Policing As General Warrants, Warren Buff, Brandon Hasbrouck

Scholarly Articles

The drafters of the Bill of Rights and its proponents envisioned a document constitutionalizing protections against some of the worst abuses they had experienced under English rule. Prominent businessmen—many of them engaged in smuggling— found their homes ransacked in search of contraband on flimsy evidence and without any reason given for the disruption of their business and consequent enrichment of government agents. The Fourth Amendment addressed the use of general warrants and writs of assistance to allow government agents to conduct broad searches with limited scrutiny. In the early years of the Constitution, this had little practical effect, because public …

Unshielded: How The Police Can Become Touchable, Brandon Hasbrouck

Scholarly Articles

This Review proceeds in three Parts. First, Part I examines Shielded’s text, highlighting Schwartz’s analysis of the problem of unaccountable police, the many barriers to holding police accountable, and her proposed solutions. Part II then critically examines Schwartz’s work, examining pieces of the problem she left undiscussed and the relative shortcomings of her discussion of possible solutions. Finally, Part III takes an abolitionist approach, delving into potential nonreformist reforms and the solution of full abolition, as well as examining the most significant objection to abolitionist approaches: the problem of violence.

Who Can Protect Black Protest?, Brandon Hasbrouck

Scholarly Articles

Police violence both as the cause of and response to the racial justice protests following George Floyd’s murder called fresh attention to the need for legal remedies to hold police officers accountable. In addition to the well-publicized issue of qualified immunity, the differential regimes for asserting civil rights claims against state and federal agents for constitutional rights violations create a further barrier to relief. Courts have only recognized damages as a remedy for such abuses in limited contexts against federal employees under the Bivens framework. The history of Black protest movements reveals the violent responses police have to such challenges …

The Unconstitutional Police, Brandon Hasbrouck

Scholarly Articles

Most Fourth Amendment cases arise under a basic fact pattern. Police decide to do something--say, stop and frisk a suspect. They find some crime--say, a gun or drugs--they arrest the suspect, and the suspect is subsequently charged with a crime. The suspect--who is all too often Black--becomes a defendant and challenges the police officers' initial decision as unconstitutional under the Fourth Amendment. The defendant seeks to suppress the evidence against them or perhaps to recover damages for serious injuries under 42 U.S.C. § 1983. The courts subsequently constitutionalize the police officers' initial decision with little or no scrutiny. Effectively, the …

Brief Of Amici Curiae Professors Katherine Mims Crocker And Brandon Hasbrouck In Support Of Neither Party With Respect To Defendant's Motion To Dismiss: Dyer V. Smith, Brandon Hasbrouck, Katherine Mims Crocker

Scholarly Articles

This case illustrates how the First Amendment functions as an essential backstop to Fourth Amendment freedoms—and vice versa. As revealed by the national response to the killing of George Floyd and so many similar injustices, the ability to record encounters with government representatives is critical to preserving civil rights, and especially the right to avoid excessive force. The public only “became aware of the circumstances surrounding George Floyd’s death because citizens standing on a sidewalk exercised their First Amendment rights and filmed a police officer kneeling on Floyd’s neck until he died.” Index Newspapers LLC v. U.S. Marshals Serv., …

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 …

Orwell's 1984 And A Fourth Amendment Cybersurveillance Nonintrusion Test, Margaret Hu

Scholarly Articles

This Article describes a cybersurveillance nonintrusion test under the Fourth Amendment that is grounded in evolving customary law to replace the reasonable expectation of privacy test formulated in Katz v. United States. To illustrate how customary law norms are shaping modern Fourth Amendment jurisprudence, this Article examines the recurrence of judicial references to George Orwell’s novel, 1984, within the Fourth Amendment context when federal courts have assessed the constitutionality of modern surveillance methods. The Supreme Court has indicated that the Fourth Amendment privacy doctrine must now evolve to impose meaningful limitations on the intrusiveness of new surveillance technologies.

Commodifying Policing: A Recipe For Community-Police Tensions, Nora V. Demleitner

Scholarly Articles

This Article, in Part II, begins with a description of how municipalities, at least since the recession of 2008, have fallen short of fully funding their departments. Part III focuses on four distinct outside funding components and their impact on policing. The first subsection discusses asset forfeitures, under both state and federal law. Subsection two highlights revenue derived from citations, often in the form of traffic tickets. A discussion of fees that are being added to fines, often to fund courts, probation agencies, and police departments, follows. The increasing amounts and types of fees imposed have substantially increased the burden …

Biometric Cyberintelligence And The Posse Comitatus Act, Margaret Hu

Scholarly Articles

This Article addresses the rapid growth of what the military and the intelligence community refer to as “biometric-enabled intelligence.” This newly emerging intelligence tool is reliant upon biometric databases—for example, digitalized storage of scanned fingerprints and irises, digital photographs for facial recognition technology, and DNA. This Article introduces the term “biometric cyberintelligence” to more accurately describe the manner in which this new tool is dependent upon cybersurveillance and big data’s massintegrative systems.

This Article argues that the Posse Comitatus Act of 1878, designed to limit the deployment of federal military resources in the service of domestic policies, will be difficult …

Brief Of Scholars Of The History And Original Meaning Of The Fourth Amendment As Amici Curiae In Support Of Petitioner: Carpenter V. United States, Margaret Hu

Scholarly Articles

Law enforcement officials wanted to learn where Petitioner Timothy Carpenter was at the time of certain robberies. To figure that out, they obtained records from his cellular service provider showing the movements of his cell phone. Examining those records, they were able to track Carpenter’s whereabouts over a four-month period. Obtaining and examining those records was a “search” in any normal sense of the word—a search of documents and a search for Carpenter and one of his personal effects. It was therefore a “search” within the meaning of the Fourth Amendment. When the Amendment was ratified, to “search” meant to …

Justice Scalia's Fourth Amendment: Text, Context, Clarity, And Occasional Faint-Hearted Originalism, Timothy C. Macdonnell

Scholarly Articles

Since joining the United States Supreme Court in 1986, Justice Scalia has been a prominent voice on the Fourth Amendment, having written twenty majority opinions, twelve concurrences, and six dissents on the topic. Under his pen, the Court has altered its test for determining when the Fourth Amendment should apply; provided a vision to address technology's encroachment on privacy; and articulated the standard for determining whether government officials are entitled to qualified immunity in civil suits involving alleged Fourth Amendment violations. In most of Justice Scalia's opinions, he has championed an originalist/textualist theory of constitutional interpretation. Based on that theory, …

The Supreme Digital Divide, Mary Graw Leary

Scholarly Articles

Society has long struggled with the meaning of privacy in a modern world. This struggle is not new. With the advent of modern technology and information sharing, however, the challenges have become more complex. Socially, Americans seek to both protect their private lives, and also to utilize technology to connect with the world. Commercially, industries seek to obtain information from individuals, often without their consent, and sell it to the highest bidder. As technology has advanced, the ability of other individuals, institutions, and governments to encroach upon this privacy has strengthened. Nowhere is this tension between individual privacy rights and …

Anti-Justice, Melanie D. Wilson

Scholarly Articles

This Article contends that, despite their unique, ethical duty to “seek justice,” prosecutors regularly fail to fulfill this ethical norm when removed from the traditional, adversarial courtroom setting. Examples abound. For instance, in 2013, Edward Snowden leaked classified information revealing a government-operated surveillance program known as PRISM. That program allows the federal government to collect metadata from phone companies and email accounts and to monitor phone conversations. Until recently, prosecutors relied on some of this covertly acquired intelligence to build criminal cases against American citizens without informing the accused. In failing to notify defendants, prosecutors violated the explicit statutory directives …

Florida V. Jardines: The Wolf At The Castle Door, Timothy C. Macdonnell

Scholarly Articles

The purpose of this article is to examine the controversy regarding the application of the contraband exception to the home and the potential impact of the Florida v. Jardines decision of the U.S. Supreme Court. The article will begin by examining the cases that make up the Supreme Court's contraband exception and some of the Court's precedent regarding the home and warrantless searches. Next, the article will examine the Florida Supreme Court's holding in Jardines and discuss how the Florida court arrived at the conclusion that the canine sniff in that case was a search. This section will compare the …

"You Crossed The Fog Line!"—Kansas, Pretext, And The Fourth Amendment, Melanie D. Wilson

Scholarly Articles

In Whren, the United States Supreme Court sanctioned pretextual traffic stops. In practice the holding of Whren condones police investigations that target certain suspect classes of people, like Hispanics, for increased police scrutiny. In permitting pretextual stops, the Court ignored the risk that such practices will encourage police to distort the truth, overlooked the cost of under-enforcement of the laws, and ignored the consequences to the criminal justice system of race and ethnicity based discrimination.

Kansas law exacerbates these risks by making fog-line stops a model for protecting ulterior motives from a sifting judicial inquiry. In Kansas, it makes …

Improbable Cause: A Case For Judging Police By A More Majestic Standard, Melanie D. Wilson

Scholarly Articles

Several prior studies have demonstrated that police sometimes, if not often, lie in an attempt to avoid the effects of the exclusionary rule. This study of federal trial judges in the District of Kansas suggests that judges may be fostering this police perjury. Judges may unwittingly encourage police perjury because they subconsciously recognize that acknowledging perjury will probably result in release of a culpable defendant. Judges may also permit perjury because they cannot determine when police are lying. In either case, the Supreme Court majority's conception of the exclusionary rule naturally leads trial judges to deny defendants' motions to suppress. …

The Return Of Reasonableness: Saving The Fourth Amendment From The Supreme Court, Melanie D. Wilson

Scholarly Articles

Although there is no recipe for defining Fourth Amendment reasonableness, the Supreme Court produces its most anomalous Fourth Amendment outcomes when it decides "mixed" questions of reasonableness, assessing issues that turn on how ordinary, prudent citizens think and behave. The Court treats these mixed issues, combinations of fact and law, as if they raise purely legal questions. But mixed issues are more complex and require someone to determine historical facts, apply those facts to principles of Fourth Amendment law, and consider the totality of the circumstances, including taking into account community and cultural influences. The Supreme Court will take its …

The Price Of Pretrial Release: Can We Afford To Keep Our Fourth Amendment Rights?, Melanie D. Wilson

Scholarly Articles

The Fourth Amendment serves an important constitutional function. It protects the privacy of Americans from intrusions on their personal security. Few rights are held more sacred. When a person is arrested and faces the real likelihood of pretrial detention in jail, the person risks not only a reduction in his privacy rights, but also a loss of his liberty. In such circumstances, the arrested person should be able to bargain away some of his Fourth Amendment rights in exchange for the additional freedoms associated with release to home.

Undoubtedly, defendants forced to choose between incarceration and Fourth Amendment rights will …

Since When Is Dicta Enough To Trump Fourth Amendment Rights? The Aftermath Of Florida V. J.L., Melanie D. Wilson

Scholarly Articles

Unfortunately for individual liberty, and the inestimable right to personal security, the Supreme Court's extraneous language in its otherwise, well-reasoned decision in Florida v. J.L., and the lower federal courts' interpretation of that extraneous language, have jeopardized the Constitutional right to be free from capricious stops and frivolous frisks, both of which necessarily intrude on the sanctity of the person and sometimes "inflict great indignity and arouse strong resentment . . . ." When read logically and narrowly, the J.L. decision holds that an anonymous telephone tip, alone, does not give law enforcement a sufficient legal basis to stop or …

Police Trespass And The Fourth Amendment: A Wall In Need Of Mending, Clifford S. Fishman

Scholarly Articles

Part I of this article provides an overview of basic Fourth Amendment principles. Part II analyzes the Oliver and Ciraolo cases which define and distinguish residential "curtilage," protected by the Fourth Amendment, and "open fields," which the Fourth Amendment does not protect. Part III reviews the Dow decision's discussion of whether an industrial facility, like a residence, might have constitutionally protected curtilage. Part IV focuses on the Dunn decision, which dramatizes the curtilage-open field dichotomy while at the same time blurring the line between the two. Finally, part V shows how these decisions may have invalidated the "commercial curtilage" concept …

Technologically Enhanced Visual Surveillance And The Fourth Amendment: Sophistication, Availability And The Expectation Of Privacy, Clifford S. Fishman

Scholarly Articles

Since 1983, however, seven Supreme Court decisions have focused at least in part upon application of the Fourth Amendment to technological enhancement of, or technological substitution for, visual surveillance: United States v. Dunn and Texas v. Brown (artificial illumination); United States v. Knotts and United States v. Karo (electronic tracking devices); California v. Ciraolo9 and Florida v. Riley (aerial surveillance); and Dow Chemical Co. v. United States (image-magnifying aerial photography). Reaction to many of these decisions has been highly critical.

In six of the seven cases, investigators refrained from intruding physically into a location protected by the Fourth Amendment. The …

Interception Of Communications In Exigent Circumstances: The Fourth Amendment, Federal Legislation, And The United States Department Of Justice, Clifford S. Fishman

Scholarly Articles

Part I briefly reviews basic Fourth Amendment case law regulating searches and seizures, summarizes the exigent circumstances doctrine, and discusses the applicability of that doctrine to electronic surveillance of communications. Part II outlines Title III's requirements for a "standard" (non-emergency, non-roving) interception order, including what the application and order must contain, and how such an order must be executed. Part III studies the emergency surveillance provision of Title III and reviews Justice Department policies and practices in implementing that provision. Part IV analyzes the new roving intercept provision, discusses its constitutionality, and looks at some practical problems that may arise …

Electronic Tracking Devices And The Fourth Amendment: Knotts, Karo, And The Questions Still Unanswered, Clifford S. Fishman

Scholarly Articles

This article will examine the Knotts and Karo decisions, analyze the unanswered questions relating to the use of electronic tracking devices, and outline legislation that might best resolve those questions and strike a proper balance between the often conflicting values of individual privacy and effective law enforcement.

Pen Registers And Privacy: Risks, Expectations, And The Nullification Of Congressional Intent, Clifford S. Fishman

Scholarly Articles

In United States v. New York Telephone Co. the Supreme Court first ruled that an ordinary search warrant sufficed to authorize law enforcement use of a pen register. Additionally, the Court ruled that a federal district judge possessed the authority to include within the search warrant an order compelling a telephone company to assist the government by installing a pen register on the targeted telephone.

In Smith v. Maryland, the Court considered the legality of pen register surveillance conducted by a telephone company pursuant to an informal police request, that is, without a warrant or other court order. In holding …

The Minimization Requirement In Electronic Surveillance: Title Iii, The Fourth Amendment, And The Dread Scott Decision, Clifford S. Fishman

Scholarly Articles

This article addresses the problems raised by the Title III minimization requirement with particular emphasis on the Supreme Court's decision in Scott. Section I outlines the provisions of Title III that govern the issuance of eavesdropping warrants and the use of derivative evidence. Section II discusses the minimization provision and the definitional problems it presents. Section III analyzes judicial treatment of the minimization provision in light of Scott, and factors that have been held to affect a monitoring agent's ability to minimize interceptions. Section IV discusses judicial approaches to minimization litigation with respect to the problems of standing, guidelines for …
