The cartels have been doing this for years, only Mexico's incompetence to stop it before has entire armies doing this in Mexican soil. In fact, they can't even stop them now. Not counting the corruption there(a country that needs a revolution, anarchists). If only people stopped doing drugs and giving revenue to these groups, they would be nothing. And legalization won't work here, those cartels aren't gonna give up their money. [Edited on 05.14.2012 5:43 PM PDT]
