This has been quoted a few times already, but I think it's worth repeating:
"Nowak has yet to make an official visit to Iraq and said such a mission would be unfeasible as long as the security situation there remains perilous. He based his comments on interviews with people during a visit to Amman, Jordan, and other sources."
"You find these bodies with very heavy and very serious torture marks," he said. "Many of these allegations, I have no doubt that they are credible."
So, you take someone else's word for it, and then proclaim it must be the truth?
(I saw it on the internet, so it must be true!) Sheeesh!!
