GWB Admits Secret CIA Prisons

It appears that in light of the upcoming elections, the President has decided that the "secret" part of "secret CIA prisons" is no longer a good idea.

President Bush has transferred 14 key terrorist leaders from secret CIA custody to the U.S. military-run prison at Guantanamo Bay, Cuba, to be prepared for eventual trials, a senior administration official said Wednesday...Bush said such detainees provide essential intelligence to prevent terrorist attacks and to stop key terror suspects from again taking up arms against the United States. "We have a right under laws of war and an obligation to the American people to detain these people and prevent them from returning to battle," Bush said.
"They are in our custody so that they can't kill our people."

I admit to being somewhat disconcerted by this. I know that much is permissible in time of war that is not reasonable in peacetime. But can detaining anyone without trial, without counsel, and without possibility of appeal (even secret appeal) be allowed under our Constitution?
