Well, it is the beginning of fulfilling one of The ONE's campaign promises. He'll probably set them free or turn them all over to The World Court in The Hague (which would basically be the same result).
Of course, I'm sure there are some lefty wing-nuts out there who will want W, Cheney, Rove, and some of the FoxNews editors put on Trial for War Crimes in which case The ONE will have to re-open Gitmo to house them.
