pete, are you still there? is pete still there? we don't have pete. jonathan, i'll pose the question to you for folks who may not be -- oh, pete is this. how customary is this, pete? i think we heard kristen welker, quite frankly, there are a number of suspicious packages received at these facilities. >> there are and the field tests almost always are wrong, so we have to wait and see. i remember one incident where there was enormous concern about a letter possibly containing anthrax and it turned out to be paper dust. so we have to sort of, all the systems are working right here. they're obviously set for a very low threshold to indicate something positive, so they're waiting to see. think about all the containment here. none of these got to the recipients. they think they know who the sender is. they were stopped. they're testing them now. ricin is very different from anthrax. you can get symptoms if you just touch it. if it's in the air. ricin, you have to ingest. so, it's a completely different kind of thing. it's threatening, it's poisonous, dangerous, but we still don't know if that's what we're dealing with here. >> as we wait on these result, we are also

pete says, this is something that was discussed in the wake of oklahoma city. does this change things measurably? >> first, let me congratulate pete. i think there are three petes out there. >> pete has led the way this past week, he's an american hero. >> i'm grateful for that. in some ways, this case is the harder case. you're talking about not one lone wolf, but two lone wolves, if that's what's happening here. who kind of cooked this up on their own. when that happens within a society with 300 million people, it means almost by definition, they're hard to find. and the only way you can find people like that in some ways is getting into their thoughts and to be very, very intrusive. i kind of think what was the sci-fi movie "minority report" when they could predict who would commit a crime in advance and arrest them beforehand? one of the waz you could reasonably interact with these two lone wolves to be, a year or two years, five years ago, in a way that would have been effective, we can still see if the fbi, if what they're saying is accurate. they took every step they could. every time russia raises a red flag about somebody, i'm not sure i want to give the fbi the tools to sort of go in right there when russia has its own interests. but at the same time, at the same time, you know, these guys while they managed to send a whole city into lockdown, they didn't accomplish any strategic or tactical means from the perspective of al qaeda. in one way we don't, one way we don't want to overreact as horrific as this were, for the victims that they, that were part of this. >> on the question of how they executed this, pete, in terms of resourcing, there seem to be some questions and peggy noonan raised some in today's "wall street journal," about where these guys were getting the money to buy the instruments with which they made the bombs. to have the lifestyle that they did we know that tamerlan tsarnaev had a fancy car, i think it was a mercedes c class. you know, their parents were in russia, they were divorced, they were not a family of considerable means. do we have any more intelligence on how they might have procured the funds to do all this? >> well that's one of the many questions they'll be looking into. every time i ask for information like that, somebody always says, that's why we call this an investigation. that's one of the many things they'll be looking at. this he don't have all the answers yet. >> pete williams, american hero and msnbc reporter. >>> the question i have is how much the country will want to see things changed as a response to this kind of the answer we give the country fo
