It's What Happens When Gil Grissom Leaves CSI

After a two-year review, the National Academy of Sciences is set to release a report this month on the state of forensic science in the US -- and it's not looking good. The New York Times says people call the report a "sweeping critique of many forensic methods that the police and prosecutors rely on." Those methods include the analysis of bite marks, blood spatter, hair, and handwriting as well as fingerprinting and firearms identifications. According to the Times, the report says the analyses are carried out by "poorly trained technicians who then exaggerate the accuracy of their methods in court." It then suggests that Congress establish a federal agency that keeps forensics separate from law enforcement agencies.
