scenes, if i may say so, in the book about how frank finally gets a case against his nemesis khalid sheikh mohammad2007 and you know, obviously he has got a lot of strong feelings for mohammad. but he started by being very friendly and open because the traditional fbi way of building rapport with your target, you want to be nice to them so they can talk to you. so pellegrino explains to ksm, i was the guy who is chasing you in pakistan and i was the guy chasing you in qatar and the philippines. khalid sheikh mohammad looks at him and says, so you were the ones? and even told pellegrino that when they almost got him in qatar in 1996 that ksm knew which hotel pellegrino was staying in. he relate to somebody when he left the interview that it -- chills went down his spine, that he sort of felt like he had been the hunted instead of the hunter. >> is pellegrino still in the bureau? >> frank is still in the bureau, yeah. i actually said to the fbi do you really want the front page, the first page of the book to say this is the book the fbi did not want you to read? part of it is institutional bureaucrat

khalid sheikh mohammad was at the first table.y took the lead from him as to refuse to speak, to not put the earphones in, to listen to translation, and i think that once they followed his lead they knew what they were up to. they knew what they would do that day. martha: they used to time, every moment to communicate. >> absolutely. martha: i hope you'll come back. >> i'd be happy to. thank you for having me. bill: our best to you john. it is a dawn of new socialist day in france, and why that could have serious repercussions on your retirement here at home. we'll explain that in a moment. martha: a disturbing discovery, a woman and her three daughters disappear. why is this close family friend considered, perhaps involved and now considered armed and dangerous? >> good person overall. i mean did you have any problems with him. >> i ain't never had no problem with him. martha: could it be, fewer hassles for more airline passengers? the tsa is reportedly expanding their pre check program to reach 35 of the nation's biggest airport

they were there with other 9/11 families who got to see khalid sheikh mohammad in person when he claimed responsibility for the terror attacks that through 3,000 lives. their son christopher was up with of the victims. >> they stood up and said we're guilty. we're proud of what we did and would do it again. >> we expected them to behave in this same manner. >> reporter: they were invited to watch the gitmo arraignment via closed circuit tv at an army base in new york. >> why are they putting up with the shenanigans. >> reporter: it contained drawn out legal arguments the refusal to answer questions and whether female prosecutors should cover their hair and legs. >> it was outrageous. >> reporter: they wished the military would permit tv coverage so others could watch as they are. >> why should americans be able to see and hear this trial? >> because this is part of our history. this is about an attack on america. it should be open for all americans to see. engine 54 heading down west street. >> reporter: a passerby snapped a photo of his son's fire engine rushing to duty that day. photos

you can say i give you full credit, but if you had bent decider in chief when we captured khalid sheikh mohammadbeen no intelligence which would have led us there. megyn: is it fair game putting the killing of bin laden in a political ad and taking the additional step of saying mitt romney would not have killed him. >> absolutely not. i had no problem at all with president bush referencing in his act because it wasn't a single act, it was the leadership following 9/11 whether it was the patriot act. it was an act of leadership. let me say this about the killing of sam. america rejoices in the fact that our president gave that command. but the american people have to realize where the president was when the attack was going down. he was playing golf at andrews air force base. he was called back to the white house while the attack was underway. if you look at the official photo released by the white house, historic photo marking this president's great act of killing usama bin laden. he looks like he's late to a movie. he's not sitting in the command and control room in the situation room. a genera
