Screeners for the Transportation Security Administration failed to notice fake bombs 60 percent of the time at O'Hare Airport last year. Los Angeles Airport (LAX) was even worse, with bombs passing by screeners 75 percent of the time, according to a classified report obtained by USA Today.
The TSA says the high failure rates stem from "increasingly difficult covert tests that require screeners to find bomb parts the size of a pen cap," the USA Today story said.
But critics argued that terrorists intent on blowing up a plane will use tactics just as sneaky to get explosives past security, and that screeners should be ready.
U.S. Rep. Mark Kirk (R-IL) said he is calling for a conference with federal security officials to discuss training at O'Hare.
