On April 23, 2010, Arizona governor Jan Brewer signed into law a discriminatory and un-American law that will require police officers in Arizona to ask people for their papers based only on some undefined "reasonable suspicion" that they are in the country unlawfully. We believe this law, which invites racial profiling in the worst way, is unconstitutional.
