My God people! Are you only seeing what you want to see? He was ordered to get on the ground several times (according to Shelby) before he got to his truck. He refused, and instead kept walking to his truck. He put his hands down at the truck appearing to be either reaching into his truck or trying to open his truck; even when they ordered him not to. Shelby - an expert in recognizing someone on PCP - felt Crutcher might have been high on PCP. At this point you have to assume he is reaching for a weapon. Is that not a reasonable assumption given all the other circumstances?
Back in the day I had to take boarding team member training which included the practical pistol course multiple times. And this was in the days before body armor. I'm saying based on the training I had and our rules of engagement, until a weapon was seen, lethal force would not have been authorized.
