I watched the video may times. He crashes his car in the snow (almost plowing through the roadblock). The he immediately jumps out of the car and runs towards the officers (yes with his hands up). Then he reaches for his gun twice in order to provoke the police to shoot him. I don't know it was right for the police to shoot him, although it was definitely his intention to die there (read what he said beforehand also). The police were most likely legally justified in killing him since he charged at them after nearly crashing his car. Although, you can see the officer in the woods was the one who shot him from behind (this officer did not have a clear view if he actually grabbed his gun or not). The officers with the front view could see he did not actually grab his gun, he just gestured for it, and did not shoot him. This is fully suicide by cop, this guy wanted to be a martyr and had a deathwish which was granted.
If he really wanted to surrender, could have put his hands up through his window. Basically, LeVoy is playing 100% people like you, "liberty" folk who seem to think occupying a federal building is the new Boston Tea Party, and you are eating up the bait pretty deliciously.
