“Well, for one thing, it is necessary that people in our military understand fundamentals--the people in the appropriate units in the military understand the fundamentals of how bombs are made and how they can be defused and the technology of it. And of course, I think the people in the military do the best they can to make sure that the rigorous training program that people go through would sort out those who are unsuited. It is true that some of the people who have the knowledge necessary to cause problems for us domestically, in instances of domestic terrorism, have been in the military. But I don't know that we can compellingly say that there's any higher percentage of people who are mentally unbalanced who have been in the military than in any other group. And I don't know that there's any sort of screening process that the military could adopt that would protect against that. That is something that--I think that's one of the ongoing questions they're always asking themselves whenever we have an incident not just involving a bomb, but if there's something else that a soldier does or a veteran does that may seem tied to his or her military service, they look at that. But I don't know that there's an easy answer to that. Mara [Mara Liasson, National Public Radio]?”
