Attorney Tom Liddy, who is representing Maricopa County Sheriff Joe Arpaio and the sheriff's office, and another member of his legal team arrive at the Sandra Day O'Connor United States Courthouse for Arpaio's civil rights trial in Phoenix, Arizona, August 2, 2012. Arpaio, who styles himself "America's toughest sheriff," is on trial in U.S. District Court in Phoenix in a class-action lawsuit that will test whether police can target illegal immigrants without racially profiling Hispanic citizens and legal residents.
