nic, now that we have you on the phone. know there were more arrests. what ils do you know? >> what's very interesting here is these arrests are coming around karachi and because we now know his father-in-law was one of those arrested, it does focus on that side of his family and his old friends rather than where we understand his father is or at least was until recently, which is close to that town where the northwest frontier province of lawless tribal border area of afghanistan. the police have been very, very close-lipped here. normally in pakistan in situations like this, little bits of information slip out. security sources give away information. right now it's very quiet and very little information coming indeed. we've been checking on some of mr. shahzad's past here calling one source, we've been told just not to say anything right now. the government is trying to keep a lid on the detailed of what happened and why would they want to do that? because they don't want to limit and impact further arrests they might be

nic robertson spent almost a year uncovering that answer.e's a preview of his special "360" report. >> reporter: this is penn station in the heart of new york. more than 60,000 people churn through here at peak rush, 60,000 every hour. for al qaeda, penn station and the potential for a mass killing is a prize and daunting target. but then it seemed they got lucky. that's when this man, a young american, who grew up only 50 miles from here, made his way to pakistan, to offer his help. he is brian nelvenes, and this is how a middle class kid suddenly transformed into a dangerous enemy of the state. >> brian is almost a poster child for the process, the unremarkable nature of the people who might go through this process and the danger that presents. i spent the better part of the year here in the u.s. and europe unraveling how he went from catholic to muslim, from u.s. army recruit to jihadist, from long island to lahore. he grew up on this street, in a middle class neighborhood on long island. his parents, latino immigrants, neither would go o

he has worked with nic robertson on ac 360 special american al qaeda. which begins on monday.r is a best-selling author whose book includes "holy war on the home front." and jack rice, criminal defense attorney and investigative journalist, a former cia officer. okay. jack, we'll start with you. the most significant thing we have learned about shahzad so far is what? >> most significant thing that we really have on an international basis is there is this connection of pakistan. earlier, we had no idea whether this was a lone wolf or not. but if there is somebody rolling out of pakistan now, the investigates continues domestically, but we also have to look internationally now, because the resources are different, the connections are different and where he may have come from, who may trained him and who may have driven him into the states to do what he has done. all of those are issues that we have to really look at very closely now. >> larry: paul, is this -- what is the thing that most surprise use about all of this? >> well, the most important thing about all of this is his c

guys, i want you to listen to what the homeland security secretary janet napolitano told our nic robertson to this little clip. listen to this little clip -- >> there are young americans who have gone through a process and breaking away from, you know, the community in which they were brought up, traveling to pakistan, maybe afghanistan, going to a camp, learning how to conduct military-type operations and then coming home. and, like i said, if we don't have any other information about them, they're free to travel. i mean, they're american citizens, but it is something about which you need to be situationally aware in case they go from becoming radicalized in thought to becoming violent in action. >> how do you -- >> it's sort of chilling, donna, to hear that, knowing what we now know about faisal shahzad. >> well, wolf, i think it's a reminder, once again, that we face an enemy that is hell-bent on destroying this country, that will exploit any divisions within this country, and that is radicalizing certain youth in this country. so, i think this is, again, a reminder that we all have to,

thanks very much, nic. [applause] >> he was just a century ahead of his time, that's all.he next 50 years that we're going to see all of this. there are microphones. with the light shining in my eyes, i can't see where they are, but i am confident that they're there. there are also green question cards that you can fill out and hand either to one of the panelists or to one of the staff who will pick it up and bring it to the panelists. and let me start, if i can, by going back to a theme that a couple of you have touched on and that is that this stuff isn't going to happen overnight. dr. wolter has been doing this for sometime but some of of these to demonstration pilots are going to take time to organize and get some return on investment flowing. is there the political patience -- i don't know if i should be asking you or the audience to allow that kind of development to be talking about two date groups, start to change the culture and actually deliver some results. gail, you want to start. >> i worry about that. and that's why i caution against what seems to be wildly op
