BART announced this afternoon that they finished up their internal investigation into the shooting death of Oscar Grant on New Year's Day. The results haven't been made public, but they were handed over at the Alameda County District Attorney's Office, who will decide whether or not they want to press charges against Johannes Mehserle. The folks over at Bay Area Rapid Transit, if you recall, initially took their sweet time in investigating the shooting. Community folks have been incensed over Grant's death, which resulted in protests and a small riot. A San Francisco protest is planned for later this afternoon.
