Something like that. IIRC, one of the guys that supposedly the ATF wanted to nail was an informer for the FBI.
As proof, he suggested that the Feds know every drug kingpin from Columbia right up through Mexico but when the drugs cross the USA border, suddenly there are no drug kingpins. They just disappear. No, not the thousands of low-level pushers but the guys who move tons of drugs seemingly right under the noses of the specialized police forces.
When is the last time an American citizen has been arrested for major drug distribution?
Just a little to ponder about the entirely futile and unsuccessful War on Drugs.
