How far do you think he trotted off after the shot? Could be wrong but seemed like 50/60 yards? Would you have taken a shot at him again? I sure the hell wouldn't have sat there and laughed while filming him. Get the hell out of the tree and stalk him or something.
He may as well have posted a video of him cutting his dog's tail off with a pair of tin snips. I'd think no more or less of him.
Assuming that was no accident...thats the type of "hunter" that needs to have an accident himself. That crap pisses me off! Unfortunately, there's many more of these idiots out there.
