I suppose that theory would make sense, especially if it's a situation where the terrorists/insurgents had stumbled upon some kind of stockpile of these munitions and didn't realize what they had. A possibility that Kimmett himself apparently believes.

If that is the case, I think it's logical that we'd want to follow them back to the source, rather than taking them into custody and trying to get them to just TELL us where they found it.

On another note: Kimmett just gave one-on-one phone interview with Linda Vester and re-confirmed all of the info. I'm guessing if it was something that was that highly classified, the Pentagon would have shut his trap by now.
