George Bush killed more than a million people and got away with it. One of his soldiers shot a Koran for target practice, however, and he was prompted to formally apologize.
The CIA tortures, but as was the case for Nixon ordering goons to break into Democratic HQ, torture isn’t the problem–it’s all about the cover-up. In this case, the Justice Department is after the CIA, not for torture, but for destroying tapes of torture. America is weird.
