For more than 40 years, the U.S. government has waged a war on drugs. Millions have been put in prisons, billions spent on enforcement, and yet the price of drugs on the street has only gone down, and the quality has gotten better. In Mexico, roughly 60,000 people have died in drug-related violence from 2007-2012, and, despite reforms, violence persists today. Drug kingpins have moved from just trading drugs, to activities like taxing businesses, and running human trafficking networks. They control some towns in the Mexican heartland and also along the border, but in some regions locals have formed self-defense groups to fight back.
