Tucson Police Chief On Ariz. Immigration Law

The U.S. Supreme Court heard arguments this week on a controversial Arizona law. The law is intended to deter illegal immigration by requiring local law enforcement to get involved. If police have a reasonable suspicion that someone is in the country illegally, the law requires them to determine immigration status. Melissa Block talks with Tucson Police Chief Roberto Villasenor about the implications for his department should the Supreme Court uphold the law.
