	The "Support Our Law Enforcement and Safe Neighborhoods Act" (Arizona SB 1070,) was enacted by the Arizona legislature in 2010 as a response to broad public dislike of illegal immigration among Arizona voters, and by a widespread belief that a great deal of crime was being committed by illegal immigrants that persisted despite a scholarly consensus that illegal immigrants commit proportionately fewer crimes than American citizens. Public support for the bill was driven by the March 2010 murder of Arizona rancher Robert Krentz.
