> That legalizing drugs would make the cartels and the violence disappear. I wonder, however, if drugs had never become illegal would a major crime organization managed to form in the first place?
Russia has major crime organizations without having a reputation as a narco place.
Mexican cartels have the infrastructure already in place: "Miguel, get 25 guys and hijack the fuel trucks"...or rob armored trucks. That infrastructure, including manpower, political protection etc was built and is probably maintained with drug money.
