Mr Bush forestalled the Europeans by raising the issue of Guantanamo Bay at the summit, saying that he understood their concerns. He spoke of his "deep desire to end the program", adding: "I'd like to end Guantanamo. I'd like it to be over with."
Some of the inmates would be returned to their home countries, he said. But "there are some that need to be tried in US courts. They are cold-blooded killers. They will murder someone if out on the street."
So, presumably Bush believes that "some" or even "most" are not "cold-blooded killers." In fact, it sounds like they haven't even committed offenses which would merit being tried in a court.
How long have they been there?
