The Support Our Law Enforcement and Safe Neighborhoods Act (often referred to simply as Arizona SB 1070) is a legislative act in the U.S. state of Arizona that is the broadest and strictest anti-illegal immigration measure in decades. It has received national and international attention and has spurred considerable controversy.
U.S. federal law requires certain aliens to register with the U.S. government, and to have registration documents in their possession at all times. The Arizona Act additionally makes it a state misdemeanor crime for an alien to be in Arizona without carrying the required documents, bars state or local officials or agencies from restricting enforcement of federal immigration laws, and cracks down on those sheltering, hiring and transporting illegal aliens.
Critics of the legislation say it encourages racial profiling. There have been protests in opposition to the law in over 70 U.S. cities, including boycotts and calls for boycotts of Arizona.
