Regardless if they were set up or not, he should not have reached into his jacket like he did. That action allowed the authorities to shoot him.
Enhanced video shows the LE on the right next to the truck, firing, and then turning away. The first hit was probably to his left side causing him to grab at it. ALL his pics show a hip holster on his right hip. Then he was shot by the LE on his right, filled by the guy on his left. This is why the LE will not explaining how many hits, and where the exit wounds are... But believe what you want. I just call it like I see it on film. Notice how some of the video screen is blocked out too.
There were a lot of things that he should not have done prior to reaching into his jacket.
He should not have driven off.
He should not told the world that he would rather die than give up.
He should not have participated in taking over the govt building.
He should not have participated in Cliven Bundy's armed confrontation.
He should not have hanging out with the Bundys.
