The American Civil Liberties Union of Arizona accused the Tucson Police Department of violating protections included in state law, arguing that officers last year conducted an illegal stop of two men sitting in a van just because they were Hispanic. The ACLU is trying to build a case that the Arizona's immigration law, known as SB 1070 and upheld in principle by the U.S. Supreme Court in 2012, is being applied in an unconstitutional manner.
