Lol!
Seriously. I am all about police accountability, and am not in the habit of cutting them slack.
If that’s what happened, the officer should be fired, the victim’s family should get a buttload of money, and the cop should probably face charges.
It makes much more sense (to me, anyway) than a cold blooded murder on a BART platform. Besides which, I know that cops accidentally shooting someone when they meant to tase them has been documented several times over the last 6 years.
