REALLY?!!? Nobody has ever heard of the narcotics division of the FBI? REALLY???!!! Come on, now. Yes the DEA is the Drug Enforcement Agency, but that doesn't mean that other law enforcement agencies aren't involved in enforcing drug laws as well. Do your local police arrest people for drug offenses, or do they call in the DEA for every single case? Yeah, so I think we've established that the DEA isn't the only law enforcement agency that investigates drug offenses. Why does it seem so farfetched that the FBI would be involved, considering they have an ENTIRE DIVISION dedicated to narcotics investigations? Not to mention the FBI "Drug crime programs" that exist in basically every major city or port of international travel in the United States.
Whoever said that FBI agents aren't allowed to drink is off their rocker. I live in an area where practically everyone works for the government, and I've served drinks as a bartender to many a FBI agent at a bar not far from their headquarters.
I can't believe you people are all so deluded... really.
