Gaping Holes in Airline Security: Loaded Gun Slips Past TSA Screeners
Secret Tests At LAX, O'Hare, Newark Show TSA Screeners Missed Guns, Bombs

Experts tell ABC News that every year since the September 11 terror attacks, federal agencies have conducted random, covert "red team tests," where undercover agents try to see just how much they can get past security checks at major U.S. airports. And while the Department of Homeland Security closely guards the results as classified, those that have leaked in media reports have been shocking.

According to one report, undercover TSA agents testing security at a Newark airport terminal on one day in 2006 found that TSA screeners failed to detect concealed bombs and guns 20 out of 22 times. A 2007 government audit leaked to USA Today revealed that undercover agents were successful slipping simulated explosives and bomb parts through Los Angeles's LAX airport in 50 out of 70 attempts, and at Chicago's O'Hare airport agents made 75 attempts and succeeded in getting through undetected 45 times.

Sen. Charles Grassley, the Iowa Republican who called on the Government Accountability Office to conduct its own, independent covert tests of airport screening, decried the decision to classify the results as a national security secret.

"Those results aren't going to help terrorists figure out how to better attack us, and they certainly aren't going to give them any more motivation to try than they already have," Grassley said on the senate floor in September. "Keeping the results secret will accomplish one thing, however. It will ensure that the public has no idea how effective our airport screening strategy actually is."

It would appear that the idea is to shut up anyone who points out just how poor a job the TSA is doing.
