Ok then. USA only. Clubs and chapters ebb and flow in criminality. Things go up and down over the last 70 years. There is no single answer. Many of them absolutely fear prison. As for violence--the mob can order guys to wack people.

Can bikers? Not usually. You're talking about cold blooded premeditated murder. The majority of guys simply won't do that. Remember a killing and cold blooded murder are not necessarily the same. We're talking about a hit. Have bikers done it? Absolutely. But to apply that across the board would be wildly inaccurate. Is the average 1% bike club member capable of killing someone in a fight? Fuck yeah. So are a lot of the riders who aren't even in 1% clubs.

You've got to remember that law enforcement has unlimited money and power to throw at these guys. They can only get so far out of control before it all comes crashing down. The 90's Outlaws are a well known example of that. And remember that was the old days when everything was still underground. That level will never be reached and maintained again.

The rackets: there are a few, mostly old examples of clubs getting involved in this stuff, but mafia for the win. Not even close.

Fact is, it's damn expensive to own a Harley and ride all over. A lot of guys can do it easier working a straight job than being a criminal. If you've never ridden a Harley, let me tell you, you're on this big loud motherfucker, you're exposed to the elements, dirty, wet maybe, every cocksucker in a car is driving like they get a million dollar reward if they murder you with their vehicle, cops will fuck with ya for no reason, assholes want to test you, usually 3 or 4 on 1, that's where the whole attitude comes from for the majority. Not because they will do hits, carry kilos of blow around or do all this other crazy shit.
