And in California, the police officer involved in a New Year’s Day shooting of an unarmed transit passenger has resigned. Officer Johannes Mehserle stepped down just before he was set to be interviewed by investigators. Cell phone videos show Officer Mehserle pulling out a gun and shooting twenty-two-year-old Oscar Grant in the back while he was lying face down on the ground on a subway platform. Grant worked as a butcher at an Oakland grocery store and was the father of a four-year-old daughter. He was buried on Wednesday. Fifteen people were arrested in Oakland Wednesday night after hundreds turned out to protest Grant’s killing.
