Are you surprised that nobody ever tried to be like the Saints?

With all the cities and all the millions of people who live in them in America, are you surprised that nobody ever decided to attempt to avenge the public by going out and killing criminals on a regular basis until they are caught? I am a bit surprised it never happen, it would be much harder to take on mob bosses and things like that, but common street criminals could be done. Especially now with social media I am surprised that nobody ever started it just to instantly become the most popular guy in America for a bit. Yes, I know in the start to Kick Ass they ask the question of why nobody ever tried to be a super-hero, and explain why that's impossible, but this is different and could conceivably happen.
