(Chief Justice John G. Roberts of the Supreme Court of the United States, speaking to U.S. Solicitor General Donald B. Verrilli during today's oral arguments over Arizona's controversial immigration law. The federal government, represented by Verrilli, wants to prevent Arizona from requiring that state law-enforcement officials determine the immigration status of anyone they stop if an officer has reason to suspect that a person may be in the U.S. illegally.)
