How many times does it have to be pointed out to you that the AZ law does not require anything above and beyond federal law? That it's the federal law, not the AZ law, which requires resident aliens to carry their documentation at all times? Do you simply not want to know what the truth of the matter is? Have you simply made a decision about this and will not accept that your version of what the law says might be erroneous? It certainly seems that way.2) Enforcing Federal law is one thing, but adding new terms and conditions to Federal law, such as requiring "papers", is not allowed, as that would change the Federal law, thus violating the supremacy clause of Article VI.
Learn what the law says. Then comment. It's the only responsible way to go about it. Anything other than that is only so much uninformed blather.
