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.
