Talk of CIA prisons censored at Guantanamo hearing

US authorities censored part of a preliminary hearing Monday at a Guantanamo military tribunal that touched on CIA secret prisons where suspected 9/11 plotters say they were tortured. Reporters watched the proceedings against the five 9/11 suspects at the US naval base in Guantanamo Bay, Cuba behind a thick, sound-proof glass wall and listened to piped-in audio with a 40-second delay. But when a defense lawyer mentioned the CIA secret sites at Monday's hearing, a red light flashed on and the sound from the courtroom was cut off.
