No I definitely saw a G4 special several years ago, and I think that Dark Guardian was featured on it. He is supposedly well-trained in martial arts. In the special he was harrasing some drug dealer, saying "I know what you're doing, get the hell out of the park before i kick your ass". I just thought it'd be hilarious if the drug dealer suddenly pulled out a g-18 from his pants and wasted him with 10 or 15 rounds.
These people are wrong, doing what they do. It's the same as someone walking up to you and demanding your money. Just because they're doing it to specific people and doing it for a different reason doesn't mean the end result is the same: random tough guys stalking the streets , trying to intimidate other people for the feeling it gives them.
There are laws against this kind of shit, because it's detrimental to our individual freedom. There is nothing stopping these people from dishing out beatings,perhaps maiming or killing people, at their own whim. There is no investigation, no proof, no nothing; only people who have decided they're capable of discerning who it's okay to harass and beat up, simply and literally because they feel like it
