The Search Of A Search: Moderating Reverse Internet Keyword Warrants, Tui Rademaker

Northwestern University Law Review

Statistics show that Americans consistently turn to Google and other search engines to answer their most personal and private concerns, yet a new investigative tool risks law enforcement having vast discretion in the access of this data. With a keyword warrant, law enforcement can request from a search engine provider (usually Google) a list of probative search queries that users made over a specified time period. Such warrants are beginning to face legal challenges, and so far, courts seem reluctant to recognize the constitutional implications—instead leaving law enforcement with greater potential discretion over their use.

This Note assesses the constitutionality …

“Are We There Yet?”: The Long Journey To Defining Motor Home Protections Under The Fourth Amendment, Ilse Ghent

Arkansas Law Review

From the time of the Revolutionary War, United States citizens have prioritized one thing over almost everything else: that “a man’s house is his castle.” This is immortalized in the Fourth Amendment’s prohibition against unreasonable and warrantless searches. The protections granted by the Fourth Amendment are not centered around the rights a person has in their property. Instead, “the principal object of the Fourth Amendment is the protection of privacy rather than property.” This protection is so important that the Supreme Court has been explicitly clear that warrantless searches should only be permitted in the most “exceptional” of circumstances. One …

Crowdsourcing Surveillance, Chaz Arnett

Faculty Scholarship

In Unreasonable: Black Lives, Police Power, and the Fourth Amendment, Devon W. Carbado illuminates how both the spectacular and quotidian forms of racialized terror, brutality, and surveillance—characteristic of enslavement—have shaped the construction of our constitutional order. He argues that the combined social normalization and legal naturalization of racial hierarchy paved the way for the development of slave patrols and other early iterations of policing where incredible acts of violence against Black bodies were made ordinary and essential. He explains how this legacy continues today with Fourth Amendment jurisprudence not simply failing to protect rights but rather licensing police violence …

Unavoidability In U.S. Privacy Law, Laura M. Moy

Georgetown Law Faculty Publications and Other Works

Why is U.S. privacy law structured the way it is, with a series of sectoral laws rather than a cross-sectoral law or laws? Why does U.S. privacy law protect information shared in certain contexts—such as information shared with an attorney, a healthcare provider, or a financial provider—rather than particular types of information? One possibility is that sectoral laws apply to contexts in which people typically share highly “sensitive” information containing intimate secrets or with the potential to harm them financially or psychologically.

But this Article argues that there is something else at play—that in fact, an under-discussed and underappreciated factor …

When Taint Teams Go Awry: Laundering Unconstitutional Violations Of The Fourth Amendment, Edward S. Adams, William C. Price Jr.

Arkansas Law Review

In this Article, we examine the legal landscape in which taint teams operate, why taint teams are constitutionally problematic, and propose a solution to protect the attorney-client privilege. In Part I, we will first describe what taint teams are supposed to protect—attorney-client privilege. Next, we review how a taint team gets its documents to review, namely the doctrine surrounding (secret) search warrants. Part I ends with a non exhaustive summary of remedies available when attorney-client privilege is violated during searches. In Part II, we explain the current policies and practices surrounding taint teams, including sources of procedure for taint teams …

Warranted Exclusion: A Case For A Fourth Amendment Built On The Right To Exclude, Mailyn Fidler

Law Faculty Scholarship

Searches intrude; fundamentally, they infringe on a right to exclude. So that right should form the basis of Fourth Amendment protections. Current Fourth Amendment doctrine-the reasonable expectation of privacy teststruggles with conceptual clarity and predictability. The Supreme Court's recent decision to overturn Roe v. Wade casts further doubt on the reception of other privacy-based approaches with this Court. But the replacement approach that several Justices on the Court favor, what I call the "maximalist" property approach, risks troublingly narrow results. This Article provides a new alternative: Fourth Amendment protection should be anchored in a flexible concept derived from property law-what …

Life, Liberty, And Data Privacy: The Global Cloud, The Criminally Accused, And Executive Versus Judicial Compulsory Process Powers, Rebecca Wexler

Faculty Scholarship

U.S. policymakers’ responses to a wave of global data privacy laws are creating a deep structural unfairness in the criminal legal system. In an era of cloud computing, when data about communications and activities occurring anywhere in the world can be stored on servers located anywhere else, access to such data can make the difference between convictions and acquittals. At the same time, new global data privacy laws risk cutting off cross-border access to digital evidence in criminal investigations. Recognizing the threat to law enforcement interests, U.S. policymakers enacted the CLOUD Act of 2018 to create special procedures for law …

Persistent Surveillance, Andrew Guthrie Ferguson

Scholarly Articles in Law Reviews & Journals

Persistent surveillance technologies grant police vast new investigative capabilities. The technologies both monitor targeted areas and generate databases of searchable information about people, places, and patterns that can be connected and accessed for criminal prosecutions.

In the face of this growing police surveillance, courts have struggled to make sense of a fragmented Fourth Amendment doctrine. The Supreme Court has offered some clues that “digital may be different” when it comes to surveillance, but lower courts have been left struggling to apply old law to new technologies. Warrantless use of persistent surveillance technologies raises hard questions about when a “search” occurs …

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 …

The Genetic Panopticon: Genetic Genealogy Searches And The Fourth Amendment, Genevieve Carter

Northwestern Journal of Technology and Intellectual Property

As consumer DNA testing gains widespread popularity, so has law enforcement’s interest in leveraging genetic databases for criminal investigations. Consumer DNA testing products like 23andMe and Ancestry allow private individuals access to their genetic data on private databases. However, once coded, genetic data is free to be downloaded by users and uploaded to public databases. Police identify suspects by uploading cold case DNA to public genetic databases and find familial matches. If they identify a familial match, they narrow the field of suspects using traditional methods of investigation, which often includes extracting suspect DNA from a piece of their abandoned …

Revising Reasonableness In The Cloud, Ian Walsh

Washington Law Review

Save everything—just in case––and search for it later. This is a modern mantra fueled by the ubiquity of smartphones, laptops, tablets, and free or low-cost data storage that leads users to store massive amounts of data in the cloud. But when users trust third-party cloud storage providers with private communications, they also surrender Fourth Amendment constitutional certainty. Existing statutory safeguards for these communications are lower than Fourth Amendment warrant and probable cause standards; this permits the government to seize large quantities of users’ private communications stored in the cloud with only minimal justification. Due to the revealing nature of such …

Privacy Asymmetries: Access To Data In Criminal Defense Investigations, Rebecca Wexler

Faculty Scholarship

This Article introduces the phenomenon of “privacy asymmetries,” which are privacy statutes that permit courts to order disclosures of sensitive information when requested by law enforcement but not when requested by criminal defense counsel. In the U.S. adversarial criminal legal system, defense counsel are the sole actors tasked with investigating evidence of innocence. Law enforcement has no constitutional, statutory, or formal ethical duty to seek out evidence of innocence. Therefore, statutes that selectively suppress defense investigations selectively suppress evidence of innocence. Privacy asymmetries form a recurring, albeit previously unrecognized, pattern in privacy statutes. They likely arise from legislative oversight and …

A World Of Difference? Law Enforcement, Genetic Data, And The Fourth Amendment, Christopher Slobogin, J. W. Hazel

Vanderbilt Law School Faculty Publications

Law enforcement agencies are increasingly turning to genetic databases as a way of solving crime, either through requesting the DNA profile of an identified suspect from a database or, more commonly, by matching crime scene DNA with DNA profiles in a database in an attempt to identify a suspect or a family member of a suspect. Neither of these efforts implicates the Fourth Amendment, because the Supreme Court has held that a Fourth Amendment "search" does not occur unless police infringe "expectations of privacy society is prepared to recognize as reasonable" and has construed that phrase narrowly, without reference to …

Trading Privacy For Promotion? Fourth Amendment Implications Of Employers Using Wearable Sensors To Assess Worker Performance, George M. Dery Iii

Northwestern Journal of Law & Social Policy

This Article considers the Fourth Amendment implications of a study on a passive monitoring system where employees shared data from wearables, phone applications, and position beacons that provided private information such as weekend phone use, sleep patterns in the bedroom, and emotional states. The study’s authors hope to use the data collected to create a new system for objectively assessing employee performance that will replace the current system which is plagued by the inherent bias of self-reporting and peer-review and which is labor intensive and inefficient. The researchers were able to successfully link the data collected with the quality of …

The Race For Privacy: Technological Evolution Outpacing Judicial Interpretations Of The Fourth Amendment: Playpen, The Dark Web, And Governmental Hacking, Wade Williams

Florida State University Law Review

Despite complying with the new amendments to Federal Rule of Criminal Procedure 41, the Federal Bureau of Investigation's (FBI) broad authorization to remotely access computers at anytime and anywhere within the United States is at odds with the reasonableness and particularity requirements of the Fourth Amendment. The exponential growth of technology has made life in the twenty-first century something our ancestors would envy, but the idea of allowing the government to perform unknown and undetected searches across the United States, especially in the hidden world of cyberspace, would have our founding fathers turning in their graves. Recognition is owed to …

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 …

Check Yes For Checkpoints: Suspicionless Stops And Ramifications For Missouri Motorists, Conner Harris

Missouri Law Review

One of the great advantages of living in a free society is the enjoyment of general privacy and freedom from unwarranted interference in one’s personal affairs. This advantage benefits citizens in both their private and public interactions. For example, it is expected one could drive to the store across town, the mall in a neighboring city, or somewhere on the other side of the country uninterrupted and unhindered. The Fourth Amendment to the United States Constitution codifies this privacy expectation as a right to be enjoyed by all within its reach. Specifically, the Fourth Amendment protects against “unreasonable searches and …

If You Fly A Drone, So Can Police, Stephen Henderson

Other Faculty Publications

Written for Slate's Future Tense.According to the U.S. Constitution, the more you fly your drone, the more police can fly theirs. “Come on,” you might reply, “that hoary document”—and, yes, sorry to make you the sort who drops words like hoary—“that hoary document surely says nothing about drones.” But in fact it does. At least it does as interpreted by the courts. In particular, it is how they interpret the Fourth Amendment. So, to understand this aspect of drones, we first must understand this provision of the Bill of Rights...

Unilateral Invasions Of Privacy, Roger Allan Ford

Law Faculty Scholarship

Most people seem to agree that individuals have too little privacy, and most proposals to address that problem focus on ways to give those users more information about, and more control over, how information about them is used. Yet in nearly all cases, information subjects are not the parties who make decisions about how information is collected, used, and disseminated; instead, outsiders make unilateral decisions to collect, use, and disseminate information about others. These potential privacy invaders, acting without input from information subjects, are the parties to whom proposals to protect privacy must be directed. This Article develops a theory …

Ou Professor: Fourth Amendment At Heart Of Dispute Between Fbi, Apple, Stephen Henderson

The dispute between the FBI and Apple Inc. over the unlocking of the iPhone used by one of the San Bernadino shooters is important to all Americans. And so it's good that it is getting a wide airing. But when it comes to issues that have complicated tradeoffs, it can be important not just that we have the conversation, but that we use the right words. And here the debate deserves very mixed reviews. . . .

Lawn Signs: A Fourth Amendment For Constitutional Curmudgeons, Andrew Ferguson

Scholarly Articles in Law Reviews & Journals

What is the constitutional significance of the proverbial "keep off the grass" sign? This question — asked by curmudgeonly neighbors everywhere — has been given new currency in a recent decision by the United States Supreme Court. Indeed, Florida v. Jardines might have bestowed constitutional curmudgeons with significant new Fourth Amendment protections. By expressing expectations regarding — and control over — access to property, "the people" may be able to claim greater Fourth Amendment protections not only for their homes, but also for their persons, papers, and effects. This article launches a constitutionally grounded, but lighthearted campaign of citizen education …

Fourth Amendment Time Machines (And What They Might Say About Police Body Cameras), Stephen E. Henderson

Faculty Articles

When it comes to criminal investigation, time travel is increasingly possible. Despite longstanding roots in traditional investigation, science is today providing something fundamentally different in the form of remarkably complete digital records. And those big data records not only store our past, but thanks to data mining they are in many circumstances eerily good at predicting our future. So, now that we stand on the threshold of investigatory time travel, how should the Fourth Amendment and legislation respond? How should we approach bulk government capture, such as by a solar-powered drone employing wide-area persistent stare technology? Is it meaningfully different …
