Post Mortem: Death Investigation in America

Frontline correspondent Lowell Bergman discusses "Post Mortem," a collaborative investigation by Frontline, ProPublica, and NPR that discovered a dysfunctional autopsy system with few standards and little oversight. Errors by coroners and forensic pathologists have allowed potentially guilty perpetrators to go free and the innocent to be accused of crimes they didn’t commit. "Post Mortem" airs February 1, on PBS at 9 pm.
