SB 1070, or the Support Our Law Enforcement and Safe Neighborhoods Act, is a legislative act in the U.S. state of Arizona that was passed in 2010. It is considered the broadest and strictest anti-illegal immigration law in the United States. The law was designed to reduce the size of Arizonas undocumented immigrant population through aggressive state enforcement of federal immigration laws. The law has four main provisions, including police demanding "papers" and investigating immigration status if they suspect a person is undocumented. The law has been controversial and has received international attention, with some viewing it as discriminatory and inviting racial profiling of Latinos and others who may look or sound "foreign". The law has also had significant mental health repercussions on Hispanic adolescents, including those who are legal residents. The Supreme Court has upheld some provisions of the law, including the "show me your papers" provision, which requires individuals to show proof of legal residency if asked by law enforcement. The law has been criticized for its underlying racism and negative implications for communities across the state.
