Sure wish 'Release the innocent people on hunger strike' was an option but I guess this isn't the America I used to know.
Hasn't really been an option since 2002 and the whole legal ball of shit was first crafted.
There are 86 prisoners who have been cleared for release but can't be sent anywhere thanks to a mix of congressional and DoJ blocks. The rest of them are people either in court now (the 9/11 trial is ongoing) or who simply can't be prosecuted because of how they were captured and treated, but who the USA feel are too serious a threat to release. How to deal with that last group of ~50 is something no-one wants to touch.
I've even seen substantial arguments that any transfer of those prisoners would be a threat to their human rights and living conditions.
Seriously. That's from a senior DoJ lawyer known for advocating the closing of GTMO and who works for Human Rights Watch on counter terrorism issues.
One interesting point here is that Obama made noises about finally repealing the AUMF; the declaration of war on terror that all current war powers (including detention powers) flow from. If that were to happen then the authority under which those last people are being held would evaporate unless specifically replaced in some new law. If, by some miracle, that were to happen then it would force a solution to be found. It also feeds into the wider debates about drone strikes and executive powers that need to be had out in public and, more importantly, congress.
