BART's shooting probe missteps
BART's investigation into a police officer's fatal shooting of an unarmed rider was plagued with problems from the start, a Chronicle investigation has found.
Johannes Mehserle is charged with murder.
BART police allowed a train full of witnesses to pull out of the Fruitvale Station in Oakland early New Year's Day after Officer Johannes Mehserle shot Oscar Grant, then made little effort to contact the witnesses as they got off at other stations.
