Without a lot of people being very restrained, and trying to be polite, this person is still alive.

But, as you said, it has gone to far.
He should be found, outside, down the stairs with a bloody nose, and the police should show up and ask, "Did you learn your lesson?"
Instead, the good person who had their privacy and space invaded, may go to jail.

Good thing for him he doesn't do this in the bayou, or some holler.
Then it would be... well, he just never uploaded another video again...
