Papers, please

Meet John Gilmore. He's a 49 year-old philanthropist who lives in San Francisco, California. Through a lot of hard work (and a little luck), John made his fortune as a programmer and entrepreneur in the software industry. Whereas most people in his position would have moved to a tropical island and lived a life of luxury, John chose to use his fortune to protect and defend the US Constitution.

On the 4th of July 2002, John Gilmore, American citizen, decided to take a trip from one part of the United States of America to another. He went to Oakland International Airport -- ticket in hand -- and was told he had to produce his ID if he wanted to travel. He asked to see the law demanding he show his 'papers' and was told after a time that the law was secret and no, he wouldn't be allowed to read it.
