Sorry I am not buy this one and as someone who stood gate guard duty in the military, two things are wrong here, first the old Man was clearly unstable as he got out of the truck and two the officer has the benefit of his car door protecting him from the start.
My old gun training Master Chief said it best, “You better thinking and be 100% and damn sure before you pull that trigger because, you can’t recall bullets once their are fired!”
Hear, Hear !
