To hear the Latino lobby tell it, Arizona’s tough new state law passed to halt illegal immigration into that state, is just short of establishing concentration camps for Mexicans. Mexico’s president, Felipe Calderon claims the law “opens the door to unacceptable discrimination” and many liberal pundits in the US claim the law is unconstitutional because it impinges on the federal responsibility of protecting the US border. Others claim it opens the door to racial profiling, as surely no white American who was stopped by police in Arizona would be asked to provide valid proof of legal residency.
