Here's video of police shouting "burn that motherfucker" and "burn him out" as Dorner was trapped.

172. OK, I thought this through a little

and I get the fear thing. The incompetence is there regardless of whether they went out to kill him or not, the wrongly identified vehicles that they shot up at least prove that. And their fear probably was at least part of why they went ballistic. I don't know whether the officers involved jumped the gun, or if there was a mission directive to kill (I hope we eventually find outm or if someone knows, post it here). If I think there was revenge or bloodlust contributing to the lethal force (and I do), that's a supposition on my part, though the video in the OP might back up that line of thinking.

Even if it had been him in those vehicles, they should have had to do due diligence not only to verify it was him, but also that their only choice was to kill him. It doesn't look to me like they did that.
