"The latest CIA scandal will once again teach Americans a valuable lesson: It is the CIA, not the Congress, that is the ultimate governing authority in this nation. No one messes with the CIA, and the CIA knows it. That's why it knew that it could destroy CIA's torture tapes without asking anyone's permission. And, after all, as Richard Nixon's advisers told him, better to take a bit of heat for destroying the tapes than to take the heat for what the tapes contained."
