Muehler v. Mena

This is a Fourth Amendment challenge brought by a lawful permanent resident who was innocent of any wrongdoing but nonetheless handcuffed and detained by the police for several hours during a police raid of the home where she was living. In the course of her detention, she was also questioned by local law enfocement officers about her immigration status. The ACLU brief refutes the claim that the local police in this case had the legal authority to engage in this immigration questioning.
