In Oakland, a BART transit officer has been captured on videotape pulling a drunk man off a train and then slamming his head into a large window, shattering the glass. After his head was slammed into the window, Michael Joseph Gibson was charged with resisting arrest, assaulting an officer and public intoxication. An attorney for Gibson said he plans to sue the BART transit agency over the incident. According to his family, Gibson has been diagnosed with bipolar disorder. Earlier this year, a BART police officer was caught on videotape fatally shooting an unarmed African American man named Oscar Grant on a train platform on New Year’s Day.
