[mware]

I recall very early on, one of the reporters mentioned that the bomber was acting as a mule for the attack and someone else set the bomb off. He didn't seem to be guessing at this.

I suspect this was one of the pieces of information they didn't want floating around that early in the investigation.

That’s a GREAT piece of information to get out. Unless you’re a terrorist puppeteer. Far from a fix, but I bet it will discourage a lot of terrorist “helpers” who have no idea they are about to “volunteer” to be a suicide bomber.
