Does Airport Security Really Make Us Safer? | Culture | Vanity Fair: 'Since 9/11, the U.S. has spent more than $1.1 trillion on homeland security.

To a large number of security analysts, this expenditure makes no sense. The vast cost is not worth the infinitesimal benefit. Not only has the actual threat from terror been exaggerated, they say, but the great bulk of the post-9/11 measures to contain it are little more than what Schneier mocks as “security theater”: actions that accomplish nothing but are designed to make the government look like it is on the job. In fact, the continuing expenditure on security may actually have made the United States less safe.'

'Washington assembled a list of potential terror targets that soon swelled to 80,000 places, including local libraries and miniature-golf courses. Accompanying the target list was a watch list of potential suspects that had grown to 1.1 million names by 2008, the most recent date for which figures are available.'

'“The only useful airport security measures since 9/11,” he says, “were locking and reinforcing the cockpit doors, so terrorists can’t break in, positive baggage matching”—ensuring that people can’t put luggage on planes, and then not board them —“and teaching the passengers to fight back. The rest is security theater.”'

'aking off your shoes is next to useless. “It’s like saying, Last time the terrorists wore red shirts, so now we’re going to ban red shirts,” Schneier says. If the T.S.A. focuses on shoes, terrorists will put their explosives elsewhere. “Focusing on specific threats like shoe bombs or snow-globe bombs simply induces the bad guys to do something else. You end up spending a lot on the screening and you haven’t reduced the total threat.”'

'As I waited at security with my fake boarding pass, a T.S.A. agent had darted out and swabbed my hands with a damp, chemically impregnated cloth: a test for explosives. Schneier said, “Apparently the idea is that al-Qaeda has never heard of latex gloves and wiping down with alcohol.” The uselessness of the swab, in his view, exemplifies why Americans should dismiss the T.S.A.’s frequent claim that it relies on “multiple levels” of security. For the extra levels of protection to be useful, each would have to test some factor that is independent of the others. But anyone with the intelligence and savvy to use a laser printer to forge a boarding pass can also pick up a stash of latex gloves to wear while making a bomb. From the standpoint of security, Schneier said, examining boarding passes and swabbing hands are tantamount to performing the same test twice because the person you miss with one test is the same person you'll miss with the other.'

'The full-body-scanner program—some 1,800 scanners operating in every airport in the country—was launched in response to the “underwear bomber” incident on Christmas Day in 2009, when a Nigerian Muslim hid the plastic explosive petn in his briefs and tried to detonate it on a flight from Amsterdam to Detroit. It has an annual price tag of $1.2 billion. The scanners cannot detect petn directly; instead they look for suspicious bulges under clothing. Because petn is a Silly Putty–like material, it can be fashioned into a thin pancake. Taped flat to the stomach, the pancake is invisible to scanning machines. Alternatively, attackers could stick gum-size wads of the explosive in their mouths, then go through security enough times to accumulate the desired amount.'

'Terrorists can so easily switch from target to target and weapon to weapon that focusing on preventing any one type of attack is foolish. Even if the T.S.A. were somehow to make airports impregnable, this would simply divert terrorists to other, less heavily defended targets—shopping malls, movie theaters, churches, stadiums, museums. The terrorist’s goal isn’t to attack an airplane specifically; it’s to sow terror generally. “You spend billions of dollars on the airports and force the terrorists to spend an extra $30 on gas to drive to a hotel or casino and attack it,” Schneier says. “Congratulations!”'
