Listen to James Doyle discuss the basics of a "sentinel event" review in the criminal justice system. This learning-from-error approach borrows from principles that medicine, aviation and other high-risk enterprises have successfully used. Former NIJ Fellow Doyle offers the basics to understand this innovative idea that takes a system-wide perspective of error, bringing all stakeholders together in a non-blaming, forward-looking way after a bad outcome, such as a wrongful conviction, occurs.

The 2009 NIJ Conference kicked off with a blue-ribbon panel of leaders with expertise in urban issues as they relate to homicide. These experts will discuss promising approaches that have resulted in reduced violence and community empowerment.

Evidence backlogs have been known to be an issue in crime laboratories. A recent study published by NIJ has shown that backlogs of untested evidence are also an issue in law enforcement evidence storage. This panel will discuss the issues and present preliminary findings from a study of the Los Angeles Police Department's and Los Angeles County Sheriff's Department's experience with clearing out a large backlog of unanalyzed rape kits.

Forensic examinations involving specific forensic science disciplines are typically dependent upon qualitative analyses and expert interpretation of observed patterns based on a scientific foundation, rather than quantitative results. These disciplines include latent fingerprints, questioned documents, footwear, and other forms of impression and pattern evidence.
