Supporters and opponents of Alabama's anti-illegal immigration law are squaring off. The U.S. Civil Rights Commission was holding a field hearing in Birmingham on Friday. The panel is compiling information for a report on state laws designed to enforce immigration laws. Opponents say immigrants are being hurt by Alabama's law. But the law's chief sponsor, state Sen. Scott Beason (R-Gardendale), says that's not true. "The real victims in the illegal immigration debate are American citizens. Those are the people that have been deprived of their jobs, and those are the people that pay the taxes that pay for benefits that go to people that aren't supposed to be in the country." At one point a protester attempted to disrupt the hearing by waving a banner that read "undocumented," while screaming in Spanish. The demonstrator was removed.
