And TSA's defense of this absurd policy, "In an abundance of caution we require all shoes to be removed and X-rayed to mitigate a variety of threats". What threat, pray tell, do they hope to mitigate that a stroll through the WTMD with shoes on wouldn't catch?

And now that all shoes are being x-rayed, my bet is the % that will get the ETD swab will go down; thus TSA's new policy will actually increase the risk that a shoe bomb could get through.
