Privacy In The Age Of Platforms: How Digital Advancements Are Outrunning Our Constitution, Haleigh Fagundes

Capstone Projects and Master's Theses

This project analyzes the procedural history of Fourth Amendment doctrine in the Supreme Court. This timeline begins with the 1928 case of Olmstead v. United States and proceeds with recent cases that resolve more modern concerns such as location tracking via cell-cite information, as seen in Carpenter v. United States (2018). Prevalent cases are analyzed through both majority and dissenting opinions to demonstrate the entire Courts’ attitude towards the interpretation. Though more recently the Court has moved towards expanding the expectation of privacy that one can assume from the Fourth Amendment, digital privacy has yet to be incorporated. The research …

Peeping Town: Drone Surveillance And The Exclusionary Rule In Long Lake Township V. Maxon, Stuart Massa

Northwestern University Law Review

For years, legal commentators have pondered the effect of the Fourth Amendment on drones, but purely as an academic exercise. No court had ever considered drone surveillance under the Fourth Amendment––until now. In Long Lake Township v. Maxon, a northern Michigan township flew a drone over a local resident’s home to gather photographic evidence of an alleged zoning violation. Relying on that evidence, the township sued to enforce its zoning ordinance. The resident moved to suppress the evidence, arguing that the drone’s warrantless surveillance violated the Fourth Amendment. The case made it all the way up to the Michigan …

“Digital Integrity”: Defending The Judicial Integrity In The Digital Age, Guy Alon, Doron Menashe, Guy Itzhak Sender

Touro Law Review

Recent revelations have shown that the protection of the Fourth Amendment in the digital age is inadequate. Despite well-known exclusionary rules regarding evidence obtained by illegal search and seizure, current trends in the digital age and the law of evidence resulted in courts that tend to include such evidence, and by doing so, create significant risk of both substantive and procedural errors and hence increase the potential for wrongful convictions. To address the matter and try to empower and modernize the protection given by the Fourth Amendment, this article suggests performing a revolution in the law of evidence in the …

The Warrant Exception That Isn't: Fisa Section 702, "Defensive" Searches, And The Fourth Amendment, Noah C. Chauvin

Faculty Articles

Section 702 of the Foreign Intelligence Surveillance Act allows the government to conduct warrantless electronic surveillance of non-Americans who are located overseas. Although the surveillance targets foreigners, Americans' communications are "incidentally" collected, too. Once the government has acquired Americans' communications, court-approved rules allow it to conduct warrantless searches for and through them in its Section 702 databases. Intelligence agencies have used these rules to turn this foreign intelligence program into a domestic spying tool, conducting tens of thousands of warrantless "backdoor" searches for Americans' private communications obtained under Section 702 every year.

Section 702 periodically sunsets; Congress most recently reauthorized …

The Evolution Of Surveillance And The Decline Of Privacy, Alan J. Geyer

Honors Undergraduate Theses

This study directly examines how surveillance law and technology have evolved in the United States and how privacy rights have declined correspondingly. The study specifically focuses on how advancements in surveillance technology have overstepped the boundaries of Fourth Amendment protections and analyzes whether these provisions are adequate for protecting citizens in the modern technological era. The study explores newly employed methods of technological surveillance, such as facial recognition, data collection, and automated license plate readers. It focuses on how government surveillance programs have reshaped legal and ethical understandings of privacy. The changes in surveillance and technology have been analyzed by …

Unfenced: The Fourth Circuit Gives Geofencing Its First Appellate Go-Ahead In United States V. Chatrie, Jordan Wallace-Wolf

Washington and Lee Law Review Online

In United States v. Chatrie, the Fourth Circuit issued the first federal appellate opinion on the Fourth Amendment status of geofencing queries. The opinion is significant because geofences present a conceptual challenge to the framework of Carpenter v. United States, the reigning Supreme Court precedent on the Fourth Amendment status of digital searches. That opinion held that long-term tracking of a target individual was a search. However, geofencing reveals information about an indeterminate number of individuals for only a short time, in virtue of their being at a target location during a target span of time. Does the …

Skirting The Fourth Amendment: How Law Enforcement Agencies Abuse Technology And Constitutional Exceptions To Surveille The Public, Matthew Lloyd

Washington and Lee Journal of Civil Rights and Social Justice

Existing Fourth Amendment law does not protect against law enforcement use of data gathered through the internet either by private companies who actively search their customer’s data and submit evidence of misconduct to law enforcement or from private companies who acquire the data on behalf of law enforcement. In an effort to pursue criminals, courts have permitted Fourth Amendment jurisprudence to develop in a manner that permits sweeping invasions of privacy without any probable cause through the private search doctrine or without any procedural protections through the third-party doctrine. It will require substantial judicial or legislative action to return the …

A Miscarriage Of Justice: How Femtech Apps And Fog Data Evade Fourth Amendment Privacy Protections, Rachel Silver

Washington and Lee Journal of Civil Rights and Social Justice

After the fall of Roe v. Wade, states across the country have enacted extreme abortion bans. Anti-abortion states, emboldened by their new, unrestricted power to regulate women’s bodies, are only broadening the scope of abortion prosecutions. And modern technology provides law enforcement with unprecedented access to women’s most intimate information, including, for example, their menstrual cycle, weight, body temperature, sexual activity, mood, medications, and pregnancy details. Fourth Amendment law fails to protect this sensitive information stored on femtech apps from government searches. In a largely unregulated private market, femtech apps sell health and location data to third parties like Fog …

Administrative Regulation Of Programmatic Policing: Why "Leaders Of A Beautiful Struggle" Is Both Right And Wrong, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In Leaders of a Beautiful Struggle v. Baltimore Police Department, the Fourth Circuit Court of Appeals held that Aerial Investigation Research (AIR), Baltimore's aerial surveillance program, violated the Fourth Amendment because it was not authorized by a warrant. AIR was constitutionaly problematic, but not for the reason given by the Fourth Circuit. AIR, like many other technologically-enhanced policing programs that rely on closed-circuit television (CCTV), automated license plate readers and the like, involves the collection and retention of information about huge numbers ofpeople. Because individualized suspicion does not exist with respect to any of these people's information, an individual-specific warrant …

The Empty Promise Of The Fourth Amendment In The Family Regulation System, Anna Arons

Faculty Publications

Each year, state agents search the homes of hundreds of thousands of families across the United States under the auspices of the family regulation system. Through these searches—required elements of investigations into allegations of child maltreatment in virtually every jurisdiction—state agents invade the home, the most protected space in Fourth Amendment jurisprudence. Accordingly, federal courts agree that the Fourth Amendment’s warrant requirement applies to family regulation home searches. But almost universally, the abstract recognition of Fourth Amendment protections runs up against a concrete expectation on the ground that state actors should have easy and expansive access to families’ homes. Legislatures …

Telephone Pole Cameras Under Fourth Amendment Law, Matthew Tokson

Utah Law Faculty Scholarship

In a series of recent cases, police officers have mounted sophisticated surveillance cameras on telephone poles and pointed them at the homes of people suspected of a crime. These cameras often operate for months or even years without judicial oversight, collecting vast quantities of video footage on suspects and their activities near the home. Pole camera surveillance raises important Fourth Amendment questions that have divided courts and puzzled scholars.

These questions are complicated because Fourth Amendment law is complicated. This is especially the case today as Fourth Amendment law is in a transitional phase, caught between older and newer paradigms …

In Celebration Of Dissents (And Lengthy Textbooks): How Digital Became Different For The Fourth Amendment And Why It Is Time For A Real Warrant Default, Stephen E. Henderson

Faculty Articles

The last decade has brought tremendous change to the Fourth Amendment, finally resulting in a ‘digital is different’ norm. We stand at an inflection point between a monolithic, analog past and a murky future of yet-unarticulated constitutional digital policing rules. It is a good time, then, to reflect upon how we came to be here and where we ought to go. This Essay first looks back to a monumental, majestic dissent: that of Justice Louis Brandeis in the 1928 decision of Olmstead v. United States. Every American, and especially every law student, ought to know that opinion, and judges …

Smart Meters As A Catalyst For Privacy Law, Matthew Tokson

Utah Law Faculty Scholarship

Smart utility meters raise several puzzling legal questions—and answering them can help point the way toward the future of Fourth Amendment and civil privacy law. This forum essay addresses two such issues: use restrictions on collected data, and voluntary data disclosure.

First, more than any other current technology, smart meters compel the development of use restrictions on collected data. The benefits of smart meters are potentially enormous, such that categorically prohibiting public utilities from collecting smart meter data is likely beyond the pale. Yet allowing law enforcement agents to obtain detailed or intimate data about the home without a warrant …

Social Norms In Fourth Amendment Law, Matthew Tokson, Ari Ezra Waldman

Michigan Law Review

Courts often look to existing social norms to resolve difficult questions in Fourth Amendment law. In theory, these norms can provide an objective basis for courts’ constitutional decisions, grounding Fourth Amendment law in familiar societal attitudes and beliefs. In reality, however, social norms can shift rapidly, are constantly being contested, and frequently reflect outmoded and discriminatory concepts. This Article draws on contemporary sociological literatures on norms and technology to reveal how courts’ reliance on norms leads to several identifiable errors in Fourth Amendment jurisprudence.

Courts assessing social norms generally adopt what we call the closure principle, or the idea that …

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 …

Cell-Site Location Information And The Privacies Of Life: The Impact Of Carpenter V. United States, Trevor Moore

Limited Privacy In “Pings:” Why Law Enforcement’S Use Of Cell-Site Simulators Does Not Categorically Violate The Fourth Amendment, Lara M. Mcmahon

Washington and Lee Law Review

This Note proposes four factors courts should consider when asked to determine whether law enforcement’s use of a cell-site simulator constituted a Fourth Amendment search. The first asks courts to consider whether the cell-site simulator surveillance infringed on a constitutionally protected area, such as the home. The second asks courts to consider the duration of the cell-site simulator surveillance. The third asks courts to consider whether the cell-site simulator surveillance was conducted actively or passively. The fourth asks courts to focus on the nature and depth of the information obtained as a result of the cell-site simulator surveillance. If, after …

42nd Annual Foulston-Siefkin Lecture: The Next Wave Of Fourth Amendment Challenges After Carpenter, Matthew Tokson

Utah Law Faculty Scholarship

This is an edited and adapted version of the 42nd Annual Foulston Siefkin Lecture, delivered at Washburn University School of Law.

The lecture discusses the future of Fourth Amendment law following the Supreme Court’s enormously important decision in Carpenter v. United States. It analyzes Carpenter and argues that its detailed account of the privacy harms caused by government surveillance will be its most important legacy. Moreover, the Court’s emphasis on the risk of privacy harm is not a one-off or a sharp break from previous practice. Carpenter is consistent with a long line of Supreme Court decisions ignoring or reshaping …

Protecting Online Privacy In The Digital Age: Carpenter V. United States And The Fourth Amendment’S Third-Party Doctrine, Cristina Del Rosso, Carol M. Bast

Catholic University Journal of Law and Technology

The goal of this paper is to examine the future of the third-party doctrine with the proliferation of technology and the online data we are surrounded with daily, specifically after the Supreme Court’s decision in Carpenter v. United States. It is imperative that individuals do not forfeit their Constitutional guarantees for the benefit of living in a technologically advanced society. This requires an understanding of the modern-day functional equivalents of “papers” and “effects.”

Looking to the future, this paper contemplates solutions on how to move forward in this technology era by scrutinizing the relevancy of the third-party doctrine due …

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 …

Customs, Immigration, And Rights: Constitutional Limits On Electronic Border Searches, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

The warrantless search of travelers’ electronic devices as they enter and exit the United States is rapidly increasing. While the Supreme Court has long recognized a border-search exception to the Fourth Amendment’s warrant requirement, it applies to only two interests: promoting the duty regime and preventing contraband from entering the country; and ensuring that individuals are legally admitted. The government’s recent use of the exception goes substantially beyond these matters. U.S. Customs and Border Protection (CBP) and Immigration and Customs Enforcement (ICE) are using it to search electronic devices, and at times the cloud, for evidence of any criminal activity, …

The Public Information Fallacy, Woodrow Hartzog

Faculty Scholarship

The concept of privacy in “public” information or acts is a perennial topic for debate. It has given privacy law fits. People struggle to reconcile the notion of protecting information that has been made public with traditional accounts of privacy. As a result, successfully labeling information as public often functions as a permission slip for surveillance and personal data practices. It has also given birth to a significant and persistent misconception — that public information is an established and objective concept.

In this article, I argue that the “no privacy in public” justification is misguided because nobody knows what “public” …

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 …

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

Scholarly Articles in Law Reviews & 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 …

Psychosocial Analysis Of An Ethnography At The Cuyahoga County Public Defenders Office, Ernest M. Oleksy

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

Too often, social science majors become jaded with their field of study due to a misperception of the nature of many potential jobs which they are qualified for. Such discord is prevalent amongst undergraduates who strive for work in the criminal justice system. Hollywood misrepresentations become the archetypes of the aforementioned field, leaving out the necessity and ubiquity of accompanying desk work. Still other social science majors struggle to identify theoretical interpretations in praxis.

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 …

Cybersurveillance Intrusions And An Evolving Katz Privacy Test, Margaret Hu

Scholarly Articles

To contextualize why a new approach to the Fourth Amendment is essential, this Article describes two emerging cybersurveillance tools. The first Cybersurveillance tool, Geofeedia, has been deployed by state and local law enforcement. Geofeedia uses a process known as "geofencing" to draw a virtual barrier around a particular geographic region, and then identifies and tracks public social media posts within that region for predictive policing purposes. The second tool, Future Attribute Screening Technology (FAST), is under development by the United States Department of Homeland Security (DHS). FAST is another predictive policing tool that analyzes physiological and behavioral signals with the …

Bulk Biometric Metadata Collection, Margaret Hu

Scholarly Articles

Smart police body cameras and smart glasses worn by law enforcement increasingly reflect state-of-the-art surveillance technology, such as the integration of live-streaming video with facial recognition and artificial intelligence tools, including automated analytics. This Article explores how these emerging cybersurveillance technologies risk the potential for bulk biometric metadata collection. Such collection is likely to fall outside the scope of the types of bulk metadata collection protections regulated by the USA FREEDOM Act of 2015. The USA FREEDOM Act was intended to bring the practice of bulk telephony metadata collection conducted by the National Security Agency (“NSA”) under tighter regulation. In …

Carpenter V. United States And The Fourth Amendment: The Best Way Forward, Stephen E. Henderson

Faculty Articles

We finally have a federal ‘test case.’ In Carpenter v. United States, the Supreme Court is poised to set the direction of the Fourth Amendment in the digital age. The case squarely presents how the twentieth-century third party doctrine will fare in contemporary times, and the stakes could not be higher. This Article reviews the Carpenter case and how it fits within the greater discussion of the Fourth Amendment third party doctrine and location surveillance, and I express a hope that the Court will be both a bit ambitious and a good measure cautious. As for ambition, the Court …

Game Of Drones: Rolling The Dice With Unmanned Aerial Vehicles And Privacy, Rebecca L. Scharf

Scholarly Works

This Article offers a practical three-part test for courts and law enforcement to utilize when faced with drone and privacy issues. Specifically addressing the question: how should courts analyze the Fourth Amendment’s protection against ‘unreasonable searches’ in the context of drones?

The Supreme Court’s Fourth Amendment jurisprudence produced an intricate framework to address issues arising out of the intersection of technology and privacy interests. In prominent decisions, including United States v. Katz, California v. Ciraolo, Kyllo v. United States, and most notably, United States v. Jones, the Court focused on whether the use of a single …
