Tomorrow, the Supreme Court will hear arguments over the constitutionally of the “Support Our Law Enforcement and Safe Neighborhoods Act,” also known as SB 1070, Arizona’s draconian and game changing immigration law. It is a big day for the future of immigration law in the United States. The court will consider whether to uphold a lower court’s injunction against the law and will grapple with questions about federal and state power when it comes to immigration policy making.
