Does Airport Security Theatre Really Make Us Safer?

As you stand in endless lines this holiday season, here’s a comforting thought: all those security measures accomplish nothing, at enormous cost. That’s the conclusion of Charles C. Mann, who put the T.S.A. to the test with the help of one of America’s top security experts. Vanity Fair on the security theatre performed by the American TSA:

Terrorists will try to hit the United States again, Schneier says. One has to assume this. 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!”
What the government should be doing is focusing on the terrorists when they are planning their plots. “That’s how the British caught the liquid bombers,” Schneier says. “They never got anywhere near the plane. That’s what you want–not catching them at the last minute as they try to board the flight.”
To walk through an airport with Bruce Schneier is to see how much change a trillion dollars can wreak. So much inconvenience for so little benefit at such a staggering cost. And directed against a threat that, by any objective standard, is quite modest.

Theatre or not, flying through the US sucks. From the Vanity Fair.
