I think these guys were "the evil doers" but not the evil masterminds. After the Bowie incident, the big guy split and they went on to do "stupid" $10 mil tricks. They may be "stupid" but they're not that stupid. They sacrificed themselves and that equates them to the suicide crew of 9-11.
They'll clam up just like Moussaoui and Reid and I wouldn't be surprised if they try to defend themselves. It's a suicide mission waiting to happen.
We have a piece missing by the way. How did they come up with the license plate in the first place?? The truck driver might have ID'd the vehicle at the rest stop but that's all he did. The clues from Alabama were insufficient. Someplace there's a tipster who is in "protective custody". Who??
