Starting in 2005, Arpaio regularly conducted saturation patrols and immigration sweeps, targeting Latino neighborhoods and day laborers. Arpaio also ran many operations targeting businesses employing Latinos, and arresting employees who were unauthorized immigrants for identity theft. According to Arpaio, 100% of the persons arrested for using stolen IDs in 57 raids conducted up until March 2012 were in the country illegally. Until 2011, when a Federal District Court injunction halted the practice, Arpaio maintained an immigrant smuggling squad which illegally stopped cars with Latino drivers or passengers to check their immigration status.
