for more on al qahtani and the remaining detainees, i spoke with "new york times" reporter carol rosenberg has covered guantanamo bay and the prisoners there since 2002. carol, why is the repatriation of al-qaani such a big deal? >> because he's been described for so many years as the 20th hijacker, the man who would have been the 20th hijacker in the september 11th attacks. and because there is still a residual sense that if he was intended for that mission, there should be some way to put him on trial, and there simply is not. he's held as what i like to call it, a forever prisoner. he's held as a detainee in the war on terror, a law of war prisoner-- essentially a u.s. category for arisoner of war that was created after the september 11th attacks that said, as long as we are engaged in that war, we can hold people that we believe came off that battlefield. and cause there's nobody to surrender on the other side, there's no formula for ending that war. this periodic review board takes a look at the cases and decides who can be sent away, sent home or sent to resettlement somewherelse wit
