IANAL, but it seems to be pretty well documented and agreed upon internationally that one must produce documents to enter a country. To arrive at a border crossing or port of entry and assert the border agent does not have probable cause to ask for documents just doesn't really seem like a grey area at all. The "freedom auditors" are expressing their rights to doing things that are _defined as legal_ but regularly infringed upon (taking pictures of public property like police station lobbies, post offices and libraries). Refusing to show documents at a port of entry isn't ever defined as legal, AFAICT. Now, this federal ruling is kind of unrelated. It's not about asking for documentation, it's about the ability to search an arrested person's phone after they've been arrested.
