Police Practices

Every Californian who has an encounter with the police deserves to be treated with dignity and fairness. But too often police officers violate individuals’ constitutional rights. The ACLU of Northern California works to hold law enforcement accountable. We advocate for victims of police misconduct and support reforms that make our communities safer, while also reducing the role of police.
