Ex-Police Officer in Oakland Transit Shooting Freed on $3M Bail And back in the United States, the former Oakland police officer who fled California after shooting and killing an unarmed African American transit passenger has been freed on bail. The former officer, Johannes Mehserle, was caught on videotape shooting twenty-two-year-old Oscar Grant in the back while Grant 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. Mehserles $3 million bail was posted by unknown sources. BART Police Chief Gary Gee drew controversy after encouraging officers to support Mehserles bail. Mehserle was released just as several protesters were arraigned for taking part in a protest against the killing that led to more than 100 arrests.
