Are Post-Sept. 11 Airport Screens Just ‘Security Theater’? – NPR

As any airline passenger can attest, security at the nation’s airports has gotten infinitely more stringent in the eight years since the Sept. 11 attacks.

While the technology to screen passengers has become more advanced and the check-in lines a little shorter, the question of whether flying is terrorism-proof remains.

By now the routine has become mind-numbingly familiar: Travelers take off their shoes and put them in gray plastic containers along with their toiletries. They carry no more than three 3-ounce bottles in a 1-quart plastic bag, remove laptops from cases and so on. It’s a scene played out millions of times a day across the country’s airports.
