It's an interesting though, that it's possible (no idea how likely) that violence could be decreased through a reduction in laws such that the amount of enforcement -- and thus violence -- is reduced.
I really wish that we had good stats on this stuff so that the laws could be crafted to minimize violence. Anyone who says we're civilized and "beyond that" isn't paying attention, it's just that the violence has largely been outsourced so that a portion of affluent society can feel that we're "beyond that".

Gang members seem to have no regard for enforcement of any kind and throw their lives away with abandon, but I still think less enforcement will only embolden them.
There's a school of thought that we inadvertently create terrorists by interfering in the middle east and thus motivating people to want to do us harm. And by 'we' I mean 'The United States'.
I suspect that a similar argument can be made that the illegal drug trade and gangs are fairly well correlated and that gangs arise because individuals don't derive any security from the police for a variety of reasons. So gangs are the result of police policy, not that police policy is the result of gangs.
I'm not suggesting that this is a 100% solid theory. But there's probably some nugget of truth in it.
Gangs tend to organize around any kind of illegal, lucrative market. Smuggling (which is really what drugs and alcohol are about), gambling, prostitution, vote buying/selling, theft. Because those activities are outside the law, the law can't really regulate the market.
Then there is racketeering/blackmail, which is probably more of a problem of ineffective policing, at least as far as the "Hey, you've got a nice business here, how about you give me a cut to make sure nobody comes by [sic buy] and smashes your cabbages" variety goes.
I detected a hint of "the cop is the perp and the perp is the victim" in your other post but wanted to give you the benefit of the doubt. This kind of attitude is quickly disabused of when living in a poor neighborhood. Why are gang members practically suicidal? Drugs play a part, but they are not protecting their neighborhood they are trying to get a larger territory to deal drugs. As for the US going into the Middle East, it was probably a bad idea but then people turn around and complain we are not doing anything in Syria.
