Second thoughts on Guantanamo?

Now that Obama plans to close Guantanamo, what should we do with those prisoners that are dangerous? The Brookings Institure proposes that they be held indefinitly under a new detention law crafted to fit the situation. Some might argue that this isn't much different than the current situation. Hopefully under the clean start of a new administration we can have a intelligent reasonable discussion about the future of Guatanamo.
