In what's beginning to look like an unfortunate accident, BART officer Johannes Mehserle resigned today after fatally shooting Oscar Grant at the Frutivale BART station on New Year's Day. Johannes Mehserle was supposed to meet with BART police investigators today, but at the meeting, which Mehserle didn't attend, the officer's attorney and his union representative turned in his resignation letter. The BART Police investigation, though, will "continue to seek and examine all available evidence and will continue its full cooperation with the ongoing independent investigation by the District Attorney," according to Really, this is a tragedy for everybody involved. We feel for both parties.
