Does IranContra ring a bell ? the CIA pushing drugs in the minority community in the 80s ? Now the CIA is supposed to be handling foreign issues - but they're doing this in their homeground. Now imagine what they're doing in other foreign countries.
Then take the DOD which has failed multiple audits - you know how dysfunctional you've to be as an org to fail audits ? and the amounts are in the trillions. Even though the CIA is not part of DOD - just to throw that there.
