It's because violence amuses him, that's why.

An e-mailer brings this eye-opener to my attention:

Before he was transported from Bagram to Guantanamo, Omar Khadr was dressed in an orange polyester uniform and hog-chained: shackled hand and foot, a waist chain cinching his hands to his stomach, another chain connecting the shackles on his hands to those on his feet. At both wrist and ankle, the shackles bit. The cuffs permanently scarred many prisoners on the flight, causing them to lose feeling in their limbs for several days or weeks afterwards. Hooded and kneeling on the tarmac with the other prisoners, Omar waited for many hours. His knees sent intensifying pain into his body and then went numb...

In the interrogation room, Omar’s interviewer grew displeased with his level of cooperation. He summoned several MPs, who chained Khadr tightly to an eye-bolt in the center of the floor. Omar’s hands and feet were shackled together; the eye-bolt held him at the point where his hands and feet met. Fetally positioned, he was left alone for about a half hour.

Upon their return, the MPs uncuffed Omar’s arms, pulled them behind his back, and recuffed them to his legs, straining them badly at their sockets. At the junction of his arms and legs he was again bolted to the floor and left alone. The degree of pain a human body experiences in this from of “stress positioning” can quickly lead to delirium, and ultimately to unconsciousness. Before that happened, the MPs returned, forced Omar onto his knees, and cuffed his wrists and ankles together behind his back. This made his body into a kind of bow, his torso convex and rigid, right at the limit of its flexibility. The force of his cuffed wrists straining upward against his cuffed ankles drove his kneecaps into the concrete floor. The guards left...

One can just imagine Blogging Tory and violence fetishist "Neo Conservative" reading that and reacting, "Oh, yeah, oh, yeah, oh, yeah, unnggggggghhhh ... um, honey? Could you bring me some more paper towels? No, no, don't come in, just leave them by the door, thanks."
