It seems that the version of Abu Ghraib peddled by human rights groups is false, too. In this case, an officer was convicted of disobeying orders concerning the discussion of that case. He was acquitted, though, of much more serious charges (failing to control Graner and the other MPs who misbehaved).
Then again, the human rights groups are less concerned about justice, and more interested in tying the hands of our interrogators. Never mind that the techniques used may be needed to stop the next 9/11.
Unpleasant? Yes. But a few roughed-up terrorists is a lot more pleasant than a major terrorist attack.
