And Now… Roving, Random Explosives Checks in U.S. Airports
February 17th, 2010Via: USA Today:
Airport screeners for the first time will begin roving through airports taking chemical swabs from passengers and their bags to check for explosives, the Transportation Security Administration said Tuesday.
The program, already tested at five airports after the attempted Christmas Day bomb plot on a U.S.-bound airliner, begins nationwide in a few weeks, TSA spokeswoman Sterling Payne said. Screeners will push carts with bomb-detection machines around airport gates and checkpoint lines to randomly check passengers’ hands and carry-on bags for explosive residue.

Ultimately you just have to train terrorists in martial arts to crash a plane.
Or train them to use a shovel and a hacksaw to crash a country.
