Network Investigation Techniques: Government Hacking And The Need For Adjustment In The Third-Party Doctrine, Eduardo R. Mendoza

St. Mary's Law Journal

Modern society is largely dependent on technology, and legal discovery is no longer limited to hard-copy, tangible documents. The clash of technology and the law is an exciting, yet dangerous phenomena; dangerous because our justice system desperately needs technological progress. The clash between scientific advancement and the search for truth has recently taken an interesting form—government hacking. The United States Government has increasingly used Network Investigation Techniques (NITs) to target suspects in criminal investigations. NITs operate by identifying suspects who have taken affirmative steps to conceal their identity while browsing the Internet. The hacking technique has become especially useful to …

Knowledge And Fourth Amendment Privacy, Matthew Tokson

Northwestern University Law Review

This Article examines the central role that knowledge plays in determining the Fourth Amendment’s scope. What people know about surveillance practices or new technologies often shapes the “reasonable expectations of privacy” that define the Fourth Amendment’s boundaries. From early decisions dealing with automobile searches to recent cases involving advanced information technologies, courts have relied on assessments of knowledge in a wide variety of Fourth Amendment contexts. Yet the analysis of knowledge in Fourth Amendment law is rarely if ever studied on its own.

This Article fills that gap. It starts by identifying the characteristics of Fourth Amendment knowledge. It finds, …

Tightening The Ooda Loop: Police Militarization, Race, And Algorithmic Surveillance, Jeffrey L. Vagle

Michigan Journal of Race and Law

This Article examines how military automated surveillance and intelligence systems and techniques, when used by civilian police departments to enhance predictive policing programs, have reinforced racial bias in policing. I will focus on two facets of this problem. First, I investigate the role played by advanced military technologies and methods within civilian police departments. These approaches have enabled a new focus on deterrence and crime prevention by creating a system of structural surveillance where decision support relies increasingly upon algorithms and automated data analysis tools and automates de facto penalization and containment based on race. Second, I will explore these …

That ‘70s Show: Why The 11th Circuit Was Wrong To Rely On Cases From The 1970s To Decide A Cell-Phone Tracking Case, David Oscar Markus, Nathan Freed Wessler

University of Miami Law Review

In light of society's increasing reliance on technology, this article explores a critical question – that of the Fourth Amendment’s protection over privacy in the digital age. Specifically, this article addresses how the law currently fails to protect the privacy of one’s cell phone records and its ramifications. By highlighting the antiquated precedent leading up to the Eleventh Circuit’s ruling in United States v. Davis, this article calls on the judiciary to find a more appropriate balance for protecting the right to privacy in a modern society.

Cellphones, Stingrays, And Searches! An Inquiry Into The Legality Of Cellular Location Information, Jeremy H. D'Amico

University of Miami Law Review

Can the Fourth Amendment protect an individual’s right privacy by preventing the disclosure of her location through cell site location information? Does it currently? Should it? Many court opinions answer these questions in both the affirmative and the negative. The rationale underlying each conclusion is disparate. Some rely on statutory regimes, others rely on the United States Supreme Court’s interpretation of reasonableness. However, Cell Site Location Information is a technology that requires uniformity in its interpretation. This note investigates the different interpretations of the Fourth Amendment as it relates to Cell Site Location Information. It explains the technology behind Cell …

Voluntary Disclosure Of Information As A Proposed Standard For The Fourth Amendment's Third-Party Doctrine, Margaret E. Twomey

Michigan Telecommunications & Technology Law Review

The third-party doctrine is a long-standing tenant of Fourth Amendment law that allows law enforcement officers to utilize information that was released to a third party without the probable cause required for a traditional search warrant. This has allowed law enforcement agents to use confidential informants, undercover agents, and access bank records of suspected criminals. However, in a digital age where exponentially more information is shared with Internet Service Providers, e-mail hosts, and social media “friends,” the traditional thirdparty doctrine ideas allow law enforcement officers access to a cache of personal information and data with a standard below probable cause. …

Robots In The Home: What Will We Have Agreed To?, Margot E. Kaminski

Publications

A new technology can expose the cracks in legal doctrine. Sometimes a technology resists analogy. Sometimes, through analogies, it reveals inconsistencies in the law, or basic flaws in framing, or in the fit between different parts of the legal system. This Essay addresses robots in the home, and what they reveal about U.S. privacy law. Household robots might not themselves uproot U.S. privacy law, but they will reveal its inconsistencies, and show where it is most likely to fracture. Just as drones are serving as a legislative “privacy catalyst” — encouraging the enactment of new privacy laws as people realize …

Failing Expectations: Fourth Amendment Doctrine In The Era Of Total Surveillance, Olivier Sylvain

Faculty Scholarship

Today’s reasonable expectation test and the third-party doctrine have little to nothing to offer by way of privacy protection if users today are at least conflicted about whether transactional noncontent data should be shared with third parties, including law enforcement officials. This uncertainty about how to define public expectation as a descriptive matter has compelled courts to defer to legislatures to find out what public expectation ought to be more as a matter of prudence than doctrine. Courts and others presume that legislatures are far better than courts at defining public expectations about emergent technologies.This Essay argues that the reasonable …

Personal Curtilage: Fourth Amendment Security In Public, Andrew Ferguson

Scholarly Articles in Law Reviews & Journals

Do citizens have any Fourth Amendment protection from sense-enhancing surveillance technologies in public? This article engages a timely question as new surveillance technologies have redefined expectations of privacy in public spaces.This article proposes a new theory of Fourth Amendment security based on the ancient theory of curtilage protection for private property. Curtilage has long been understood as a legal fiction that expands the protection of the home beyond the formal structures of the house. Curtilage recognizes a buffer zone beyond the four corners of the home that deserves protection, even in public, even if accessible to public view. Based on …

It’S Raining Katz And Jones: The Implications Of United States V. Jones–A Case Of Sound And Fury, Jace C. Gatewood

Pace Law Review

This Article discusses the implications of Jones in light of emerging technology capable of duplicating the monitoring undertaken in Jones with the same degree of intrusiveness attributable to GPS tracking devices, but without depending on any physical invasion of property. This Article also discusses how the pervasive use of this emerging technology may reshape reasonable expectations of privacy concerning an individual’s public movements, making it all the more difficult to apply the Fourth Amendment constitutional tests outlined in Jones. In this regard, this Article explores recent trends in electronic tracking, surveillance, and other investigative methods that have raised privacy concerns, …

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, …

Searching Secrets, Nita A. Farahany

Faculty Scholarship

A Fourth Amendment violation has traditionally involved a physical intrusion such as the search of a house or the seizure of a person or her papers. Today, investigators rarely need to break down doors, rummage through drawers, or invade one’s peace and repose to obtain incriminating evidence in an investigation. Instead, the government may unobtrusively intercept information from electronic files, GPS transmissions, and intangible communications. In the near future, it may even be possible to intercept information directly from suspects’ brains. Courts and scholars have analogized modern searches for information to searches of tangible property like containers and have treated …

Learning From All Fifty States: How To Apply The Fourth Amendment And Its State Analogs To Protect Third Party Information From Unreasonable Search, Stephen E. Henderson

Faculty Articles

We are all aware of, and many commentators are critical of, the Supreme Court's third-party doctrine, under which information provided to third parties receives no Fourth Amendment protection. This constitutional void becomes increasingly important as technology and social norms dictate that increasing amounts of disparate information are available to third parties. But we are not solely dependent upon the Federal Constitution. We may have more constitutional protection as citizens of states, each of which has a constitutional cognate or analog to the Federal Fourth Amendment. As Justice Brennan urged in a famous 1977 article, those provisions should be interpreted to …

Nothing New Under The Sun? A Technologically Rational Doctrine Of Fourth Amendment Search, Stephen E. Henderson

Faculty Articles

The Fourth Amendment to the United States Constitution prohibits unreasonable searches and seizures. Yet as interpreted by the United States Supreme Court, the Amendment places no restriction on police combing through financial records; telephone, e-mail and website transactional records; or garbage left for collection. Indeed there is no protection for any information knowingly provided to a third party, because the provider is said to retain no reasonable expectation of privacy in that information. As technology dictates that more and more of our personal lives are available to anyone equipped to receive them, and as social norms dictate that more and …

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 …

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 …

Computer Searches And Seizures: Some Unresolved Issues, Susan W. Brenner, Barbara A. Frederiksen

Michigan Telecommunications & Technology Law Review

The goal of this article is to illustrate the issues that arise in the context of computer search and seizures by examining several areas in which the application of Fourth Amendment concepts to computer searches and/or seizures can be problematic. In order to illustrate this point, the article will build on a hypothetical. The hypothetical situation assumes law enforcement officers have lawfully obtained a warrant to search for and seize evidence concerning the commission of one or more crimes. It will also be assumed that computer technology played some role in the commission of these crimes, so computer equipment and …

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 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 …

Your Life As An Open Book: Has Technology Rendered Personal Privacy Virtually Obsolete?, Sandra Byrd Peterson

Federal Communications Law Journal

As society becomes increasingly automated, the ability of individuals to protect their "information privacy" is practically nonexistent. Information that was once kept on paper in filing cabinets is now on-line in computer databases. At the touch of a computer key, a complete stranger can conveniently access and compile from a variety of different sources a dossier of intimate, personal information about people without their knowledge. Perhaps more shocking is the current lack of legal recourse available to contest the nonconsensual use of personal data.

In this Note, the Author examines the currently loose constitutional and common-law protections and suggests strategies …

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.
