Lawyers for Maricopa County Sheriff Joe Arpaio say they will appeal a federal judge’s ruling that his office violated the constitutional rights of Latinos by targeting them for traffic stops and illegally detaining them based on their race and ethnicity. On Friday, U.S. District Judge Murray Snow ordered the Arizona sheriff’s office to stop using race as a factor in whom it stops. The ruling came as part of a class action lawsuit brought by Latino drivers. Arpaio’s office is facing a separate civil rights lawsuit filed by the U.S. Justice Department.
