Me and Forrest Gump aren't very bright so I gotta ask, how do you “unconstitutionally” seek “to enforce immigration laws.” ???
Immigration is the perview of the Federal Government, and the Feds only per the Constitution. Immigration laws made by a state or city would be unconstitutional. But these aren't immigration laws, they are laws pertaining to business permits and the like, which cities do have jurisdiction over. The ACLU seems to be stretching on this, as it often does.
