Lt. Tao shows Mrs. Phillips and her son Austin pictures from the California Sex Offender Locator. Although the interface shown on camera is not the actual one, the locator is part of sex offender registry operated by the California Attorney General's office under the terms of Megan's Law. California's Megan's Law was named for Megan Kanka, a young girl from New Jersey murdered by a child sex offender living across the street without her family's knowledge. Although controversial, state Megan's Laws have set up registries such as California's to make information about the location of sex offenders previously available only to law enforcement accessible to the public.
