Arizona's SB 1070, officially known as the Support Our Law Enforcement and Safe Neighborhoods Act, was enacted in 2010. This law aimed to address illegal immigration by allowing state law enforcement to check the immigration status of individuals during lawful stops. It also made it a state crime to be in Arizona without proper immigration documentation. The law faced significant legal challenges and criticism for potentially encouraging racial profiling. Opponents argued that it could lead to discrimination against Hispanic individuals, regardless of their immigration status. Supporters claimed it was necessary for public safety and to uphold federal immigration laws.
