Clear case of intimidation and murder by a massive force of LEO, looks like a shot in the back after the first hit, hands up.
Then the truck was shot up vigorously.
They wanted a victim and to make an example to scare the group very badly. Buffalo gap indeed.
If that's true, there's audio, too.
Look at 13:20 and on. There’s a laser scope being trained on LaVoy, mostly on his head. Where is it coming from? I remember reading that there was a sniper in a tree. Do they think he might be a threat at that point?
