Obama is expected to close Guantánamo. He said he would during campaigning and there's no reason to doubt him now. Detainees will be sent home where possible: I don't like his proposal that some should then be deported to the US to be tried in special courts. But I do like the idea of military personnel, lawyers, politicians and certain journalists facing human rights prosecution for their wide-based complicity in the illegal detentions: I doubt however Obama will go that far. But he should. America must atone for its failure to be better than our enemies.
Meantime, watch one of the vicars of the Church of Atheism, Christopher Hitchens, do something useful for a change, getting himself waterboarded (ie tortured) by US "captors". The things people will do for the greater good of career!
