As the Mehserle defense rests its case today, former San Francisco Police Chief Frank Jordan told SF Weekly that he's not buying Mehserle's story. "My personal opinion is, [Mehserle's story] is pretty hard to believe," Jordan tells the Weekly. "I don't see myself ever pulling out a handgun when I wanted to use a Taser. The handgun is absolute last resort. The Taser is supposed to minimize the situation so you don't kill somebody. It's an interesting alibi and I'm not sure it's one I buy into." While he doesn't think Mehserle killed Oscar Grant in cold blood -- no one suspects that's the case, save a few aggressively earnest first-year Cal students -- the former Chief presumes the infamous BART cop "was under emotional stress" and panicked.
