Easy answer... What the CIA did. He would be able to raise his hands above his head and dress himself if that was how he was treated. I don't agree with JohnnieMac but I understand the principal he is espousing. He is free to voice his opinion and try to persuade people to agree with him... even if he is wrong.
Except he isn't just a person voicing his opinion. He is a highly placed representative of our government, and his opinion hinders the efforts of agencies trying to keep us safe in a dangerous world.
