On April 23, 2010, Brewer signed the Support Our Law Enforcement and Safe Neighborhoods Act, otherwise known as Arizona SB1070, into law, making it "a state crime for illegal immigrants to not have an alien registration document", and requiring police "to question people about their immigration status if there is reason". It also makes it illegal for people to hire illegal immigrants for day labor or to knowingly transport them. In addition, it provides provisions to allow citizens to file lawsuits against government agencies that hinder enforcement of immigration laws. A follow-on bill, said to address certain "racial profiling" issues with the original bill, was passed by the Arizona legislature just before ending their 2010 session, and was signed by Brewer on April 30, 2010. Signing of the bill has led to massive demonstrations in Arizona, Washington, D.C. and many other cities across the United States, both for and against the legislation.
