Again, it doesn't matter if he was insulting their mom. The responsibility for the physical attack rest solely on the "gentle giant man of God".
I imagine, the rest of the video will show the barking trooper starting out in a more reasoned manner and then growing more forceful as the two drunkards start launching colorful metaphors and refuse to get out of the ditch. Even then, he didn't initiate the assault or get physical. This wasn't a one sided conversation...you just hear more of the trooper's audio due to his proximity to the mic.
So why not show it, and vindicate the whole mess?
