The first Wikipedia page for security theater
was created on December 5, 2004 - so it's not new. But the term deserves wider use, like that in a run-of-the-mill sports story
at Salon (about the Yankees preventing fans from bringing in sun block to protect against a terrorist attack).
You see the same kind of thought with calls to drill for offshore oil or in ANWR. It's the kind of thing that might make people feel better but won't actually do anything to solve the problem.
