No doubt, travelers will rejoice at the "convenience" of being allowed to keep their shoes on once the TSA develops a "Shoe Scanning Device." But will your bunion be an anomaly, triggering a close-up inspection of your foot?
Terrorists have already moved on - as if they ever were seriously trying to implement shoe-bombs. They won't use a shoe bomb and they won't target an airplane. It will be something else and we'll gladly give up our rights to prevent the last attack next time, too. (If that last sentence didn't make any sense, it's because the TSA is confused, not my English.)
