Certainly no government would ever encourage its own agents to engage in things like smuggling especially the smuggling of drugs to certain Global South nation states where the capital acquired from those operations end up funding pro-American paramilitaries who topple their local government. That would be totally bananas for any kind of republic.

Contra-ry to common conspiracy theories, I'm certain any government-led self-investigation into culpability in this vein was all very aboveboard and well-substantiated, and such incidents never ever happened.
