we don't know what they got, if anything. >> brown: bruce hoffman, who were they talking to? how does one pursue all these leads and what kind of resources does the american government have to marshal to pursue them? >> again, certainly any communication on the computer will be enormously important and in the attempt of tamerlan, who may have had traveled abroad where he may have gone and who he would have met with. but it all bips down where and how were these individuals radicalized and were there connections? we haven't heard much of the third suspect taken into custody this morning. that may be an enormous link to this as well. >> brown: or not. >> or not. precisely. >> brown: the lone wolf type i think we heard referred to earlier, that has to be -- that's part of the pursuit as well to see who they are and how they might have gotten. >> president pat type of terrorism has gone one way or the other. it has turned out to be general lone wolves, autodidacts in bomb making and weaponry, self- radicalized but all this sounds remarkably like the situation and scenario after t

as researchers like bruce hoffman and paul berman have documented, terrorism is designed to achieve through it can't achieve through a conventional military campaign. it's designed to make all of us feel victimized, afraid and ultimately less committed to our open society. now, i think we defeat that goal every time we reach out and help each other and work together in response to an attack like this or other incidents. and when we look at that, the physical heroism at the scene, or the communal contributions made from afar, it all counts. every person who submitted a photo now has made a contribution. now, alone, each item might be fairly useless. together, though, the hundreds of thousands of items might inform a larger picture, a moization of intelligence that could break open a lead in this case. i wouldn't call it bystander-generated evidence. we're not bystanders after we take action and we work together. we're not defined by what happened. we start being defined by what we're doing. we become part of the investigation. part of the rebuilding. and part of an american tradition that do
