I am truly surprised that some TSA molesters haven't been beaten into the floor

Or disappeared.  Because they deserve it.
Let's be clear: As I've noted many times before, the TSA is not about security. Beyond the lobbyist and all the others cleaning up from the equipment sales to the TSA, the TSA is about showing the public who's got the power -- and yes, it's the man touching your 12-year-old's genitals.
"Be silent in the face of your oppre- ah, public servants, citizen.  Or else."

Oh, and if you don't quite buy into the notion that the TSA is really about security theater and showing you who has the power, check out something Jonathan Corbett (who showed how easy it is to defeat the scanners) notes about the new more invasive gropedowns:

First, if you're getting a pat-down because you alarmed the body scanner, it's going to be a full-body pat-down despite the fact that the scanners were specifically designed to point out the specific area of the body upon which an item was detected.

Yes, that's right: "despite the fact that the scanners were specifically designed to point out the specific area of the body upon which an item was detected."
Hey, how much fun could they have if they were only allowed to search that area?  The genital(and boob, and butt)-fondling is one of their perks.
