California Supreme Court Chief Justice Ronald George, center, Justice Joyce Kennard, left, and Justice Marvin Baxter, right, arrive for oral arguments on the University of California, Berkeley campus in Berkeley, Calif. , Tuesday, Nov. 3, 2009. The California Supreme Court heard arguments about the validity of Jessica's Law, which prohibits sex offenders from living within 2,000 feet of a place where children regularly congregate, like a school or park. The lawsuit was filed by four sex offenders who argue that the residency restrictions violate their constitutional rights and make it nearly impossible to find a place to live.
