Visualizing Dna Proof, Nicholas L. Georgakopoulos

Nicholas L Georgakopoulos

DNA proof inherently involves the use of probability theory, which is often counterintuitive. Visual depictions of probability theory, however, can clarify the analysis and make it tractable. A DNA hit from a large database is a notoriously difficult probabi­li­ty theory issue, yet the visuals should enable courts and juries to handle it. The Puckett facts are an example of a general approach: A search in a large DNA database produces a hit for a cold crime from 1972 San Francisco. Probability theory allows us to process the probabilities that someone else in the database, someone not in the database, or …

Dna Storage Banks: The Importance Of Preserving Dna Evidence To Allow For Transparency And The Preservation Of Justice, Cristina Martin

Chicago-Kent Law Review

What is the duty to preserve information in today’s society? In order for humanity to evolve, change and flourish in the future, society needs to preserve its information from the past. In the criminal justice field, preservation of evidence has special significance. DNA evidence in particular has become a helpful aid for innocent defendants who have been improperly imprisoned. Over the past twenty years, the number of exonerations of imprisoned criminal defendants has increased dramatically. With the advancement of technology, old, previously untestable or improperly tested DNA evidence will need to be retested. However, most states do not have proper …

Statistics In The Jury Box: How Jurors Respond To Mitochondrial Dna Match Probabilities, David H. Kaye, Valerie P. Hans, B. Michael Dann, Erin J. Farley, Stephanie Albertson

Valerie P. Hans

This article describes parts of an unusually realistic experiment on the comprehension of expert testimony on mitochondrial DNA (mtDNA) sequencing in a criminal trial for robbery. Specifically, we examine how jurors who responded to summonses for jury duty evaluated portions of videotaped testimony involving probabilities and statistics. Although some jurors showed susceptibility to classic fallacies in interpreting conditional probabilities, the jurors as a whole were not overwhelmed by a 99.98% exclusion probability that the prosecution presented. Cognitive errors favoring the defense were more prevalent than ones favoring the prosecution. These findings lend scant support to the legal argument that mtDNA …

Calling Out Maryland V. King: Dna, Cell Phones, And The Fourth Amendment, Jennie Vee Silk

Jennie Vee Silk

In Maryland v. King, the Supreme Court narrowly upheld a Maryland statute that permits police to obtain a DNA sample from an arrestee without a search warrant. A year later, the Court drastically changed course and provided significantly more protection to an arrestee’s privacy. In a unanimous decision, the Court in Riley v. California held that police must obtain a search warrant before they can search the cell phone of an arrestee.

This article is the first to compare the Court’s conflicting decisions in Riley and King. Riley and King present the same issue: governmental invasion of privacy for …

Forensic Evidence And The Court Of Appeal For England And Wales, Lissa Griffin

Elisabeth Haub School of Law Faculty Publications

The Criminal Division of the Court of Appeal has extensively analyzed the role of forensic evidence. In doing so, the court has grappled with the admissibility and reliability of a broad range of forensic evidence, from DNA and computer forensics to medical and psychological proof, to more outlying subjects like facial mapping, fiber analysis, or voice identification. The court has analyzed these subjects from two perspectives: the admissibility of such evidence in the lower courts and the admissibility of such evidence as fresh evidence on appeal. In both contexts, the court has taken a practical approach to admitting forensic proof …
