Oh look: a high ranking U.S. drug official in Mexico also "served as a secret ally of traffickers while he was posted in Guadalajara." Specifically, Richard Padilla Cramer used his post to report DEA informants to big drug cartels, for cash! The druglords would use this information to kill said informants in gross and painful ways. This, of course, comes as a "Complete Shock" for anyone who hasn't noticed that every DEA agent in Latin America has done the same thing, for the same reason, forever.
Meanwhile this week State Department listed Venezuela and Bolivia among the top three worst drug offending countries in the world for not cooperating better with this same top-secret DEA drug-running thrill kill cartel, the end.
