Drugs are but one facet of the cartels' web. They are into extortion, prostitution, gambling, smuggling, etc. If drugs are legalized they will merely shift into another area.
The extortion, prostitution, and gambling is on the Mexican side of the border. Why do you care about that?
Are you fucking joking?
From 20,000 feet there is no difference between Juarez and El Paso - that's the same all along the border.
These are integrated mega-communities separated by some artificial legal constructs. The peoples' families are on both sides. They are US and we are THEM.
I'm not sure that's saying it right exactly....
