Privacy Nicks: How The Law Normalizes Surveillance, Woodrow Hartzog, Evan Selinger, Johanna Gunawan

Faculty Scholarship

Privacy law is failing to protect individuals from being watched and exposed, despite stronger surveillance and data protection rules. The problem is that our rules look to social norms to set thresholds for privacy violations, but people can get used to being observed. In this article, we argue that by ignoring de minimis privacy encroachments, the law is complicit in normalizing surveillance. Privacy law helps acclimate people to being watched by ignoring smaller, more frequent, and more mundane privacy diminutions. We call these reductions “privacy nicks,” like the proverbial “thousand cuts” that lead to death.

Privacy nicks come from the …

Wrong Search At The Wrong Time: Keyword Search Warrants And The Fourth Amendment, Nicole Chan

Articles

This Note will advocate for the view that when presented with the issue, state and federal courts should establish that keyword search warrants are unconstitutional because they violate the Fourth Amendment. Keyword search warrants cannot meet the Fourth Amendment’s requirements of probable cause and particularity because the subjects of the search cannot be identified until after the search is completed. These warrants are unnecessary and have the potential of implicating millions of internet users who have no connection to a crime. This Note will contend that individuals have a reasonable expectation of privacy in their search history data, and that …

Privacy And Property: Constitutional Concerns Of Dna Dragnet Testing, E. Wyatt Jones

Honors Projects

DNA dragnets have attracted both public and scholarly criticisms that have yet to be resolved by the Courts. This review will introduce a modern understanding of DNA analysis, a complete introduction to past and present Fourth and Fourteenth Amendment jurisprudence, and existing suggestions concerning similar issues in legal scholarship. Considering these contexts, this review concludes that a focus on privacy and property at once, with a particular sensitivity to the inseverable relationship between the two interests, is Constitutionally consistent with precedent and the most workable means of answering the question at hand.

Surveillance Technologies And Constitutional Law, Christopher Slobogin, Sarah Brayne

Vanderbilt Law School Faculty Publications

This review focuses on government use of technology to observe, collect, or record potential criminal activity in real-time, as contrasted with “transaction surveillance” that involves government efforts to access already-existing records and exploit Big Data, topics that have been the focus of previous reviews (Brayne 2018, Ridgeway 2018). Even so limited, surveillance technologies come in many guises, including closed-circuit television, automated license plate and facial readers, aerial cameras, and GPS tracking. Also classifiable as surveillance technology are devices such as thermal and electromagnetic imagers that can “see” through walls and clothing. Finally, surveillance includes wiretapping and other forms of communication …

Facial Recognition And The Fourth Amendment, Andrew Ferguson

Articles in Law Reviews & Other Academic Journals

Facial recognition offers a totalizing new surveillance power. Police now have the capability to monitor, track, and identify faces through networked surveillance cameras and datasets of billions of images. Whether identifying a particular suspect from a still photo, or identifying every person who walks past a digital camera, the privacy and security impacts of facial recognition are profound and troubling.

This Article explores the constitutional design problem at the heart of facial recognition surveillance systems. One might hope that the Fourth Amendment – designed to restrain police power and enacted to limit governmental overreach – would have something to say …

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

Articles in Law Reviews & Other Academic 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 …

The Value Of Deviance: Understanding Contextual Privacy, Timothy Casey

Faculty Scholarship

Recent decisions by the Supreme Court in Carpenter v. United States and the Illinois Supreme Court in Rosenbach v. Six Flags Entertainment Corporation signal a shift in the traditional understanding of what exactly is protected by a privacy interest. Carpenter distinguished between a police officer’s observation of a suspect’s location and a perpetual catalogue of a person’s movements obtained through cell site location information (CSLI). The pervasive and vast quantity of information from CSLI exposed a protected privacy interest. In Rosenbach, the Illinois Supreme Court found the unique and personal quality of biometric information meant that consent and disclosure requirements …

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 …

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 …

The Fourth Amendment In A Digital World, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

Fourth Amendment doctrines created in the 1970s and 1980s no longer reflect how the world works. The formal legal distinctions on which they rely—(a) private versus public space, (b) personal information versus third party data, (c) content versus non-content, and (d) domestic versus international—are failing to protect the privacy interests at stake. Simultaneously, reduced resource constraints are accelerating the loss of rights. The doctrine has yet to catch up with the world in which we live. A necessary first step for the Court is to reconsider the theoretical underpinning of the Fourth Amendment, to allow for the evolution of a …

The Internet Of Things And The Fourth Amendment Of Effects, Andrew Ferguson

Articles in Law Reviews & Other Academic Journals

By 2020 there will be billions of “things” connected through the “Internet of Things.” These smart devices built within our homes, cars, smartphones, clothing, and accessories present new possibilities for technological surveillance for law enforcement. This network of smart devices also poses a new challenge for a Fourth Amendment built around “effects.” The constitutional language protecting “persons, houses, papers, and effects” from unreasonable searches and seizures must confront this change. This article addresses how a Fourth Amendment built on old-fashioned “effects” can address a new world when things are no longer just inactive, static objects, but objects that create and …

Riley V. California And The Beginning Of The End For The Third-Party Search Doctrine, David A. Harris

Articles

In Riley v. California, the Supreme Court decided that when police officers seize a smart phone, they may not search through its contents -- the data found by looking into the call records, calendars, pictures and so forth in the phone -- without a warrant. In the course of the decision, the Court said that the rule applied not just to data that was physically stored on the device, but also to data stored "in the cloud" -- in remote sites -- but accessed through the device. This piece of the decision may, at last, allow a re-examination of …

Big Data And Predictive Reasonable Suspicion, Andrew Ferguson

Articles in Law Reviews & Other Academic Journals

The Fourth Amendment requires “reasonable suspicion” to seize a suspect. As a general matter, the suspicion derives from information a police officer observes or knows. It is individualized to a particular person at a particular place. Most reasonable suspicion cases involve police confronting unknown suspects engaged in observable suspicious activities. Essentially, the reasonable suspicion doctrine is based on “small data” – discrete facts involving limited information and little knowledge about the suspect.But what if this small data is replaced by “big data”? What if police can “know” about the suspect through new networked information sources? Or, what if predictive analytics …

Reasonable Expectations Of Privacy Settings: Social Media And The Stored Communications Act, David Thaw, Christopher Borchert, Fernando Pinguelo

Articles

In 1986, Congress passed the Stored Communications Act (“SCA”) to provide additional protections for individuals’ private communications content held in electronic storage by third parties. Acting out of direct concern for the implications of the Third-Party Records Doctrine — a judicially created doctrine that generally eliminates Fourth Amendment protections for information entrusted to third parties — Congress sought to tailor the SCA to electronic communications sent via and stored by third parties. Yet, because Congress crafted the SCA with language specific to the technology of 1986, courts today have struggled to apply the SCA consistently with regard to similar private …

Personal Curtilage: Fourth Amendment Security In Public, Andrew Ferguson

Articles in Law Reviews & Other Academic 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 …

When Enough Is Enough: Location Tracking, Mosaic Theory, And Machine Learning, Steven M. Bellovin, Renée M. Hutchins, Tony Jebara, Sebastian Zimmeck

Faculty Scholarship

Since 1967, when it decided Katz v. United States, the Supreme Court has tied the right to be free of unwanted government scrutiny to the concept of reasonable xpectations of privacy.^[1] An evaluation of reasonable expectations depends, among other factors, upon an assessment of the intrusiveness of government action. When making such assessment historically the Court has considered police conduct with clear temporal, geographic, or substantive limits. However, in an era where new technologies permit the storage and compilation of vast amounts of personal data, things are becoming more complicated. A school of thought known as “mosaic theory” …

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 …

On The 'Considered Analysis' Of Collecting Dna Before Conviction, David H. Kaye

Journal Articles

For nearly a decade, DNA-on-arrest laws eluded scrutiny in the courts. For another five years, they withstood a gathering storm of constitutional challenges. In Maryland v. King, however, Maryland's highest court reasoned that usually fingerprints provide everything police need to establish the true identity of an individual before trial and that the state's interest in finding the perpetrators of crimes by trawling databases of DNA profiles is too "generalized" to support "a warrantless, suspicionless search." The U.S. Supreme Court reacted forcefully. Chief Justice Roberts stayed the Maryland judgment, writing that "given the considered analysis of courts on the other side …

Maryland V. King: Per Se Unreasonableness, The Golden Rule, And The Future Of Dna Databases, David H. Kaye

Journal Articles

In Maryland v. King, the Supreme Court applied a balancing test to uphold a Maryland statute mandating preconviction collection and analysis of DNA from individuals charged with certain crimes. The DNA profiles are limited to an inherited set of DNA sequences that are not known to be functional and that are tokens of individual identity. This invited online essay examines two aspects of an article on the case by Professor Erin Murphy. I question the claim that the case is pivotal in a conceivable abandonment of the per se rule that warrantless, suspicionless searches are unconstitutional unless they fall …

Unraveling The Exclusionary Rule: From Leon To Herring To Robinson - And Back?, David H. Kaye

Journal Articles

The Fourth Amendment exclusionary rule began to unravel in United States v. Leon. The facts were compelling. Why exclude reliable physical evidence from trial when it was not the constable who blundered, but “a detached and neutral magistrate” who misjudged whether probable cause was present and issued a search warrant? Later cases applied the exception for “good faith” mistakes to a police officer who, pursuing a grudge against a suspect, arrested and searched him and his truck on the basis of a false and negligent report from a clerk in another county of an outstand­ing arrest warrant. The California Supreme …

The 'High Crime Area' Question: Requiring Verifiable And Quantifiable Evidence For Fourth Amendment Reasonable Suspicion Analysis, Andrew Ferguson, Damien Bernache

Articles in Law Reviews & Other Academic Journals

This article proposes a legal framework to analyze the "high crime area" concept in Fourth Amendment reasonable suspicion challenges.Under existing Supreme Court precedent, reviewing courts are allowed to consider that an area is a "high crime area" as a factor to evaluate the reasonableness of a Fourth Amendment stop. See Illinois v. Wardlow, 528 U.S. 119 (2000). However, the Supreme Court has never defined a "high crime area" and lower courts have not reached consensus on a definition. There is no agreement on what a "high-crime area" is, whether it has geographic boundaries, whether it changes over time, whether it …

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.

Dna Identification Databases: Legality, Legitimacy, And The Case For Population-Wide Coverage, David H. Kaye, Michael E. Smith

Journal Articles

Over the past decade, law enforcement authorities have amassed huge collections of DNA samples and the identifying profiles derived from them. Large DNA databanks routinely help to identify the guilty and to exonerate the innocent, but as the databanks grow, so do fears about civil liberties. Perhaps the most controversial policy issue in the creation of these databases is the question of coverage: Whose DNA profiles should be stored in them? The possibilities extend from convicted violent sex offenders to all convicted felons, to everyone arrested, to the entire population. This Article questions the rationales for drawing the line at …

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 …

Dna Typing: Emerging Or Neglected Issues, David H. Kaye, Edward J. Imwinkelried

Journal Articles

DNA typing has had a major impact on the criminal justice system. There are hundreds of opinions and thousands of cases dealing with DNA evidence. Yet, at virtually every stage of the process, there are important issues that are just emerging or that have been neglected.

At the investigative stage, courts have barely begun to focus on the legal limitations on the power of the police to obtain samples directly from suspects and to use the data from DNA samples in various ways. Issues such as the propriety of "DNA dragnets" (in which large numbers of individuals in a geographic …
