Terror Experts Analyze Boston Manhunt
Authorities said they were looking for one of the Boston Marathon bombing suspects Friday morning in the area of Watertown, Mass., after a violent confrontation overnight left the second suspect dead.
Officials said the two suspects killed an MIT police officer, injured a transit officer in a firefight, and threw explosive devices at police during their getaway. (Read More: One Boston Marathon Suspect Dead, Another at Large)
Massachusetts Gov. Deval Patrick ordered the entire city of Boston and some suburbs to stay inside while the manhunt continued.
10:45 a.m. - General Barry Mccaffrey (Ret.), NBC News National Security Analyst.
"This has been a very dangerous Islamic region - not just Chechnya, but the north Caucus countries. Right now, the big question will be not just who were their local collaborators, but to what extent were they encouraged or supported from foreign terrorist groups."
"My assumption is that these people were alienated by their non-assimilation in this culture but probably were linked in some way, either stealth-radicalization over the Internet or directly encouraged and shaped by foreign terrorist organizations."
10:05 a.m. - Van Harp, former assistant director of the D.C. FBI Field Division.
"I think there's a question of where the explosives came from. Everyone should remember the nature of terrorism - they want the highest profile they can obtain, they are out making a statement, they are creating fear. It's the maximum impact. You have the equivalent of a dead man walking right now. I think the police and the FBI need the information from the people that are inside and around that perimeter. Anything unusual, call it in right away."
"As long as they're on the move, they're going to make a mistake, they're going to do something that is observable, that is detectable and should be immediately reported."
9:40 a.m. ET - Mitchell Silber, executive managing director of K2 Intelligence.
"(Authorities) are pretty close. I imagine this will be resolved in the next 24 hours at maximum. The only remaining question is are there other assailants out there, other people who were part of the support network who helped them plan this. Were there friends and family who maybe knew about this but didn't want to bring it to authorities and to some degree they played a passive role. And that's one of the things that authorities are going to be trying to find out."
8:40 a.m. ET — Philip Mudd, former deputy director of CIA's Counter-terrorist Center.
"I suspect that this is going to end in death. This individual has lost his brother, he's come to this country to commit an act of terror. He didn't leave the scene—that is Boston—when he could. My guess is that he's either going to die from suicide or he's going to be killed by police."
"This looks to me like a closed cell. We haven't seen more than two brothers. Only two people appear every time. One is 26 one is 19. That tells me that you probably had a radicalizer here, that's the older brother, who persuaded the younger brother to do this. They don't seem to have engaged, at least at this point, to have involved another operator."
