The Right To Quantitative Privacy, Danielle K. Citron, David Gray
The Right To Quantitative Privacy, Danielle K. Citron, David Gray
Faculty Scholarship
We are at the cusp of a historic shift in our conceptions of the Fourth Amendment driven by dramatic advances in surveillance technology. Governments and their private sector agents continue to invest billions of dollars in massive data-mining projects, advanced analytics, fusion centers, and aerial drones, all without serious consideration of the constitutional issues that these technologies raise. In United States v. Jones, the Supreme Court signaled an end to its silent acquiescence in this expanding surveillance state. In that case, five justices signed concurring opinions defending a revolutionary proposition: that citizens have Fourth Amendment interests in substantial quantities of …

Fighting Cyber-Crime After United States V. Jones, Danielle K. Citron, David Gray, Liz Rinehart
Faculty Scholarship
In a landmark non-decision last term, five Justices of the United States Supreme Court would have held that citizens possess a Fourth Amendment right to expect that certain quantities of information about them will remain private, even if they have no such expectations with respect to any of the information or data constituting that whole. This quantitative approach to evaluating and protecting Fourth Amendment rights is certainly novel and raises serious conceptual, doctrinal, and practical challenges. In other works, we have met these challenges by engaging in a careful analysis of this “mosaic theory” and by proposing that courts focus …
A Shattered Looking Glass: The Pitfalls And Potential Of The Mosaic Theory Of Fourth Amendment Privacy, Danielle K. Citron, David Gray
A Shattered Looking Glass: The Pitfalls And Potential Of The Mosaic Theory Of Fourth Amendment Privacy, Danielle K. Citron, David Gray
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 explores …
A Spectacular Non Sequitur: The Supreme Court's Contemporary Fourth Amendment Exclusionary Rule Jurisprudence, David C. Gray
A Spectacular Non Sequitur: The Supreme Court's Contemporary Fourth Amendment Exclusionary Rule Jurisprudence, David C. Gray
Faculty Scholarship
Much of the Supreme Court’s contemporary Fourth Amendment exclusionary rule jurisprudence is constructed upon an analytic mistake that H.L.A. Hart described in another context as a “spectacular non sequitur.” That path to irrelevance is paved by the Court’s recent insistence that the sole justification for excluding evidence seized in violation of the Fourth Amendment is the prospect of deterring law enforcement officers. This deterrence-only approach ignores or rejects more principled justifications that inspired the rule at its genesis and have sustained it through the majority of its history and development. More worrisome, however, is the conceptual insufficiency of deterrence considerations …
Neurotechnologies At The Intersection Of Criminal Procedure And Constitutional Law, Amanda C. Pustilnik
Neurotechnologies At The Intersection Of Criminal Procedure And Constitutional Law, Amanda C. Pustilnik
Faculty Scholarship
The rapid development of neurotechnologies poses novel constitutional issues for criminal law and criminal procedure. These technologies can identify directly from brain waves whether a person is familiar with a stimulus like a face or a weapon, can model blood flow in the brain to indicate whether a person is lying, and can even interfere with brain processes themselves via high-powered magnets to cause a person to be less likely to lie to an investigator. These technologies implicate the constitutional privilege against compelled, self-incriminating speech under the Fifth Amendment and the right to be free of unreasonable search and seizure …
Maryland V. King: Terry V. Ohio Redux, Tracey Maclin
Maryland V. King: Terry V. Ohio Redux, Tracey Maclin
Faculty Scholarship
In Maryland v. King, the Supreme Court addressed whether forensic testing of DNA samples taken from persons arrested for violent felonies violated the Fourth Amendment. The purpose behind DNA testing laws is obvious: collecting and analyzing DNA samples advances the capacity of law enforcement to solve both "cold cases" and future crimes when the government has evidence of the perpetrator's DNA from the crime scene.
In a 5-4 decision, the Court, in an opinion by Justice Kennedy, upheld Maryland's DNA testing statute, and presumably the similar laws of twenty-seven other states and the federal government.
Although Justice Kennedy's opinion suggests …

The Fight To Frame Privacy, Woodrow Hartzog
The Fight To Frame Privacy, Woodrow Hartzog
Faculty Scholarship
The resolution of a debate often hinges on how the problem being debated is presented. In psychology and related disciplines, this method of issue presentation is known as framing. Framing theory holds that even small changes in the presentation of an issue or event can produce significant changes of opinion. Framing has become increasingly important in discussions about privacy and security. In his new book, "Nothing to Hide: The False Tradeoff Between Privacy and Security," Daniel Solove argues that if we continue to view privacy and security as diametrically opposed to each other, privacy will always lose. Solove argues that …
