In the 1970s, the Supreme Court handed down Smith v. Maryland and United States v. Miller, two of the most important Fourth Amendment decisions of the 20th century. In these cases, the Court held that people are not entitled to an expectation of privacy in information they voluntarily provide to third parties. This legal proposition, known as the third-party doctrine, permits the government access to, as a matter of Fourth Amendment law, a vast amount of information about individuals, such as the websites they visit; who they have emailed; the phone numbers they dial; and their utility, banking, and education records, just to name a few. Questions have been raised whether this doctrine is still viable in light of the major technological and social changes over the past several decades.

Winner, 2018 Law & Legal Studies PROSE Award The consequences of big data and algorithm-driven policing and its impact on law enforcement In a high-tech command center in downtown Los Angeles, a digital map lights up with 911 calls, television monitors track breaking news stories, surveillance cameras sweep the streets, and rows of networked computers link analysts and police officers to a wealth of law enforcement intelligence. This is just a glimpse into a future where software predicts future crimes, algorithms generate virtual “most-wanted” lists, and databanks collect personal and biometric information. The Rise of Big Data Policing introduces the cutting-edge technology that is changing how the police do their jobs and shows why it is more important than ever that citizens understand the far-reaching consequences of big data surveillance as a law enforcement tool. Andrew Guthrie Ferguson reveals how these new technologies —viewed as race-neutral and objective—have been eagerly adopted by police departments hoping to distance themselves from claims of racial bias and unconstitutional practices. After a series of high-profile police shootings and federal investigations into systemic police misconduct, and in an era of law enforcement budget cutbacks, data-driven policing has been billed as a way to “turn the page” on racial bias. But behind the data are real people, and difficult questions remain about racial discrimination and the potential to distort constitutional protections. In this first book on big data policing, Ferguson offers an examination of how new technologies will alter the who, where, when and how we police. These new technologies also offer data-driven methods to improve police accountability and to remedy the underlying socio-economic risk factors that encourage crime. The Rise of Big Data Policing is a must read for anyone concerned with how technology will revolutionize law enforcement and its potential threat to the security, privacy, and constitutional rights of citizens. Read an excerpt and interview with Andrew Guthrie Ferguson in The Economist.

When the Founders penned the Fourth Amendment to the Constitution, it was not difficult to identify the “persons, houses, papers, and effects” they meant to protect; nor was it hard to understand what “unreasonable searches and seizures” were. The Fourth Amendment was intended to stop the use of general warrants and writs of assistance and applied primarily to protect the home. Flash forward to a time of digital devices, automobiles, the war on drugs, and a Supreme Court dominated by several decades of the jurisprudence of crime control, and the legal meaning of everything from “effects” to “seizures” has dramatically changed. Michael C. Gizzi and R. Craig Curtis make sense of these changes in The Fourth Amendment in Flux. The book traces the development and application of search and seizure law and jurisprudence over time, with particular emphasis on decisions of the Roberts Court. Cell phones, GPS tracking devices, drones, wiretaps, the Patriot Act, constantly changing technology, and a political culture that emphasizes crime control create new challenges for Fourth Amendment interpretation and jurisprudence. This work exposes the tensions caused by attempts to apply pretechnological legal doctrine to modern problems of digital privacy. In their analysis of the Roberts Court’s relevant decisions, Gizzi and Curtis document the different approaches to the law that have been applied by the justices since the Obama nominees took their seats on the court. Their account, combining law, political science, and history, provides insight into the court’s small group dynamics, and traces changes regarding search and seizure law in the opinions of one of its longest serving members, Justice Antonin Scalia. At a time when issues of privacy are increasingly complicated by technological advances, this overview and analysis of Fourth Amendment law is especially welcome—an invaluable resource as we address the enduring question of how to balance freedom against security in the context of the challenges of the twenty-first century.

“At a time when policing in America is at a crossroads, Barry Friedman provides much-needed insight, analysis, and direction in his thoughtful new book. Unwarranted illuminates many of the often ignored issues surrounding how we police in America and highlights why reform is so urgently needed. This revealing book comes at a critically important time and has much to offer all who care about fair treatment and public safety.” —Bryan Stevenson, founder and Executive Director of the Equal Justice Initiative and author of Just Mercy: A Story of Justice and Redemption In June 2013, documents leaked by Edward Snowden sparked widespread debate about secret government surveillance of Americans. Just over a year later, the shooting of Michael Brown, a black teenager in Ferguson, Missouri, set off protests and triggered concern about militarization of law enforcement and discriminatory policing. In Unwarranted, Barry Friedman argues that these two seemingly disparate events are connected—and that the problem is not so much the policing agencies as it is the rest of us. We allow these agencies to operate in secret and to decide how to police us, rather than calling the shots ourselves. And the courts, which we depended upon to supervise policing, have let us down entirely. Unwarranted tells the stories of ordinary people whose lives were torn apart by policing—by the methods of cops on the beat and those of the FBI and NSA. Driven by technology, policing has changed dramatically. Once, cops sought out bad guys; today, increasingly militarized forces conduct wide surveillance of all of us. Friedman captures the eerie new environment in which CCTV, location tracking, and predictive policing have made suspects of us all, while proliferating SWAT teams and increased use of force have put everyone’s property and lives at risk. Policing falls particularly heavily on minority communities and the poor, but as Unwarranted makes clear, the effects of policing are much broader still. Policing is everyone’s problem. Police play an indispensable role in our society. But our failure to supervise them has left us all in peril. Unwarranted is a critical, timely intervention into debates about policing, a call to take responsibility for governing those who govern us.

This book is an originalist rereading of the Fourth Amendment that reveals when and how contemporary surveillance technologies should be subject to constitutional regulation.

"If you've got nothing to hide," many people say, "you shouldn't worry about government surveillance." Others argue that we must sacrifice privacy for security. But as Daniel J. Solove argues in this important book, these arguments and many others are flawed. They are based on mistaken views about what it means to protect privacy and the costs and benefits of doing so. The debate between privacy and security has been framed incorrectly as a zero-sum game in which we are forced to choose between one value and the other. Why can't we have both? In this concise and accessible book, Solove exposes the fallacies of many pro-security arguments that have skewed law and policy to favor security at the expense of privacy. Protecting privacy isn't fatal to security measures; it merely involves adequate oversight and regulation. Solove traces the history of the privacy-security debate from the Revolution to the present day. He explains how the law protects privacy and examines concerns with new technologies. He then points out the failings of our current system and offers specific remedies. Nothing to Hide makes a powerful and compelling case for reaching a better balance between privacy and security and reveals why doing so is essential to protect our freedom and democracy"--Jacket.

Proactive policing, as a strategic approach used by police agencies to prevent crime, is a relatively new phenomenon in the United States. It developed from a crisis in confidence in policing that began to emerge in the 1960s because of social unrest, rising crime rates, and growing skepticism regarding the effectiveness of standard approaches to policing. In response, beginning in the 1980s and 1990s, innovative police practices and policies that took a more proactive approach began to develop. This report uses the term "proactive policing" to refer to all policing strategies that have as one of their goals the prevention or reduction of crime and disorder and that are not reactive in terms of focusing primarily on uncovering ongoing crime or on investigating or responding to crimes once they have occurred. Proactive policing is distinguished from the everyday decisions of police officers to be proactive in specific situations and instead refers to a strategic decision by police agencies to use proactive police responses in a programmatic way to reduce crime. Today, proactive policing strategies are used widely in the United States. They are not isolated programs used by a select group of agencies but rather a set of ideas that have spread across the landscape of policing. Proactive Policing reviews the evidence and discusses the data and methodological gaps on: (1) the effects of different forms of proactive policing on crime; (2) whether they are applied in a discriminatory manner; (3) whether they are being used in a legal fashion; and (4) community reaction. This report offers a comprehensive evaluation of proactive policing that includes not only its crime prevention impacts but also its broader implications for justice and U.S. communities.

How should we think about the problems of privacy and free speech? Neil Richards argues that when privacy and free speech truly conflict, free speech should almost always win, but contends that, contrary to conventional wisdom, speech and privacy are only rarely in conflict.

This book introduces the future of criminal law. It covers every aspect of crime in the digital age, assembled together for the first time. Topics range from Internet surveillance law and the Patriot Act to computer hacking laws and the Council of Europe cybercrime convention. More and more crimes involve digital evidence, and computer crime law will be an essential area for tomorrow's criminal law practitioners. Many U.S. Attorney's Offices have started computer crime units, as have many state Attorney General offices, and any student with a background in this emerging area of law will have a leg up on the competition. This is the first law school book dedicated entirely to computer crime law. The materials are authored entirely by Orin Kerr, a new star in the area of criminal law and Internet law who has recently published articles in the Harvard Law Review, Columbia Law Review, NYU Law Review, and Michigan Law Review. The book is filled with ideas for future scholarship, including hundreds of important questions that have never been addressed in the scholarly literature. The book reflects the author's practice experience, as well: Kerr was a computer crime prosecutor at the Justice Department for three years, and the book combines theoretical insights with practical tips for working with actual cases. Students will find it easy and fun to read, and professors will find it an angaging introduction to a new world of scholarly ideas. The book is ideally suited either for a 2-credit seminar or a 3-credit course, and should appeal both to criminal law professors and those interested in cyberlaw or law and technology. No advanced knowledge of computers and the Internet is required or assumed.
