Good points but what if there is a security risk in granting the injunction?
Same question: What if AZ residents face increased risk of life and property as a result of granting the injunction?
You say that it boils down to a question of law, but what of the crime and violence that would re-establich under a court injunction?
IMO a fair judge will hear the security argument and delay or deny the injunction until the federal government can demonstrate that it will enforce its laws.
AZ should be prepared to show impartial crime statistics that are unequivocally associated with illegal immigration
A security risk in granting the injunction would argue against it. One of the factors is that the public interest must be served by the granting of the injunction. Obviously, a security risk does not further the public interest. The crime statistics you mention would be irrelevant in this case. The only issue before the Court is whether the matters addressed in the Arizona statute are exclusively within the jurisdiction of the Federal government. If so the Arizona is preempted from passing ANY laws on subject.
