He was pulling up his pants. Why would he decide to pull out a gun as he’s being faced down by 2 officers with rifles? Why would he comply with their endless stupid demands if he intended to pull out a gun? If he intended to shoot, why not do it before surrendering? Those cops got on the scene intending to kill someone. They shouted confusing demands at him, hoping for him to slip up; as if to justify their cold-blooded murder. If they intended to arrest him, they would’ve done so the second he surrendered himself, but they wanted to play with their prey. Whether or not the cops genuinely believed he was reaching for a gun is immaterial, because everything else surrounding the case shows that they’re totally unfit for the position.
