Spiff did actually raise one valid question in his rant: why, if a person is shoe profiled but did not set off the metal detector, should they have to be wanded?

If your shoes meet some profile, fine then, search the shoes. But why does that extend to a wanding of the rest of the person's body, after the offending shoes have been scanned? Especially since the wand and frisk puts the passenger at the highest risk of intentional or unintentional physical abuse, it seems like a purely punitive measure.
