Corrupt Practices of the CIA?

Okay so I'm doing this project on how the CIA's practices are morally unjustified. I have (for evidence) Project MK-Ultra, but I need more than that. It also needs to be TRUE and I have to have a bibliography. We all know MK-Ultra was DEFINITELY underway and is 100% true, but things like accusing the CIA of 9/11 and whatnot are just (in politically correct terms) "conspiracy theories". I need TRUE evidence. Oh, and preferably at least 20 years old
