LONDON — The full-body scanners and intrusive pat-downs that are fast becoming the norm at U.S. airports — just in time for Thanksgiving! — do at least provide the answer to what should be done with Osama bin Laden if he’s ever captured: Rotate him in perpetuity through this security hell, “groin checks” and all.

He’ll crumple fast and wonder that 19 young guys in four planes could so warp the nervous system of the world’s most powerful nation that it has empowered zealous bureaucrats to trample on the liberties for which Americans give thanks this week.

In his stupor, arms raised as his body gets “imaged,” arms outstretched through “enhanced” patting, bin Laden might also wonder at just how stupid it is to assemble huge crowds at the Transportation Security Administration’s airport checkpoints, as if hundreds of people on planes were the only hundreds of people who make plausible targets for terrorists.

It seems Abdulmutallab, a name T.S.A. agents must now memorize, is to blame. Abdulmutallab is the failed Nigerian “underwear bomber” of last Christmas. He joins the failed shoe bomber and failed shampoo-and-bottled-water bombers in a remarkable success: adding another blanket layer of T.S.A checks, including dubious gropes, to the daily humiliations of travelers.
