Ah! Mea culpa! I made the mistake of assigning a "right" instead of a "power" to a federal facility as I was thinking along the lines of an individual instead of a collective. As an individual I would hope I have the right to demand ID from anyone I chose before I allowed them into my home. As the federal government isn't an individual but is an entity the rules are different?
I've only been in one federal facility (courthouse) since 911 and I had to produce my DL. If I remember correctly I had to produce ID prior to 911 when I went to a national park.
A solution might be to have anyone exiting the bus onto the federal facility produce ID instead of having the blanket polity of all on the bus producing ID.
