Shooter was def well trained, to fire from a vehicle out the window and hit his intended target is a skill not often learned. But stupidness all around. Like the guy who stops the innocent driving bystander (that makes the video feed from the alt view). That idiot has no right to stop traffic. Then shooter gets into the block and this traffic blocker and all the ptotesters run towards the shooters car like a mob. Then suprise when shots ring out. The dead guy knew why he was open packing, same as anyone that does so in public. To put everyone on motice that they mean business and intimidation. Its stupid to do it because if shit escalates you leave yourself only 1 option. The sling the dead guy wore is not made to shoulder the weapon but to keep it at all times in the low ready position. A positition meant so you can quickly get into shooting mode. My opinion is it looks like some of the protesters like dead guy were security for the group, you can see a few guys in black knee pads and vests out front appear to be carrying (maybe, not sure). They look like they are providing half ass security. Shit hit the fan with the car and they all charged towards the car looking to handle the situation. Shooter sees low ready rifle from his seated position and it could look like barrel is pointed at him (which it very well could have been). Shooter shoots, game over. Shooter is prolly fucked with the Travis Co DAs office no matter what APD does. I get they want to protest, but why so late in the dark?? Just a recipe for disaster.
