Incredible? Not knowing the entire story? Were only talking about trying to effectuate an arrest. He's on the floor, he resists, has no weapons on him, gets tazed, still gets up, walks around the car, opens the door and gets shot. Simple. I just don't think there was need to shoot him under those circumstances.
And I say no need to shoot him and I'm going to give you two reasons. One, as a man, how the hell can you not handle that without shooting? Even T said they should have tackled him.
Legally, there are different rules for shooting "fleeing" suspects in the back. Of course the cop is going to say he was going for the alleged knife in the car. He'll probably win on that.
My bigger issue is with use of deadly force in general. Goes to the first reason I gave above. It's too easy, in my opinion, to use "legally justified" deadly force.
