Like every other flier, I want to be secure when I travel by air. So I smilingly put up with the feelups and patdowns and every other indignity you’re put through by the TSA at every U.S. airport. At least I know I’m safe from the bad guys. Or am I? The guy who patted me down yesterday apologized for having to do it. He told me that he’ll touch me only with the backs of his hands, assuring me, I suppose, that by using the backs of his hands, he won’t get any thrill out of it
