Police tasings, which have provided endless entertainment over the last few years, are commonplace for itchy triggerfingered cops. According to SFGate, that's just what Bart cop Johannes Mehserle wanted to do in lieu fatally shooting and killing Oscar Grant on New Year's Day.

In court today, Attorney Michael Rains "wrote in a court document that a second BART officer, Tony Pirone, reported hearing Mehserle say just before shooting Oscar Grant, 'I'm going to tase him, I'm going to tase him.'" Did Mehserle mistake his pistol for his taser? We can't say just yet, but this sounds like it could be Mehserle defense.

The Gate goes on to say that Mehserle was described as 'looking stunned after he shot Grant ... [and that 'had an expression on his face like, 'Holy s-, what happened or what did I do, with his hands around his head.'" (At least so say the defense attorney.) Which is to say, it's a safe bet that Mehserle did not intend to kill Grant and that he felt remorse after doing so, hence a tragedy for everyone involved.

Conspiracy theorists, feel free to vent in the comments.

Johannes Mehserle was arrested in Nevada today in connection with the shooting and killing of Oscar Grant on New Year's Day. According the Chronicle, "Mehserle, 27, was taken into custody in Douglas County, Nevada, said Deputy Steve Velez of the Douglas County Sheriff's Office. The arrest was also confirmed by David Chai, chief of staff to Oakland Mayor Ron Dellums." (Due to death threats, Mehserle stashed himself in Nevada.) It seems an Alameda County judge signed an arrest warrant today, and Mehserle surrendered with no fuss or muss. A surprising update to this case for sure. We will update with more when more details of the arrest are made public on Wednesday.

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 BART.gov. Really, this is a tragedy for everybody involved. We feel for both parties.
