SAM:
Gitmo probably won't be closed until the administration changes. To close it before then would be to accede to common sense and moral action - not something the Bush administration is terribly good at.
What is the status of the prisoners?
Undetermined. They are classified by the government as "illegal enemy combatants". According to the government, that destroys basic legal rights guaranteed to everybody since the 11th century, such as
habeus corpus - the right to be charged and tried promptly, the right to see the evidence against you, the inadmissibility of evidence obtained by torture, etc. etc.
Battles are still being waged in the courts to determine the rights and status of these prisoners, including in the US Supreme Court. Questions have been raised about the legimitacy and constitutionality of legislation passed by Congress regarding these prisoners.
Who is accountable for them?
The US military is immediately responsible for their wellbeing. They are only accountable to the US executive, it seems, unless the courts have something to say about that in this case.
In a wider moral sense, of course, all Americans are accountable, or should be. The harm the existence of Gitmo does to the reputation of the United States should be recognised and ameliorated. Some Americans know this and are speaking out for basic human rights. Others still assume that all people with dark skin are evil and have no rights.
Baron Max:
Why? As far as I can see/hear, only the liberal, doo-gooder Americans give a shit about them. And who cares about liberal, doo-gooder Americans?
It is a pity you can't see the long-term implications of erosions of the fundamental legal rights you take for granted.
When you are locked up without charge or trial, maybe you'll change your mind.
