And now for what really happened ... and this is only the beginning  ... at Bagram US Base in Afghanistan before Mr. Khadr was shipped off to Gitmo and where he was still ecovering from 2 bullets to the back:

"At Bagram, he was repeatedly brought into interrogation rooms on stretchers, in great pain. Pain medication was withheld, apparently to induce cooperation. He was ordered to clean floors on his hands and knees while his wounds were still wet. When he could walk again, he was forced to stand for hours at a time with his hands tied above a door frame. Interrogators put a bag over his head and held him still while attack dogs leapt at his chest. Sometimes he was kept chained in an interrogation room for so long he urinated on himself".
