Another report is soon to be out and the results are as expected:

WASHINGTON -- Screening at U.S. airports is no better now than before the 9/11 terrorist attacks, according to a member of the U.S. House of Representatives who was briefed Friday about an investigation conducted by the Government Accountability Office and one by the Homeland Security Department. 

"A lot of people will be shocked at the billions of dollars we've spent and the results they're going to see," said Rep. John Mica, R-Fla., chairman of the House aviation subcommittee.

Improving the ability to find dangerous materials has been a top goal of the U.S. Transportation Security Administration since it took over the security task at about 450 airports in early 2002. More than 45,000 people were hired.

Oregon Rep. Peter DeFazio, the ranking Democrat on the aviation subcommittee, also was briefed on the two reports, which are to be released within a month.

The TSA, which did not immediately return telephone calls Friday seeking comment, has said in the past that the tests used to measure screener performance are much more rigorous than they were before the Sept. 11 hijackings.

Since then, screeners have been much more aggressive about seizing prohibited items. Each month, screeners confiscate about a half-million objects from passengers, including, on average, 160,000 knives, 2,000 box cutters and 70 guns.

Although they will claim they just need more money for training and better equipment the real problem is that it's an unsolvable problem from this approach.  There are better solutions available but they are politically unacceptable.
