Crime Lab DNA Databases Under the Microscope

April 7, 2010

Researchers in the field of DNA forensics are calling for the FBI to improve the quality of its sizable genetic database by letting them look under the hood. As Osagie Obasogie explains, reviews of a handful of state crime lab DNA databases have revealed anomalies that might not make prosecutors’ claims that a crime-scene sample matching a profile in the database is “slam dunk” evidence. Genetic information is a powerful law enforcement tool—both for catching criminals and for exonerating the innocent, but both uses require robust, accurate science. (Science Progress)
