They both were foolish. He had no right to tell her to stop smoking. No a big deal, but it was foolish and unnecessary. But the woman was a goddamn fool. You just don't pop off to a cop and resist arrest when you don't have enough money to bail yourself out. That's Sassy Bitch 101. How stupid can you get? He fouled up again she he pulled the taser on her. She wasn't threatening him and she was endangering nobody, she was just acting out. He should have called for backup and got the whole team there including the female officer that goth there within a few minutes anyway. Bland was clearly not going to cooperate, she was going to jail. So why take on the whole potential hassle by yourself. That's Asshole Cop 101. In any case he's not responsible for her suicide. Since she had tried to commit suicide before and nobody had any incentive to kill her and there is no evidence to the contrary . . . it was suicide.
Marijuana is a non-issue. She wasn't holding, so it's nothing. Weed does not cause suicide. It actually makes your problems easier to deal with. If the cop had been stoned, this probably never would have happened. What do you imagine that the mug-shot proves? It's a mug shot. Watch the video of the mugshot. She is awfully animated for a corpse. http://abc13.com/news/new-video--released-in-sandra-bland-case/888802/
