America's crime rate is also tied to lots of gang/cartel/syndicate type groups which either (a) follow the money, (b) just walk across the gigantic undefended border, and/or (c) developed as a massive side-effect of segregation and swallowed up whole communities in cyclical violence. And (d) not so much anymore, but prohibition and the widespread cultural glamorization of the bootleggers and smugglers who fed us booze is probably still having some impact on the crime landscape, even though that was a while back. But you can certainly draw parallels to modern drug policies.
