Note to self: next time I plan to hijack an airplane, leave the box-cutter and underwear bomb at home, and simply hide a gun in my crotch:

An undercover TSA agent was able to get through security at Dallas/Fort Worth International Airport with a handgun during testing of the enhanced-imaging body scanners, according to a high-ranking, inside source at the Transportation Security Administration.

The source said the undercover agent carried a pistol in her undergarments when she put the body scanners to the test. The officer successfully made it through the airport's body scanners every time she tried, the source said.

If only somebody could invent a technology that could detect metal.

Of course, TSA officials insist that there is absolutely nothing wrong with the porno scanners:

TSA agents who spoke to a reporter agreed that the body-imaging scanners are effective — but only if the officers monitoring them are paying attention.

Well, duh-uh. Which is why the best way to smuggle a weapon onboard, as always, remains hiding one in your carry-on luggage.
