The Alabama law chills children’s access to public schools by requiring school officials to verify the immigration status of children and their parents; authorizes police to demand “papers” demonstrating citizenship or immigration status during traffic stops; and criminalizes Alabamians for ordinary, everyday interactions with undocumented individuals. The lawsuit charges that the extreme law endangers public safety, invites the racial profiling of Latinos, Asians and others who appear foreign to an officer and interferes with federal law.
