Is a hard-line sheriff crossing the line when it comes to immigration enforcement?

One of the most controversial figures in the illegal immigration debate is Joe Arpaio, the longtime sheriff of Arizona's Maricopa County, whose aggressive hard line on local crime has received national attention. Has Sheriff Arpaio, who's made the most of federally granted authority to enforce immigration laws, crossed the line when it comes to serving and protecting his community? Some critics have accused him of racial profiling. Our colleagues at EXPOSÉ and local reporters from the East Valley Tribune reveal what Sheriff Arpaio was - and wasn't - doing in the name of law enforcement.

In a special bonus interview, NOW senior correspondent Maria Hinojosa sits down with Joe Arpaio for an intense discussion about the issues and criticism swirling around him.
