Notice And Standing In The Fourth Amendment: Searches Of Personal Data, Jennifer Daskal

Scholarly Articles in Law Reviews & Journals

In at least two recent cases, courts have rejected service providers' capacity to raise Fourth Amendment claims on behalf of their customers. These holdings rely on longstanding Supreme Court doctrine establishing a general rule against third parties asserting the Fourth Amendment rights of others. However, there is a key difference between these two recent cases and those cases on which the doctrine rests. The relevant Supreme Court doctrine stems from situations in which someone could take action to raise the Fourth Amendment claim, even if the particular thirdparty litigant could not. In the situations presented by the recent cases, by …

The 'Smart' Fourth Amendment, Andrew Ferguson

Scholarly Articles in Law Reviews & Journals

“Smart” devices radiate data, detailing a continuous, intimate, and revealing pattern of daily life. Billions of sensors will soon collect data from smartphones, smart homes, smart cars, medical devices and an evolving assortment of consumer and commercial products. But, what are these data trails to the Fourth Amendment? Does data emanating from devices on or about our bodies, houses, things, and digital effects fall within the Fourth Amendment’s protection of “persons, homes, papers, or effects”? Does interception of this information violate a “reasonable expectation of privacy?”The “Internet of Things” and the growing proliferation of smart devices create new opportunities for …

Policing Predictive Policing, Andrew Ferguson

Scholarly Articles in Law Reviews & Journals

Predictive policing is sweeping the nation, promising the holy grail of policing – preventing crime before it happens. Police have embraced predictive analytics and data-driven metrics to improve law enforcement tactics, practice, and strategy. Predictive “hot spots” become targets for intensive police surveillance. Targeted “hot people” become suspects. In big cities and small towns, data-based predictions drive police patrol schedules. Risk assessment algorithms target suspicious individuals. Increased data collection fuels a growing feedback loop requiring more robust data crunching systems.All of these predictive innovations share one thing in common: a belief that crime can be understood by identifying and analyzing …

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 …

Mass Suppression: Aggregation And The Fourth Amendment, Nirej Sekhon

Georgia Law Review

The FourthAmendment's exclusionary rule requires that
criminal courts suppress evidence obtained as a result of
an unconstitutionalsearch or seizure. The Supreme Court
has repeatedly stated that suppression is purely
regulatory, not remedial. Its only purpose is to deter
future police misconduct, not to remedy past privacy or
liberty harms suffered by the defendant. Exclusion, in
other words, is for the benefit of community members who
might, sometime in the future, be subject to police
misconduct like that endured by the defendant.
Exclusion's regulatory purpose would be greatly aided if
criminal courts could identify when a suppression motion
involved Fourth Amendment …

Simon Didn't Say: When Reconstruction Of A Private Search Goes Awry Under The Private Search Doctrine, John G. Chambers

Georgia Law Review

A privateparty conducting an unreasonablesearch of an
individual need not fear the Fourth Amendment as the
proscriptions therein are applicable against only the
government. The government, however, need not fear the
Fourth Amendment where it replicates that private party's
unreasonable search. As such, the Fourth Amendment is
not offended where the government directs the private

party to "reconstruct" its initial search. This
reconstruction doctrine breeds many questions in
application, particularly in the digital context. In
grappling with these questions, this Note demonstrates
that the current law provides no satisfying answers. It
proposes a new test to assess reconstructed private party …

Reaching Across The Threshold Of The Fourth Amendment - Why Payton V. New York Should Be Interpreted Broadly, Caroline Hunt

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, …

Cellphones And The Fourth Amendment: Why Cellphone Users Have A Reasonable Expectation Of Privacy In Their Location Information, Paul Cividanes

Journal of Law and Policy

The Fourth Amendment, which affords individuals protection from unreasonable searches and seizures, was ratified over two hundred years ago. As such, it was impossible for the Amendment’s framers to conceive the technologies that exist today. As technology progresses, courts are often faced with the task of deciding how the Fourth Amendment should apply in the modern world. As Fourth Amendment jurisprudence has developed, the Supreme Court has originated tests and doctrines for courts to use when hearing Fourth Amendment challenges to government action. One such test, the ‘reasonable expectation of privacy’ test, looks to see whether an individual has a …

Update On School Searches, Charles J. Russo

Educational Leadership Faculty Publications

School safety continues to present significant challenges for education leaders. Yet as educators work to maintain school safety, boards face a steady stream of litigation because officials have searched students suspected of putting themselves or others in danger. For example, students have been searched because they were suspected of bringing into schools such prohibited items as alcohol, weapons, and drugs.

Education leaders must develop up-to-date policies that ensure safety but that also comply with the Fourth Amendment’s prohibition of unreasonable searches and seizures.

Why Arrest?, Rachel A. Harmon

Michigan Law Review

Arrests are the paradigmatic police activity. Though the practice of arrests in the United States, especially arrests involving minority suspects, is under attack, even critics widely assume the power to arrest is essential to policing. As a result, neither commentators nor scholars have asked why police need to make arrests. This Article takes up that question, and it argues that the power to arrest and the use of that power should be curtailed. The twelve million arrests police conduct each year are harmful not only to the individual arrested but also to their families and communities and to society as …

Policing As Administration, Christopher Slobogin

Vanderbilt Law School Faculty Publications

Police agencies should be governed by the same administrative principles that govern other agencies. This simple precept would have significant implications for regulation of police work, in particular the type of suspicionless, group searches and seizures that have been the subject of the Supreme Court's special needs jurisprudence (practices that this Article calls "panvasive"). Under administrative law principles, when police agencies create statute-like policies that are aimed at largely innocent categories of actors-as they do when administering roadblocks, inspection regimes, drug testing programs, DNA sampling programs, and data collection-they should have to engage in notice-and-comment rulemaking or a similar democratically …

"Reasonable" Police Mistakes: Fourth Amendment Claims And The "Good Faith" Exception After Heien, Karen Mcdonald Henning

St. John's Law Review

(Excerpt)

Given Heien’s distinction between the standard under the Fourth Amendment and the standard for qualified immunity, we are left after Heien with the conclusion that the concept of “objectively reasonable” conduct varies depending on the type of claim the Court is addressing. In particular, Heien leaves open both the question of what constitutes a reasonable mistake of law for Fourth Amendment purposes and the question of how that answer relates to the good faith exception to the exclusionary rule. This Article explores these questions. Part I examines how the Court has increased its tolerance of police mistakes, both in …

Cops On Trial: Did Fourth Amendment Case Law Help George Zimmerman’S Claim Of Self-Defense?, Josephine Ross

Seattle University Law Review

When police kill unarmed civilians, prosecutors and grand juries often decline to bring criminal charges. Even when police officers are indicted, they are seldom convicted at trial. There are many reasons why police are rarely convicted for violent acts. Commentators have criticized the inherent conflict of interest for prosecutors who decide whether to bring charges and the fact that police are investigating their own. However, this article considers another way that police may be treated differently than other people suspected of committing violent crimes. The Fourth Amendment, designed to protect civilians from overzealous officers, now helps insulate police suspected of …

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 …

Making The Grade: School-Based Telemedicine And Parental Consent, Emily G. Narum

San Diego Law Review

This Comment advocates for a uniform state-by-state regulation, requiring schools to obtain parental consent immediately before any telemedicine service is provided to their children at school. Alternatively, the constitutional issues could be eliminated if telemedicine consent forms enumerate a finite and limited list of what medical services may be provided. These reforms will ensure not only that parents’ and children’s constitutional rights are protected, but also that schools and doctors provide the most informed health care services. Part II describes a background of school-based health, as well as the benefits and risks of offering telemedicine in schools. Part III explains …

The Rhetoric Of The Fourth Amendment: Toward A More Persuasive Fourth Amendment, Timothy C. Macdonnell

Washington and Lee Law Review

In the last forty-five years, the United States Supreme Court’s jurisprudence through the lens of classical rhetoric. Opinions are assessed based on three areas of persuasion: appeals to logic (logos); appeals to emotion (pathos); and appeals to credibility (ethos). By examining the Justices’ opinions in this fashion, patterns of unpersuasive opinion writing emerge. While a common source for all unpersuasive opinions is not available, common patterns of weak persuasion in particular appeals do exist. Weak appeals to ethos commonly stem from Justices failing to fully confront the doctrine of stare decisis. Weak pathos-based appeals often involve Justices engaging in misplaced …

Cell Phone Searches After Riley: Establishing Probable Cause And Applying Search Warrant Exceptions, Erica L. Danielsen

Pace Law Review

Part I of this note discusses the Fourth Amendment’s protection against unreasonable search and seizures and its probable cause requirement. The Fourth Amendment’s text remains the same since its enactment. However, interpretation of the Fourth Amendment continues to evolve in order to stay current with society. Interpretation of the Fourth Amendment also varies based on state constitutional law since states can provide its citizens with greater protection than the United States Constitution. This is why the United States Supreme Court, federal district courts, and state courts have all undergone thorough Fourth Amendment analyses when applying the true meaning of the …

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 …

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.

Securing Sequences: Ensuring Adequate Protections For Genetic Samples In The Age Of Big Data, Elizabeth R. Pike

Cardozo Law Review

Bulk collection of our personal data is increasingly common. Our internet browser history leads to personalized, targeted advertising; credit card companies aggregate billions of our collective transactions to gain insight into our spending patterns; and, as recently revealed, the National Security Agency engaged in the widespread collection of our telephone data without our knowledge or consent. But what if the data being collected, stored, shared, and used without our knowledge or consent is arguably the most personal of all data - our unique genetic sequence? In ways underreported and underexamined, the genetic information of nearly every American is likely to …
