Extra Credit of Rendition

I don't agree with torture; in this movie the man was completely innocent, but he still said that he did it just to make the torture stop. So, how valid is the information from doing this. Also, they treated him better as a terrorist than when he wouldn't give any answers. What message is this sending? Another thing when he returned home there was a complete change in him. After something like that no one would ever be the same again, and in this movie he wasn't the same man after this. Lastly, this doesn't just affect the person in torture, this also affects the family. He was an American citizen, with an American family, but yet no one was told what happened to him, they didn't know if he was alive or dead. How is this fair to anyone?
