Frequently Asked Questions About Arizona's Racial Profiling Law, S.B. 1070

The U.S. Supreme Court has upheld the most hotly disputed part of Arizona's anti-immigrant law, S.B. 1070, which requires police to determine the immigration status of someone arrested or detained when there is "reasonable suspicion" they are not in the U.S. legally. The ACLU, along with a coalition of civil rights organizations, will continue to challenge the Arizona law on other constitutional grounds.
