The immigrant smuggling squad that was once a source of political strength for Arpaio is now a legal liability. Hearings will begin Tuesday, April 21, 2015, to determine if Arpaio should be held in contempt for defying a judge’s order to stop his immigration patrols. (AP Photo/Ross D. Franklin, File)
