John Gilmore refuses to show his "identity papers"

From the Pittsburgh Post-Gazette.

The regulation that mandates ID at airports is 'Sensitive Security Information.' The law, as it turns out, is unavailable for inspection. …

"Are they just basically saying we just can't travel without identity papers? If that's true, then I'd rather see us go through a real debate that says we want to introduce required identity papers in our society rather than trying to legislate it through the back door through regulations that say there's not any other way to get around," Gilmore said. …

I will show a passport to travel internationally. I'm not willing to show a passport to travel in my own country," Gilmore said. "I used to laugh at countries that had internal passports. And it's happened here and people don't even seem to know about it."
