Yes, for humanitarian reasons and that's the US government should do if still has some rest of decency. As others have said, torture neither is admissible nor is constitutional.
So do you support letting anyone who has been put in solitary out of prison? just because its humanitarian? because he faced nothing different than many others have.
Of course im not really in favor of the solitary system, but just because its wrong doesn't mean anyone who has been put there should be let out of prison totally.
