogin roots this principle in Terry v. Ohio and its pragmatic balancing of law-enforcement and privacy interests. To determine how much justification the Fourth Amendment requires, Slobogin argues, courts should assess the intrusiveness of the investigatory technique and then set a proportionate threshold of proof that the government must show. The …

Warrantless Location Tracking, Ian Samuel

Articles by Maurer Faculty

The ubiquity of cell phones has transformed police investigations. Tracking a suspect's movements by following her phone is now a common but largely unnoticed surveillance technique. It is useful, no doubt, precisely because it is so revealing; it also raises significant privacy concerns. In this Note, I consider what the procedural requirements for cell phone tracking should be by examining the relevant statutory and constitutional law. Ultimately, the best standard is probable cause; only an ordinary warrant can satisfy the text of the statutes and the mandates of the Constitution.

Fourth Amendment Protection For Stored E-Mail, Patricia L. Bellia, Susan Freiwald

Journal Articles

The question of whether and how the Fourth Amendment regulates government access to stored e-mail remains open and pressing. A panel of the Sixth Circuit recently held in Warshak v. United States, 490 F.3d 455 (6th Cir. 2007), that users generally retain a reasonable expectation of privacy in the e-mails they store with their Internet Service Providers (ISPs), which implies that government agents must generally acquire a warrant before they may compel ISPs to disclose their users' stored e-mails. The Sixth Circuit, however, is reconsidering the case en banc. This Article examines the nature of stored e-mail surveillance and argues …

Garbage Pails And Puppy Dog Tails: Is That What Katz Is Made Of?, Aya Gruber

Publications

This Article takes the opportunity of the fortieth anniversary of Katz v. U.S. to assess whether the revolutionary case's potential to provide broad and flexible privacy protection to individuals has been realized. Answering this question in a circumspect way, the Article pinpoints the language in Katz that was its eventual undoing and demonstrates how the Katz test has been plagued by two principle problems that have often rendered it more harmful to than protective of privacy. The manipulation problem describes the tendency of conservative courts to define reasonable expectations of privacy as lower than the expectations society actually entertains. The …

Tied Up In Knotts? Gps Technology And The Fourth Amendment, Renée Mcdonald Hutchins

Faculty Scholarship

Judicial and scholarly assessment of emerging technology seems poised to drive the Fourth Amendment down one of three paths. The first would simply relegate the amendment to a footnote in history books by limiting its reach to harms that the framers specifically envisioned. A modified version of this first approach would dispense with expansive constitutional notions of privacy and replace them with legislative fixes. A third path offers the amendment continued vitality but requires the U.S. Supreme Court to overhaul its Fourth Amendment analysis. Fortunately, a fourth alternative is available to cabin emerging technologies within the existing doctrinal framework. Analysis …

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 …

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 …

Applying Pen Register And Trap And Trace Devices To Internet Communications, Rich Haglund

Vanderbilt Journal of Entertainment & Technology Law

This note will explain how the different surveillance methods work: wire taps, pen register and trap and trace devices. It will outline the development of case law and legislation defining what constitutes unlawful searches and seizures involving electronic communications. After explaining how email and internet addresses are collected (and whether the FBI's tool for collection works within the bounds set by the law), this note will discuss the provisions of the Patriot Act that regulate collection of that information. This note will show, using the application of pen register and trap and trace devices to the Internet as an example, …

Marking Carnivore's Territory: Rethinking Pen Registers On The Internet, Anthony E. Orr

Michigan Telecommunications & Technology Law Review

"Carnivore" entered the online world's collective consciousness in June 2000 when the Federal Bureau of Investigation unveiled the Internet surveillance software program to telecommunications industry specialists. The FBI claims the program allows agents to scan the traffic of an Internet Service Provider (ISP) for messages or commands to or from a criminal suspect and then intercept only those messages, capturing copies of e-mails, web site downloads and other file transfers[...] A central issue in the controversy surrounding Carnivore is whether current law permits the FBI to employ the program in the Internet context. Bureau officials claim statutory authority for deployments …

The Founders’ Privacy: The Fourth Amendment And The Power Of Technological Surveillance, Raymond Shih Ray Ku

Faculty Publications

Part I of this Article briefly discusses the history and origins of the Fourth Amendment and its relationship to the doc- trine of separation of powers. Part I argues that the central purpose of the amendment was not to define various aspects of life as private, but to guarantee that the people defined the limits of the executive's surveillance power. Part II then examines the Supreme Court's Fourth Amendment jurisprudence dealing with technology prior to Kyllo, and the problems associated with this jurisprudence. Part II argues that the Supreme Court's framing of the privacy question as whether a new search …

The Magic Lantern Revealed: A Report Of The Fbi's New Key Logging Trojan And Analysis Of Its Possible Treatment In A Dynamic Legal Landscape, Woodrow Hartzog

Faculty Scholarship

Magic Lantern presents several difficult legal questions that are left unanswered due to new or non-existent statutes and case law directly pertaining to the unique situation that Magic Lantern creates. ²⁵ The first concern is statutory. It is unclear what laws, if any, will apply when Magic Lantern is put into use.²⁶ The recent terrorist attacks in the United States have brought the need for information as a matter of national security to the forefront. Congress recently passed legislation (i.e. USA PATRIOT Act) ²⁷ that dramatically modifies current surveillance law, thus further complicating the untested waters of a …

Sex & Surveillance: Gender, Privacy & The Sexualization Of Power In Prison, Teresa A. Miller

Journal Articles

In prison, surveillance is power and power is sexualized. Sex and surveillance, therefore, are profoundly linked. Whereas numerous penal scholars from Bentham to Foucault have theorized the force inherent in the visual monitoring of prisoners, the sexualization of power and the relationship between sex and surveillance is more academically obscure. This article criticizes the failure of federal courts to consider the strong and complex relationship between sex and surveillance in analyzing the constitutionality of prison searches, specifically, cross-gender searches.

The analysis proceeds in four parts. Part One introduces the issues posed by sex and surveillance. Part Two describes the sexually …

The Fourth Amendment: The Right Of The People To Be Secure In Their Persons, Homes, Papers, And Effects, Yale Kamisar

Book Chapters

Three quarters of a century ago, the Supreme Court expressed some thoughts on constitutional interpretation that bear repeating today (Weems v. United States):

Time works changes, brings into existence new conditions and purposes. Therefore, a principle to be vital must be capable of wider application than the mischief which gave it birth. This is particularly true of constitutions .... [In interpreting] a constitution, therefore, our contemplation cannot be only of what has been but what may be. Under any other rule a constitution would indeed be as easyof application as it would be deficient in efficacy and power.

Drug Couriers And The Fourth Amendment: Vanishing Privacy Rights For Commercial Passengers, Alexandra Coulter

Vanderbilt Law Review

Increased drug enforcement initiatives within the United States parallel the international' escalation of the war on drugs. Curbing the flow of narcotics into the country has seemed an unconquerable task.The tremendous influx of illegal substances and the heightened domestic production of both natural and synthetic' drugs prompt governments at every level to attempt to restrict drug trafficking within the United States.' The enforcement escalation is highlighted by a vociferous executive and congressional commitment to the eradication of the drug problem, improved drug detection technology, and a dedication of increased manpower and resources to enforcement efforts.'

Police Use Of Cctv Surveillance: Constitutional Implications And Proposed Regulations, Gary C. Robb

University of Michigan Journal of Law Reform

This article evaluates the constitutionality of CCTV "searches." Part I discusses the present uses being made of closed circuit technology and evaluates the merits of the CCTV surveillance system. The critical policy trade-off is the system's effectiveness in combatting crime against the resulting loss of privacy to individual citizens.

Part II considers the constitutional implications of CCTV use in terms of three major doctrines: the Fourth Amendment prohibition against "unreasonable searches and seizures"; the constitutional right of privacy; and the First Amendment guarantees of free speech and association. This part briefly summarizes the state of the law concerning these constitutional …

Subsequent Use Of Electronic Surveillance Interceptions And The Plain View Doctrine: Fourth Amendment Limitations On The Omnibus Crime Control Act, Raymond R. Kepner

University of Michigan Journal of Law Reform

Despite the critical examination to which many sections of Title III have been subjected, section 2517(5) has received little serious scrutiny from either the courts or the commentators. This note will analyze the constitutionality of the section in terms of the standards which the Supreme Court has articulated, both with respect to the law of search and seizure generally and with respect to electronic surveillance. This examination will reveal that section 2517(5) cannot be sustained under the existing contours of fourth amendment interpretation.

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. Finally, a few jaundiced comments will be offered about legislative and judicial lawmaking in the field of criminal justice, particularly in a time of crisis.
