Joe Arpaio

Maricopa County, Arizona, Sheriff Joe Arpaio made a court appearance Tuesday and faced questioning. Arpaio is accused of racial profiling in a civil class-action lawsuit.

At issue is whether Maricopa County Sheriff Joe Arpaio violated the civil rights of Latino citizens and legal U.S. residents. The plaintiffs hope to prove Arpaio's department engaged in systematic racial profiling. The self-proclaimed "Toughest Sheriff in America" says he's cracking down on illegal immigration.
