The CIA destroyed the videos they made of the interrogation of Murat Kurnaz.
When someone destroys documentation, the legal presumption is that the material was incriminating. In addition to that presumption, there are these documents:
On balance the evidence of Kurnaz's innocence is robust. In addition the destruction of evidence by the CIA and the correlation with other stories and verified evidence make him far more trustworthy than the US military.
So, I believe this CBS News 60 Minutes story of his five years of imprisonment, and years of torture: Ex-Terror Detainee Says U.S. Tortured Him, Tells 60 Minutes He Was Held Underwater, Shocked And Suspended From the Ceiling - CBS News
Note this part of the story, which took place in Kandahar Afghanistan ...
They used to beat me when my head is underwater. They beat me into my stomach and everything," he says.
"They were hitting you in the stomach while you're head was underwater so that you'd have to take a breath?" Pelley asks,
"Right. I had to drink. I had to…how you say it?" Kurnaz replies.
"Inhale. Inhale the water," Pelley says.
"I had to inhale the water. Right," Kurnaz says.
Kurnaz says the Americans used a device to shock him with electricity that made his body go numb. And he says he was hoisted up on chains suspended by his arms from the ceiling of an aircraft hangar for five days.
"Every five or six hours they came and pulled me back down. And the doctor came to watch if I can still survive to not. He looked into my eyes. He checked my heart. And when he said okay, then they pulled me back up," Kurnaz says.
"The point of the doctor's visit was not to treat you. It was to see if you could take another six hours hanging from the ceiling?" Pelley asks.
"Right," Kurnaz says.
Let us assume "the doctor" is an American MD. The number of physicians who served the US military at Kandahar Afghanistan cannot be that large. It should be possible to track him down, and bring him to justice. At the very least, his medical license can be revoked.
In turn, he will implicate others.
It is not inconceivable, though it is unlikely, that one day George Bush will be called before a war crimes tribunal. We might as well gather the evidence.
