Legal Insurrection:  The U.S. Supreme Court heard oral arguments today about Arizona’s controversial illegal immigratio law, SB 1070.  Based on the initial reports, it appears that the Court may uphold at least one key provision of the law, which allows state law enforcement to inquire about a person’s immigration status.  Even some of the Court’s liberal Justices seemed skeptical about prohibiting state law enforcement from checking the immigration status of a person within the state’s borders.  What remains unclear is how the Court will view the provisions of the law that make it a state crime to violate federal immigration law.
