Well it did in fact end up lethal. However that was up to the guy that pulled the trigger. However the way I read the law as quoted in the one comment such lethal force is only justified if a reasonable person would judge there was a "substantial risk of death or serious bodily harm". Since the big guy obviously wanted to keep trespassing on the lawn until the verbal dispute was settled to his satisfaction, and since the big guy gave no indication of wanting to harm the small guy or anybody else. It is absurd to think that him trying to take the gun away was likely to be a prelude to a deadly attack. Seems 99.999% likely he just adamantly did not want to leave yet and did not want to be shot either.
Well, he didn’t leave. And he was shot. So he got one half of his wish. Suqs to be him.
I do agree with the assessment that the big dude was calling a bluff. It wasn’t a bluff.
It’s interesting to see what would be a bad shoot in one state is not even filed in another.
