That's a load. It mandates law officers to check anyone requires police to ask for papers from anyone they "suspect" is in the country illegally. The counterpoint to that is, NO law requires ANY American citizen to keep proof of their citizenship on them while exercising their right to traveling freely within the U.S.
Exactly WHO do you think police are most likely to suspect? What Constitutionally legal action should or could they take against an American citizen of Hispanic discent who happens not have proof of citizenship or legal residency on them when asked?
Then, there's the issue that is actually at the heart of the DOJ's suit, whether Arizona's law illegally preempts Federal authority over immigration rights and status. Until that question is answered, not much else matters.
Um. If I am speeding and forgot my drivers license at home what do you think happens when I am pulled over...............
(Hint: You are detained until your identity can be confirmed)
So you end up with 4 scenarios under this law.
1) Produce valid government issued ID.
2) Produce foreign ID and immigration documents (that you are required to carry)
3) Produce foreign ID and no documents. Pretty logical their identity should be further verified.
4) Produce no ID. Detained until ID confirmed.
So you really only end up with a problem in 3/4 and the problem works its self out.
How do you suggest the police confirm your identity if you have no ID?
Hell, police right now check you for warrants even when there is no probable cause that you have a warrant for your arrest. How about that "human rights violation".
