> You don't, at least not in the US. If you took more time to care about the laws you decry, you would know there is no such requirement, unless you have been suspected of a crime by a lawful sworn agent of the state.

If you took the time to read the article I sent you, you would know that CBP asserts that it has the right to get onto any bus at any time and demand to see proof of citizenship for anyone on board.

You can wave the book at me all day long, but what actually matters is how the law is implemented in practice, and it's pretty clear that law enforcement does, in fact, claim the right to stop anyone at any time and ask for ID.
