I’ve got a piece in today’s New York Post that points out some inconvenient truths about the body scanners now installed at airports across the country. Building on Jim Harper’s excellent post, body scanners are not being installed because of a well-reasoned risk analysis.

As Timothy Carney pointed out in the Washington Examiner, this is a sop to the companies that make the body scanners. The machines don’t work as well as advertised – a March GAO Report determined that it is not certain the technology would have found Farouk Abdulmutallab’s suspicious package, and that a cost-benefit analysis needed to be conducted before spending $340 million each year to run the labor-intensive equipment.

The same report found that cargo screening was a weak spot that ought to be addressed, but it took terrorist cargo bomb plots to get the TSA to momentarily escape the clutches of regulatory capture and tend to this threat. The British have been much more candid about the limitations of this technology as applied to low-density explosives, noting that the scanners probably wouldn’t have stopped the 2006 liquid bomb plot at Heathrow.

Of course, you can always opt out of the body scanners in favor of a groping on par with the one that motivated my colleague Penn Jillette to report his sexual assault to the police.

You could opt out entirely. TSA Director John Pistole says you won’t fly, but if you publicize your objections, the TSA may try to fine you $11,000.

Keep a stiff upper lip. I’m sure that this will all be much smoother and less invasive when TSA screeners unionize.
