A white former transit officer in Oakland, Calif., has been charged with murder in the shooting death of an unarmed black man. Johannes Mehserle was arrested two days ago in Nevada. He’s charged with shooting Oscar Grant as he was lying face down on a train platform in Oakland. The shooting sparked a series of violent street protests. It also has heated up long-standing tension between law enforcement authorities and African-American residents. The shooting of Grant was captured on cell phone video which really outraged the community because it shows the victim already on the ground when officer Mehserle pulls the trigger killing the man!
