Administrative Regulation Of Programmatic Policing: Why "Leaders Of A Beautiful Struggle" Is Both Right And Wrong, Christopher Slobogin Jul 2023

Administrative Regulation Of Programmatic Policing: Why "Leaders Of A Beautiful Struggle" Is Both Right And Wrong, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In Leaders of a Beautiful Struggle v. Baltimore Police Department, the Fourth Circuit Court of Appeals held that Aerial Investigation Research (AIR), Baltimore's aerial surveillance program, violated the Fourth Amendment because it was not authorized by a warrant. AIR was constitutionaly problematic, but not for the reason given by the Fourth Circuit. AIR, like many other technologically-enhanced policing programs that rely on closed-circuit television (CCTV), automated license plate readers and the like, involves the collection and retention of information about huge numbers ofpeople. Because individualized suspicion does not exist with respect to any of these people's information, an individual-specific warrant …


A World Of Difference? Law Enforcement, Genetic Data, And The Fourth Amendment, Christopher Slobogin, J. W. Hazel Jan 2021

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 …


Government Data Mining And The Fourth Amendment, Christopher Slobogin Jan 2008

Government Data Mining And The Fourth Amendment, Christopher Slobogin

Vanderbilt Law School Faculty Publications

The government's ability to obtain and analyze recorded information about its citizens through the process known as data mining has expanded enormously over the past decade. Although the best-known government data mining operation (Total Information Awareness, more recently dubbed Terrorism Information Awareness) supposedly no longer exists, large-scale data mining by federal agencies devoted to enforcing criminal and counter-terrorism laws has continued unabated. This paper addresses three puzzles about data mining. First, when data mining is undertaken by the government, does it implicate the Fourth Amendment? Second, does the analysis change when data mining is undertaken by private entities which then …


The Liberal Assault On The Fourth Amendment, Christopher Slobogin Jan 2007

The Liberal Assault On The Fourth Amendment, Christopher Slobogin

Vanderbilt Law School Faculty Publications

As construed by the Supreme Court, the Fourth Amendment's reasonableness requirement regulates overt, non-regulatory government searches of homes, cars, and personal effects-and virtually nothing else. This essay is primarily about how we got to this point. It is fashionable to place much of the blame for today's law on the Warren Court's adoption of the malleable expectation of privacy concept as the core value protected by the Fourth Amendment. But this diagnosis fails to explain why even the more liberal justices have often gone along with many of the privacy-diminishing holdings of the Court. This essay argues that three other …


Transaction Surveillance By The Government, Christopher Slobogin Jan 2005

Transaction Surveillance By The Government, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This symposium article is the second of two on regulation of government efforts to obtain recorded information for criminal prosecutions. More specifically, it explores the scope and regulation of "transaction surveillance," which it defines as government attempts to access already existing records, either physically or through data banks, and government efforts to obtain, in real-time or otherwise, "catalogic data" (the identifying signals of a transaction, such as the address of an email recipient). Transaction surveillance is a potent way of discovering and making inferences about a person's activities, character and identity. Yet, despite a bewildering array of statutorily created authorization …


The Poverty Exception To The Fourth Amendment, Christopher Slobogin Jan 2003

The Poverty Exception To The Fourth Amendment, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This essay, written for the Sixth Annual LatCrit conference, explores the subterranean motifs of current rules regulating searches and seizures by the police. More specifically, it investigates whether and to what extent alienage, race and poverty influence the warrant and individualized suspicion rules purportedly governing police investigation. The essay begins by showing that, contrary to the assertion of other conference participants, Supreme Court doctrine has not created a "Mexican exception" to the Fourth Amendment (as distinguished from an "illegal alien" exception, which does seem to exist). The main focus of the article, however, is an examination of whether the Court's …


Technologically-Assisted Physical Surveillance: The American Bar Association's Tentative Draft Standards, Christopher Slobogin Jan 1997

Technologically-Assisted Physical Surveillance: The American Bar Association's Tentative Draft Standards, Christopher Slobogin

Vanderbilt Law School Faculty Publications

As the name implies, the American Bar Association's Tentative Draft Standards Concerning Technologically-Assisted Physical Surveillance is a work in progress...Final approval by the ABA hierarchy is still some time away, so feedback could have an impact. Indeed, it is anticipated that the content of at least some of the standards will change prior to their submission to the House of Delegates...The work of the Task Force on Technology and Law Enforcement has persuasively demonstrated that some regulatory structure governing the use of physical surveillance technology is necessary. This work provides a model for future attempts to establish guidelines for other …


World Without A Fourth Amendment, Christopher Slobogin Jan 1991

World Without A Fourth Amendment, Christopher Slobogin

Vanderbilt Law School Faculty Publications

The subject of this Article is suggested by a single question: How would we regulate searches and seizures if the Fourth Amendment did not exist? This question is a useful one to ask even leaving aside the possibility of amending the amendment. Starting on a blank slate, as it were, should free us from current preconceptions about the law of search and seizure, ingrained after years of analyzing current dogma. Viewed from this fresh perspective, we might gain a better understanding of the values at stake when the state seeks to obtain evidence or detain suspects. This new understanding in …


Capacity To Contest A Search And Seizure: The Passing Of Old Rules And Some Suggestions For New Ones, Christopher Slobogin Jan 1981

Capacity To Contest A Search And Seizure: The Passing Of Old Rules And Some Suggestions For New Ones, Christopher Slobogin

Vanderbilt Law School Faculty Publications

Professor Slobogin examines recent Supreme Court decisions involving standing to challenge search and seizure violations, and argues that the Court's commitment to a "totality of the circumstances" approach has permitted erosion of fourth amendment protections. After concluding that these decisions provide little guidance to lower courts, Professor Slobogin offers a set of principles which will aid in analyzing the Court's direction.
