Jim Harper at Cato-at-Liberty has a great post pointing out the essential truth behind the policy preventing anyone from flying unless an ID is presented.
The first graf:
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-upof one man’s experience with IDless travel. It turns out they do a background check on you using, among other things, your political affiliation.
He goes on to point out the TSA’s “system” is easily subverted by anyone with no history of breaking the law. It does provide a burden on the overwhelming majority of travelers who just want to get from point A to point B. Oh, and it has another effect as well. This time on the civil liberties and right to privacy of the traveler. Two US Constitution granted ideals held near and dear by most Americans.
Identity checks at airports require law-abiding American citizens to give up their privacy, including their political affiliations, with essentially no security benefit.
