There is just something wrong (certainly sad and tragic) that an agency of the United States government had secret prisons in other countries. The associated Press and a German public television, ARD Panorama, did the investigation to put the truth to the denials of the existence of Romania's CIA prison. See the AP story: Inside Romania's secret CIA prison.
Yes the prisons are closed but see this: Senate Votes To Let Military Detain Americans Indefinitely, White House Threatens Veto. We can have the "terrorists" prisons right here at home if Obama fails to veto the new legislation called National Defense Authorization Act.
And the "terrorists" include American citizens that can be detained indefinitely. A read of the story shows that there was little concern about constitutional rights. And this bill seemed to be opposed only by civil libertarians. Of all things to have bipartisan support.
