It has dropped out of the news for a while, but now it appears that the fight is continuing. I remember in the 80s we used to make jokes about Soviet citizens being asked "show me your papers" and needing internal passports to travel in their own country. Now we need internal passports to travel in our country. How did this happen? The requirement to show ID for flying on commercial passenger flights started in 1996, in response to the crash of TWA Flight 800. This crash was very likely caused by a mechanical failure. How showing ID to board a plane prevents mechanical failures is left as an exercise to the reader. How mandatory ID even prevents terrorist attacks is also not clear to me; all the 9/11 hijackers had valid government-issued ID. I hope the courts don't wimp out on this fight."
