Testing the Soft Underbelly?

This news item from CNN about an airport in West Virginia being closed because two bottles of liquid in a Pakstani woman's carry on bag tested positive for explosives shouldn't be a surprise - assuming that the contents are in fact dangerous. Remember, at least some of the 9/11 terrorists started their day of infamy in small regional airports where security screening is assumed to be less strict. Another less-dry run? Perhaps the suspect is a mule, and was given the stuff by someone else with nefarious purposes.

Common sense says that if a terrorist or terrorists are going to try and pull their crap, they're not going to try to get through security at JFK - they'll use a smaller airport and connect. Once you're on a flight and through security, you're pretty much free and clear.

Frankly, I'm surprised that the TSA found it. In my post-9/11 air travels, I've found the TSA screeners less than a confidence-building presence.
