According to David McClintick ("Swordfish: A True Story of Ambition, Savagery, and Betrayal"), in the late 1980's, the FBI and DEA set up dummy corporations to deal in drugs. They funneled into these corporate fronts money from drug-related asset seizures. The idea was to infiltrate global crime networks but a lot of the money in "Operation Swordfish" may have ended up in the wrong pockets. Government agents and sheriffs got mysteriously and filthily rich and the whole sorry affair was wound down. The GAO reported more than $ billion missing. This bit of history gave rise to at least one blockbuster.
