We’re now learning the meaning of a new policy that Americans can’t “willfully” refuse to show ID at airports. The Consumerist has a write-up of one man’s experience with IDless travel. It turns out they do a background check on you using, among other things, your political affiliation.

That’s a nice window onto what identity-based security is all about: giving the government deep access into all of our personal lives. Of course, this type of security is easy to evade, and the 9/11 plot was structured to evade it. Checking ID cannot catch someone who has no history of wrongdoing.

Identity checks at airports require law-abiding American citizens to give up their privacy, including their political affiliations, with essentially no security benefit.
