The failure rates at Los Angeles and Chicago stunned security experts.
"That's a huge cause for concern," said Clark Kent Ervin, the Homeland Security Department's former inspector general. Screeners' inability to find bombs could encourage terrorists to try to bring them on airplanes, Ervin said, and points to the need for more screener training and more powerful checkpoint scanning machines.
In the past year, the TSA has adopted a more aggressive approach in its attempt to keep screeners attentive — the agency runs covert tests every day at every U.S. airport, TSA spokeswoman Ellen Howe said. Screeners who miss detonators, timers, batteries and blocks that resemble plastic explosives get remedial training.

The results of these tests are maddening. If they're going to make our lives miserable by putting in all these extra security procedures, then at least do your damn job!!!

National Health Care would be definitely be like
TSA screening "on steroids"

Wow, brilliant. Doing these sorts of simulations is a *great* idea, but revealing the results to the public is *just plain stupid.*
