A Cognitive Theory Of The Third-Party Doctrine And Digital Papers, H. Brian Holland

Faculty Scholarship

For nearly 200 years, an individual’s personal papers enjoyed near-absolute protection from government search and seizure. That is no longer the case. With the widespread adoption of cloud-based information processing and storage services, the third-party doctrine operates to effectively strip our digital papers of meaningful Fourth Amendment protections.

This Article presents a new approach to reconciling current third-party doctrine with the technological realities of modern personal information processing. Our most sensitive data is now processed and stored on cloud computing systems owned and operated by third parties. Although we may consider these services to be private and generally secure, the …

Constitutional Shapeshifting: Giving The Fourth Amendment Substance In The Technology Driven World Of Criminal Investigation, Gerald S. Reamey

Faculty Articles

For the first hundred years of the Fourth Amendment's life, gains in the technology of surveillance were modest. With the advent of miniaturization and ever-increasing sophistication and capability of surveillance and detection devices, the Supreme Court has struggled to adapt its understanding of "search" to the constantly evolving devices and methods that challenge contemporary understanding of privacy. In response to surveillance innovations, the Court has taken varying positions, focusing first on property-based intrusions by government, then shifting to privacy expectations, and, more recently, resurrecting the view that a trespass to property can define search.

This article surveys this constitutional odyssey, …

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 …

Unlocking The Fifth Amendment: Passwords And Encrypted Devices, Laurent Sacharoff

Sturm College of Law: Faculty Scholarship

Each year, law enforcement seizes thousands of electronic devices — smartphones, laptops, and notebooks — that it cannot open without the suspect’s password. Without this password, the information on the device sits completely scrambled behind a wall of encryption. Sometimes agents will be able to obtain the information by hacking, discovering copies of data on the cloud, or obtaining the password voluntarily from the suspects themselves. But when they cannot, may the government compel suspects to disclose or enter their password?

This Article considers the Fifth Amendment protection against compelled disclosures of passwords — a question that has split and …

Terry Stops And Frisks: The Troubling Use Of Common Sense In A World Of Empirical Data, David A. Harris, David Rudovsky

Articles

The investigative detention doctrine first announced in Terry v. Ohio and amplified over the past fifty years has been much analyzed, praised, and criticized from a number of perspectives. Significantly, however, over this time period commentators have only occasionally questioned the Supreme Court’s “common sense” judgments regarding the factors sufficient to establish reasonable suspicion for stops and frisks. For years, the Court has provided no empirical basis for its judgments, due in large part to the lack of reliable data. Now, with the emergence of comprehensive data on these police practices, much can be learned about the predictive power of …

Game Of Drones: Rolling The Dice With Unmanned Aerial Vehicles And Privacy, Rebecca L. Scharf

Scholarly Works

This Article offers a practical three-part test for courts and law enforcement to utilize when faced with drone and privacy issues. Specifically addressing the question: how should courts analyze the Fourth Amendment’s protection against ‘unreasonable searches’ in the context of drones?

The Supreme Court’s Fourth Amendment jurisprudence produced an intricate framework to address issues arising out of the intersection of technology and privacy interests. In prominent decisions, including United States v. Katz, California v. Ciraolo, Kyllo v. United States, and most notably, United States v. Jones, the Court focused on whether the use of a single …
