To my knowledge the NSA is not running drugs or involved in overthrowing other governments.
From all I have read and heard, the CIA is.
If I understand correctly the NSA is spying on everyone, which apparently included the CIA.
I don’t believe the CIA liked that. Their whole organization is very murky and I believe criminal.
Agreed.
To answer both your questions I will have to give evidence rather then opinion that I shown here. I will do that latter. Duchess you're correct the CIA has the ability to act the NSA has the means to observe. They use front companies and foreign spies to fuse the information together. They actually call it "fusion"
