I don't believe they are foreign nationals. They didn't martyr themselves. Other similar instances in Europe the bombers were martyrs. That didn't happen here. I think that is very significant.

I don't think they were prepared at all to die. According to reports I have heard this evening, suspect 2 reacted to the first explosion. That is not a man ready to die.

I heard the observation they were over dressed for the day. Not if they came from some place colder than Boston. People dress for the weather outside the door, not necessarily for their destination.

Why draw attention?
