One would like to hope so - but you don't get and keep a job in government with outside-the-box thinking. These guys are too busy neutralizing the last threat than thinking up new ones.

I have been writing to every agency I can think of - FBI, TSA, FAA... - to get them to at least consider the fact that enough plastique to demolish an airliner will fit in the spare battery compartment on some laptops. The machine could boot up fine and dandy (which is their sole criterion for a safe machine), but still be packed with Semtex, which has the same physical and X-ray density as a battery. The vapor signature could be neutralized with a Seal-a-Meal and scrupulous cleaning.
