A Shattered Looking Glass: The Pitfalls And Potential Of The Mosaic Theory Of Fourth Amendment Privacy, David C. Gray, Danielle Keats Citron Jan 2013

A Shattered Looking Glass: The Pitfalls And Potential Of The Mosaic Theory Of Fourth Amendment Privacy, David C. Gray, Danielle Keats Citron

Faculty Scholarship

On January 23, 2012, the Supreme Court issued a landmark non-decision in United States v. Jones. In that case, officers used a GPS-enabled device to track a suspect’s public movements for four weeks, amassing a considerable amount of data in the process. Although ultimately resolved on narrow grounds, five Justices joined concurring opinions in Jones expressing sympathy for some version of the “mosaic theory” of Fourth Amendment privacy. This theory holds that we maintain reasonable expectations of privacy in certain quantities of information even if we do not have such expectations in the constituent parts. This Article examines and …


A Fourth Amendment Theory For Arrestee Dna And Other Biometric Databases, David H. Kaye Jan 2013

A Fourth Amendment Theory For Arrestee Dna And Other Biometric Databases, David H. Kaye

Journal Articles

Routine DNA sampling following a custodial arrest process is now the norm in many jurisdictions, but is it consistent with the Fourth Amendment? The few courts that have addressed the question have disagreed on the answer, but all of them seem to agree on two points: (1) the reasonableness of the practice turns on a direct form of balancing of individual and governmental interests; and (2) individuals who are convicted — and even those who are merely arrested — have a greatly diminished expectation of privacy in their identities.

Publications

The First Amendment protects anonymous speech, but the scope of that protection has been the subject of much debate. This Article adds to the discussion of anonymous speech by examining anti-mask statutes and cases as an analogue for the regulation of anonymous speech online. Anti-mask case law answers a number of questions left open by the Supreme Court. It shows that courts have used the First Amendment to protect anonymity beyond core political speech, when mask-wearing is expressive conduct or shows a nexus with free expression. This Article explores what the anti-mask cases teach us about anonymity online, including proposed …


An Ethical Duty To Protect One’S Own Information Privacy?, Anita L. Allen Jan 2013

An Ethical Duty To Protect One’S Own Information Privacy?, Anita L. Allen

All Faculty Scholarship

People freely disclose vast quantities of personal and personally identifiable information. The central question of this Meador Lecture in Morality is whether they have a moral (or ethical) obligation (or duty) to withhold information about themselves or otherwise to protect information about themselves from disclosure. Moreover, could protecting one’s own information privacy be called for by important moral virtues, as well as obligations or duties? Safeguarding others’ privacy is widely understood to be a responsibility of government, business, and individuals. The “virtue” of fairness and the “duty” or “obligation” of respect for persons arguably ground other-regarding responsibilities of confidentiality and …
