Somebody's gotta hire these people, I suppose. Even though McDonalds is on a huge hiring spree, even McDonalds requires workers to be intelligent enough to interact with the public with a sense of basic human dignity. Even your basic Wal-Mart greeter must demonstrate some fundamental understanding of keeping customers happy. But for those who utterly fail to value the dignity of other human beings or are too mentally incapacitated to offer anything of value to society, the TSA is always hiring. (They'll even give you a neat looking badge!)
By the way, if you really want to know how illegal the TSA's actions really are, try this little experiment this coming Halloween (not really, but I'm making a point using satire): Dress up as a TSA agent and then run around your neighborhood fondling little kids. It won't take long before somebody calls the cops and has you arrested. And that's what we should be doing right now to the costume-wearing TSA agents in the airports, too.
