But there it is -
He wasn't killed for a cigarette. Cops make initial contact because of a legit call and he died because he was not cooperating at all. He completely resisted them.
As GFGT said - it wasn't worth dying for. Well, maybe for him it was cause he went for it.
Did they? Where's proof of that? Did the officers view the crime, or was it called in? If it was called in, under what authority do they have to physically restrain him?
