While I agree the YouTube kid kind of got what was coming to him, the shooter isn’t a straight up hero.
As annoying as this kid was it doesn’t sound like he ever touched the guy. I would completely understand the shooter shoving, punching, or even using mace/taser on the YouTube guy, but jumping straight to shooting someone over that is just a bit unhinged behavior, at least in my opinion.
I am not against CCW or self defense or anything, but the shooter definitely went overboard, and I wouldn’t be surprised if he is found guilty in the court case.
