What’s Possible with Rapid DNA Technology?
NIJ scientist Tracey Johnson joins science writer Sarah Michaud in this episode. They discuss Rapid DNA technology, and Tracey explains the complexities of this technology – its pitfalls and its possibilities.

Legitimacy and Community Cooperation With Law Enforcement
Tom R. Tyler, chair of the New York University psychology department, describes research on profiling and community policing. His research found that citizens of all races show greater respect for law enforcement when they believe officers are treating them fairly. Even citizens who experienced a negative outcome getting a traffic ticket, for example showed higher levels of respect for and cooperation with law enforcement as long as they believed they were not being singled out unfairly.
Sexual Assault: Obtaining DNA From Evidence Collected up to a Week Later
Technological advances have made it possible to detect male DNA in evidentiary samples collected several days after a sexual act has taken place. Panelists will present the research that has led to these findings, followed by a discussion of the potential impact of this work from the perspectives of the sexual assault nurse examiner (SANE) and the crime laboratory communities.
Familial DNA Searching: Issues and Answers
Familial DNA searching is the practice of creating new investigative leads in cases where DNA evidence found at the scene of a crime strongly resembles that of an existing DNA profile but is not an exact match. Panelists will explain how the technology works, provide examples of successful convictions obtained through familial searches, and discuss the various misconceptions and concerns regarding this practice.
