Drug cartels allegedly have turned Doral, FL "into a money laundering haven that has empowered the largest criminal organizations in the Americas to hide their illicit profits and dominate the narcotics trade in the United States" by using export companies as reported by USA Today. The scheme -- dubbed the "black market peso exchange" -- is simple. A South American electronics retailer places an order for cellphones or laptops with one of the export companies located in the Miami suburb, and the invoice is paid within the United States through a wire transfer -- or bulk cash -- from drug proceeds. Once the overseas retailer receives the merchandise it pays back the Colombian narco "the equivalent amount -- in pesos." Many of these export companies are blissfully unaware they are laundering drug money, some may be willfully ignorant and perhaps others have a good idea.
