mall s control room with its closed circuit cameras giving them eyes everywhere and the knowledge they were in control. they were acting as if nothing was really happening. no emotion? no emotion. no nothing. just strong face and they didn t appear like they were bosses. reporter: among the many questions is whether some terrorists might have slipped out in the mayhem, possibly trying to leave the country. now kenyan authorities are stepping up security all along the country s borders and here at kenya s main international airport. ten suspects are now in custody. international forensic teams entered the mall looking for any clues about who exactly was behind the terror. alex marquardt, nairobi. really hard to believe that they had a store front essentially for a month bringing weapons in. smuggling them in the whole time. seeing how the mall works every day. planning it out very casually. there s been a lot of critics of
many different directions. and i assume a facility like this, the u.s. neighbor yard, the naval sea systems command, what s called building 197, lou, would have extensive video cameras. it takes awhile to go through the videotape to look at those closed circuit cameras and find the images that you you desperately want to see? yeah, absolutely. i mean, based on just the agreography if i of this facility, there s a lot of work involved. they already know, for example, where the shootings have taken place. so they can immediately target those cameras that were focused on that area. and start this investigation. they re going to want to branch this all the way out to the perimeter to see how and when these individuals accessed this facility. this complex. hold on for a moment, lou, jake tapper is over at the scene where we saw the news conference just a little while ago from the d.c. mayor, the k.c. police chief, the chief suggesting two
