Carpenter's Legacy: Limiting The Scope Of The Electronic Private Search Doctrine, Sarah A. Mezera

Michigan Law Review

One of the most significant challenges confronting courts and legal scholars in the twenty-first century is the application of Fourth Amendment doctrine to new technology. The circuit split over the application of the private search doctrine to electronic devices exemplifies how courts struggle to apply old doctrines to new circumstances. Some courts take the position that the old doctrine should apply consistently in the new context. Other courts have changed the scope of the old doctrine in order to account for the change in circumstances. The Supreme Court took the latter position in Carpenter v. United States and held that …

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 …

Fourth Amendment Constraints On The Technological Monitoring Of Convicted Sex Offenders, Ben A. Mcjunkin, J. J. Prescott

Articles

More than forty U.S. states currently track at least some of their convicted sex offenders using GPS devices. Many offenders will be monitored for life. The burdens and expense of living indefinitely under constant technological monitoring have been well documented, but most commentators have assumed that these burdens were of no constitutional moment because states have characterized such surveillance as ‘‘civil’’ in character—and courts have seemed to agree. In 2015, however, the Supreme Court decided in Grady v. North Carolina that attaching a GPS monitoring device to a person was a Fourth Amendment search, notwithstanding the ostensibly civil character of …

No More Shortcuts: Protect Cell Site Location Data With A Warrant Requirement, Lauren E. Babst

Michigan Telecommunications & Technology Law Review

In modern society, the cell phone has become a virtual extension of most Americans, managing all kinds of personal and business matters. Modern cell tower technology allows cell service providers to accumulate a wealth of individuals’ location information while they use their cell phones, and such data is available for law enforcement to obtain without a warrant. This is problematic under the Fourth Amendment, which protects reasonable expectations of privacy. Under the Katz two-prong test, (1) individuals have an actual, subjective expectation of privacy in their cell site location data, and (2) society is prepared to acknowledge that expectation as …

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 …

One More Good Reason For In-Car Videotaping Of Traffic Stops: An Accurate Assessment Of "Consent", Robert L. White

University of Michigan Journal of Law Reform Caveat

There are a number of reasons why legislative reform mandating the use of in-car cameras in police cruisers would benefit the criminal justice system in Illinois. In-car cameras provide evidence for cases involving traffic violations or intoxicated motorists. They produce instantly available training materials. They also assist victims of police misconduct, as well as officers defending themselves against misconduct claims. This Comment looks to add to this list of benefits the role in-car cameras can play in assessing the validity of consents to search that officers obtain during traffic stops.

The Latest 4th Amendment Privacy Conundrum: "Stingrays", Max Bulinksi

University of Michigan Journal of Law Reform Caveat

Wired is reporting renewed hubbub regarding statutory and Fourth Amendment protections of individuals’ privacy in the digital age. This time, it comes in the form of federal officers using a fake cellphone tower (called a “stingray”) to locate their suspect, Mr. Rigmaiden, by tracking the location of his cellphone. According to an affidavit submitted to the court, the stingray only captures the equivalent of header information – such as the phone or account number assigned to the aircard as well as dialing, routing and address information involved in the communication.

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.

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 …

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 …

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 …

Technology, Privacy, And The Courts: A Reply To Colb And Swire, Orin S. Kerr

Michigan Law Review

I thank Sherry Colb and Peter Swire for devoting their time and considerable talents to responding to my article, The Fourth Amendment and New Technologies: Constitutional Myths and the Case for Caution. I will conclude with a few comments.

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 …

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.
