Leave them in gitmo, for life.
Let them have war trials, like the Geneva conventions ask for, and then make them serve their time there.
It will cost less and remove any possibility of contact with Americans.
I personally think that Yousef and Moussoui should be sent to Gitmo as well.
Closing Gitmo is dumb. It is just pandering to his base.
Gitmo is a jihadist recruiting tool and gives thesee dickheads hope for getting out.
Trying them in the US system and giving them life sentences in a maximum security prison is the answer.
They are no longer a problem, they aren't highlighted on the news. The Red Cross isn't all over it, nor is al-jazeera.
They are given life sentences, and never heard from again. Besides, this eliminates the chance that the NEXT president will release 2/3 of them, Like bush did.
