Like legalizing marijuana. It would stop a major revenue source for the Mexican drug businesses and keep our drug dollars at home where they can be taxed.
Oh, puleeze. Legalizing marijuana will do NOTHING to stop these criminals. They'll just continue on to the next profitable outlawed business that the idiots in the US will buy into. Marijuana is at the bottom of their food chain. Take off that link and their are plenty more to exploit.
You are correct:
John P. Walters, director of the Office of National Drug Control Policy, said marijuana, not heroin or cocaine, is the "bread and butter," "the center of gravity" for Mexican drug cartels that every year smuggle tons of it through the porous U.S.-Mexico border. Of the $13.8 billion that Americans contributed to Mexican drug traffickers in 2004-05, about 62 percent, or $8.6 billion, comes from marijuana consumption.
