Ok, so Mexico bans ALL GUNS. Yet the cartels have all manner of automatic weapons. Granted, Operation Gun Runner is responsible for many of weapons being there, the truth is the ban in Mexico has not worked at all. Beginning in 1920, the US banned ALL ALCOHOL, yet criminals had all the alcohol you could want. For the last 4 decades we have made possession of marijuana, cocaine, heroin, meth etc. Whataya know? It is almost as easy to get any of those as it is to get a six pack of beer. Tell me one time that a ban has succeeded in curing the perceived evil and also had no serious unintended consequences? The American mafia only because the power it is now through prohibition. Before that they were a small time numbers and protection racket. The mexican cartels are wealthy because we make drugs illegal. Bans fail, they always have and always will.
