joining me now is evan coleman and roger cressey. r, they lived in the united states for ten years. we've seen similar stories of radicalization. how does it happen? >> they didn't come here already r radicalized. we don't know if it was external sources, personal struggles, family issues, they are perceived as religious or ethnic duty. these are all possibilities right now. but we've seen in the past, be it with the faisals of the world, he was a citizen. he came from pakistan. he was radicalized because of the u.s. war against al qaeda and effects on that and the tribal region where some of his family was from. he was trained by pakistani taliban and came to the united states to try to attack the times square. that's a classic situation where we thought someone who was folded into the fabric of american society but ultimately became radicalized for political reasons. we don't know if that's the case for the tsarnaev brothers. >> that was going to be my question. we don't know if they were radicalized. there's no statement or manifes

we're joined now from washington by nbc news terrorism analyst, roger cressey. roger, tell us for a moment, if you can, an chechen terrorism. because as i understand it, historically chechen terrorism has been much more related to national boundaries and geography as opposed to any kind of hatred for the united states. >> martin, that's exactly right. and i'm hesitant to even call this chechen terrorism yet. what i will call it is the act of two individuals in an act of terrorism. we simply don't know whether or not there are any real direct links. but in chechnya you've had two phases. a separatist movement since the end of the soviet union that over time has morphed into an islamist movement. in the past 15 years, elements of al qaeda have fought there. bin laden when he was still alive pledged public support to the islamists fighting there. and we saw even pre-9/11, an amalgamation of chechen fighters into al qaeda camps, et cetera. it doesn't mean there were broad alliances or strong cooperation between both forces. it just means there was this interaction. s

roger cressey, we've been watching this new video coming in from cambridge, massachusetts, dogs are there. we were just talking about potential use of robots. we've also seen cycles of activity. kerry sanders, about 30 minutes ago, 40 minutes ago being pushed back successively and now he's saying, it's quieted down a bit. should we expect to see this ebb and flow? >> well, it's always a possibility, richard. i think with the law enforcement officials and the negotiators, if they're involved right now, it's assessing the situation, see what the chances are, if the individual is still alive to get him to surrender. because as james and clint have both said, there is a very real possibility that he will take his own life and attempt to take the lives of others around. the madrid, the madrid experience is actually an instructive one. and there is always this, this tendency to rush in, and every sense of the word. and if this is a, if this is an individual who has gone through the process of putting together, assembling additional devices, who is planning to do additional attacks, they have to

former deputy of counterterrorism on the national security council, nbc news terrorism analyst roger cressey. roger, let's talk a little bit about sort of how this all came to be. i mean yesterday, i think the entire post monday, the entire investigation got a sort of huge bump up if you will when the fbi held their news conference and revealed at least the identities, if not the names more biographical information, the faces of those suspects in this bombing. i thought it was really interesting that that we got that tape that was apparently taken from lord and taylor. we also have gotten reports about bystanders who may have been critical in, in actually helping pinpoint who did this. >> there's firsthand eye witness accounts, coming from people 40 were in the hospital, who in all likelihood have helped the fbi with this investigation. >> yeah, alex. it really is remarkable. the speed with which this is, has gone since the fbi press conference. and special agent in charge, deslauriers said repeatedly, somebody knows these individuals, family, friends, acquaintances, workers, colleagues. and

let me bring in roger cressey, nbc news terrorism analyst. roger, we heard in great detail from pete as much as possible the latest from this charge sheet for is dzhokhar tsarnaev. the question remains about this fbi investigation. you have lawmakers wondering if there was a crack, if you will, in the fbi process when they went to the family's home and interviewed if you will, tamerlan tsarnaev. what can you tell me about any information you have from your sources? >> well, this is going to be part of the investigation into the why. that will go on for some time here. because you have both the fbi as well as the intelligence community and other national security bureaucracies going through the data bases, identifying the information that they had on hand at the time of the bombing. and now cross referencing it with what they know from the tsarnaev brothers in their actions and activities. based on what we've seen in the initial reports, based on the fbi statements, they followed the normal procedures the right way. >> what is the normal proced

we're joined now by michael isikoff who's in boston and by nbc news terrorism analyst roger cressey. you. mike, we've been hearing a lot about the mother, but now i understand you have some information about tamerlan's wife. what can you tell us? >> reporter: exactly, martin. earlier today, fbi agents went to the home of the parents of catherine russell, wife of tamerlan tsarnaev, questioned her for about an hour and left with bags of evidence. now, her lawyer says she's cooperating with the fbi but she's clearly a crucial witness, as agents try to piece together at background of tamerlan tsarnaev and his activities in the month leading up to the bombing. she has, was working during that time. they had a 3-year-old daughter. the parents were taking care of the daughter. but where was tamerlan during h this weirperiod? what was he doing? how much time did he spend at home with his daughter? how much time did he spend away? what did he tell his wife about where he was, who was he meeting with? these are crucial questions as fbi agents try to piece together the whole story here. clearly

this is about the game right now, roger cressey. >> so what you're going to see here if in fact this is the subject and is not captured but is ultimately dead, we're going to get additional pieces to help explain the why. and what you're seeing is tremendous effort in going after cell phone records, communications, computer records, all the type of pocket litter that the fbi would find at the house and if there's anything else on this individual if in fact this is him, then is helps to better round out the picture so we can better understand why they did what they did on monday. >> clint, it's like in sports between an air game and ground game, we were told on monday and tuesday as we began covering this horrific bombing at the boston marathon finish line that they were going to go by granule by granule, various pieces of bomb that are able to be recovered. all kinds of physical evidence that they are going through and some sort of very slow, very deliberate effort to some day reach the person who bought this material. however, we've seen the speed with which this apprehension has go

roger cressey joins me.ou. >> you, too, alex. >> we know back in 2011 the fbi was asked by a foreign government to investigate tamerlan. he was preparing to travel to join some underground groups reportedly. how unusual is it for a foreign government to make a request like this? >> it is unusual at all. it's a little unique when the russians do it and that's what make this is so different because if it's a western ally with a level of cooperation we have with intelligence sharing and law enforcement cooperation, there's a more, if you will, open and relaxed exchange of information. but certainly when the russians are asking about someone who might be related to the chechen conflict, while we'll go through our process to see if there's any information there, in the back of the mind of the government has to be what would the russians do with this information? given their tremendous amount of internal strife and civil war that's been involved in the chechen region. that's not to say we wouldn't share anything.

back with us now, nbc news terror analyst roger cressey. he served as a top official in the clinton and bush administrations. let's go back to what we were about at the top of the show. john boehner last week, as well as some others expressed concerns about data sharing. and we know that russian authorities got in touch with both the fbi, the cia, about these alerts. but was that information to your knowledge and feel free to speculate here, would that have been shared with the other agencies that might be relevant for those kinds of concerns and do you think we have a problem sharing intelligence right now? >> the answer is yes. it would have been shared. it would have been brought in to agencies such as the national counter terrorism center whose sole purpose is to ensure proper coordination of intelligence and then counter terrorism policy. and this is an organization that, where every agency who has a role in counter terrorism is represented. the two dozen plus data bases were all could you pleaser terrorism data resides, feed into the
