Any thoughts on what should happen with Gitmo detainees who aren't prosecutable?

You probably know the deal- Many of the Gitmo prisoners have already been cleared for release, but can’t be safely returned to their countries. Many others will never be convicted in US federal courts because of insufficient, faulty or coerced evidence. These are all people whom we will soon have no legal right to detain, but whom we ourselves may have transformed into mortal enemies, if they weren’t already.

Let’s just take it as a given that we had no business collecting many of these guys in the first place, and that the whole Gitmo strategy was a bad legal idea.

Realistically, what now?
