How about this for illegal.
The US Government created, and maintains an illegal Market, in Mexico, so that they can invest in an unregulated Market, that they can control entirely.
Caldereon, though on board, has even publicly asked from the US Government to end the War on Drugs, as he can not deal with over 100 dead bodies every month, as Joaquin Guzman and others up their worth to over $100 Billon over the next 5 years.
Mexico IS basically the USA, and these Para-Military Drug Cartels are about as far South of Colorado, as Ohio is to the East.
Your Government, it would appear, is more loyal to the dollar, than it is their people, as they continue to go out of their way to make sure the Cartel's are allowed to thrive both here, and in Mexico.
