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 …


Policing, Databases, And Surveilance: Five Regulatory Categories, Christopher Slobogin Jan 2019

Policing, Databases, And Surveilance: Five Regulatory Categories, Christopher Slobogin

Vanderbilt Law School Faculty Publications

Databases are full of personal information that law enforcement might find useful. Government access to these databases can be divided into five categories: suspect-driven; profile-driven; event-driven; program-driven and volunteer-driven. This chapter recommends that, in addition to any restrictions imposed by the Fourth Amendment (which currently are minimal), each type of access should be subject to its own regulatory regime. Suspect-driven access should depend on justification proportionate to the intrusion. Profile-driven access should likewise abide by a proportionality principle but should also be subject to transparency, vetting, and universality restrictions. Event-driven access should be cabined by the time and place of …


Is It Time For A Universal Genetic Forensic Database?, J. W. Hazel, Ellen Wright Clayton, B. A. Malin, Christopher Slobogin Jan 2018

Is It Time For A Universal Genetic Forensic Database?, J. W. Hazel, Ellen Wright Clayton, B. A. Malin, Christopher Slobogin

Vanderbilt Law School Faculty Publications

The ethical objections to mandating forensic profiling of newborns and/or compelling every citizen or visitor to submit to a buccal swab or to spit in a cup when they have done nothing wrong are not trivial. But newborns are already subject to compulsory medical screening, and people coming from foreign countries to the United States already submit to fingerprinting. It is also worth noting that concerns about coercion or invasions of privacy did not give pause to legislatures (or, for that matter, even the European Court) when authorizing compelled DNA sampling from arrestees, who should not forfeit genetic privacy interests …


Rehnquist And Panvasive Searches, Christopher Slobogin Jan 2013

Rehnquist And Panvasive Searches, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In the history of the Supreme Court, William Rehnquist may have been the least friendly justice toward the view that the Fourth Amendment should be read expansively. Even he, however, might have interpreted the amendment to place more restrictions on modern law enforcement techniques than current caselaw does. Relying on a 1974 article authored by Rehnquist, this essay, written for a symposium on Rehnquist and the Fourth Amendment, describes his views on the types of requirements the Fourth Amendment imposes on the police, how decriminalization can protect privacy, and most importantly, why Rehnquist might have been willing to regulate surveillance …


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 …


Subpoenas And Privacy, Christopher Slobogin Jan 2005

Subpoenas And Privacy, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This symposium article, the first of two on regulation of government's efforts to obtain paper and digital records of our activities, analyzes the constitutional legitimacy of subpoenas. Whether issued by a grand jury or an administrative agency, subpoenas are extremely easy to enforce, merely requiring the government to demonstrate that the items sought pursuant to the subpoena are "relevant" to a investigation. Yet today subpoenas and pseudo-subpoenas are routinely used not only to obtain business records and the like, but also documents containing significant amounts of personal information about individuals, including medical, financial, and email records. Part I provides an …
