Leaked e-mails: U.S. government works with Mexican cartels to traffic drugs into the US

Submitted by Ed Thinking: Leaked emails from the private U.S. security firm Stratfor cite a Mexican diplomat who says the U.S. government works with Mexican cartels to traffic drugs into the United States and has sided with the Sinaloa cartel in an attempt to limit the violence in Mexico.
Many people have doubted the quality of Stratfor's intelligence, but the information from MX1—a Mexican foreign service officer who doubled as a confidential source for Stratfor—seems to corroborate recent claims about U.S. involvement in the drug war in Mexico.
Most notably, the reports from MX1 line up with assertions by a Sinaloa cartel insider that cartel boss Joaquin Guzman is a U.S. informant, the Sinaloa cartel was "given carte blanche to continue to smuggle tons of illicit drugs into Chicago," and Operation Fast and Furious was part of an agreement to finance and arm the Sinaloa cartel in exchange for information used to take down rival cartels.
