Self Incrimination And Cryptographic Keys, Gregory S. Sergienko

Greg Sergienko

Modern cryptography can make it virtually impossible to decipher documents without the cryptographic key thus making the availability of the contents of those documents depend on the availability of the key. This article examines the Fourth and Fifth Amendments' protection against the compulsory production of the key and the scope of the Fifth Amendment immunity against compelled production. After analyzing these questions using prevailing Fourth and Fifth Amendment jurisprudence, I shall describe the advantages of a privacy-based approach in practical and constitutional terms.

On The 'Considered Analysis' Of Collecting Dna Before Conviction, David H. Kaye

David Kaye

For nearly a decade, DNA-on-arrest laws eluded scrutiny in the courts. For another five years, they withstood a gathering storm of constitutional challenges. In Maryland v. King, however, Maryland's highest court reasoned that usually fingerprints provide everything police need to establish the true identity of an individual before trial and that the state's interest in finding the perpetrators of crimes by trawling databases of DNA profiles is too "generalized" to support "a warrantless, suspicionless search." The U.S. Supreme Court reacted forcefully. Chief Justice Roberts stayed the Maryland judgment, writing that "given the considered analysis of courts on the other side …

Maryland V. King: Per Se Unreasonableness, The Golden Rule, And The Future Of Dna Databases, David H. Kaye

David Kaye

In Maryland v. King, the Supreme Court applied a balancing test to uphold a Maryland statute mandating preconviction collection and analysis of DNA from individuals charged with certain crimes. The DNA profiles are limited to an inherited set of DNA sequences that are not known to be functional and that are tokens of individual identity. This invited online essay examines two aspects of an article on the case by Professor Erin Murphy. I question the claim that the case is pivotal in a conceivable abandonment of the per se rule that warrantless, suspicionless searches are unconstitutional unless they fall …

Dna Typing: Emerging Or Neglected Issues, David H. Kaye, Edward J. Imwinkelried

David Kaye

DNA typing has had a major impact on the criminal justice system. There are hundreds of opinions and thousands of cases dealing with DNA evidence. Yet, at virtually every stage of the process, there are important issues that are just emerging or that have been neglected.At the investigative stage, courts have barely begun to focus on the legal limitations on the power of the police to obtain samples directly from suspects and to use the data from DNA samples in various ways. Issues such as the propriety of "DNA dragnets" (in which large numbers of individuals in a geographic area …

Dna Identification Databases: Legality, Legitimacy, And The Case For Population-Wide Coverage, David H. Kaye, Michael E. Smith

David Kaye

Over the past decade, law enforcement authorities have amassed huge collections of DNA samples and the identifying profiles derived from them. Large DNA databanks routinely help to identify the guilty and to exonerate the innocent, but as the databanks grow, so do fears about civil liberties. Perhaps the most controversial policy issue in the creation of these databases is the question of coverage: Whose DNA profiles should be stored in them? The possibilities extend from convicted violent sex offenders to all convicted felons, to everyone arrested, to the entire population. This Article questions the rationales for drawing the line at …

The Piranha Is As Deadly As The Shark: A Case For The Limitation On Deceptive Practices In Dna Collection, Brett A. Bauman

Brett A Bauman

Police deception tactics are utilized throughout the United States as a way to catch unsuspecting criminals. Although criticized in many respects, most deceptive police techniques are not only legal, but are actually encouraged. DNA collection and analysis is no exception—techniques are frequently used by law enforcement officers in an attempt to collect a suspect’s genetic specimen in the interest of solving crimes. While law enforcement officers typically have the best interests of society in mind, the current practices employed by officers to collect suspects’ DNA violate the Fourth Amendment. The Fourth Amendment provides protection against unreasonable searches and seizures, and …

Full Disclosure: Cognitive Science, Informants, and Search Warrant Scrutiny

By Mary Nicol Bowman

This article posits that cognitive biases play a significant role in the gap between the rhetoric regarding Fourth Amendment protection and actual practices regarding search warrant scrutiny, particularly for search warrants based on informants’ tips. Specifically, this article examines the ways in which implicit bias, tunnel vision, priming, and hindsight bias can affect search warrants. These biases can affect each stage of the search warrant process, including targeting decisions, the drafting process, the magistrate’s decision whether to grant the warrant, and post-search review by trial and appellate …
