The applicable laws have been posted already on the thread. There are no classified laws related to public transportation, and only anarcho-sheeple would assume otherwise.
By the way, I read what was posted, and I didn't see anything about requiring production of ID. I read how the Undersecretary of Transportation could promulgate regulation....Where are those?
Were they published in the Federal Register? Were they subject to notice and comment?
Good.
FROM THE ARTICLE - This is what we are talking about...
Ann Davis, a spokeswoman for TSA, tacitly acknowledged the strange rabbit hole into which Gilmore has fallen. The Department of Justice, in its first response to Gilmore's suit two years ago, declined to acknowledge whether such an instruction existed. Later, it admitted its existence. Then the government asked a judge to hold a hearing in secret and preclude Gilmore's lawyers from seeing the regulation they sought to challenge, the contents of which seem to be pretty widely known.
If there were no classified laws like you claim then why would the government ask for a secret hearing?
