[Polybius]

Have you a passion for side streets or do you just like changing the subject? Your driver's license is your established permit to use public property and wasn't originally intended nor does it hold a sanctified place now as your primary identity. Your existence is established by your warm body; your right to exist is inherent in the unstated social contract absent demand by authority.

Talk about side streets.....

Security checks at the airport want to try to make it just a little bit harder for terrorists to use "buy and switch" tactics for individuals boarding aircraft. While it is not perfect, it is better than nothing.

If you object to your drivers license being used for such purposes, any valid photo ID such as a passport or a military ID will do just fine.

One last time; no simple, single document is an assurance of true and complete identification.
