America’s self-proclaimed toughest sheriff is fast approaching a crossroads where he must decide either to settle claims that his officers racially profiled Latinos in his trademark immigration patrols — and overhaul his practices — or take his chances at trial.

Maricopa County Sheriff Joe Arpaio faces an April 14 deadline for concluding talks with the U.S. Justice Department to settle a wide range of civil rights allegations, including that the sheriff launched some immigration patrols based on letters from people who complained about people with dark skin congregating in a given area or speaking Spanish but never reporting an actual crime. The sheriff has become nationally known for his tough stance against illegal immigration.
