The ACLU defends people whose constitutional rights have been violated by the government; this could include a local police department, a state agency, or a public school, for instance.

Please note that the ACLU takes less than 30 cases per year; we take only "test" cases that will affect a broad segment of the population and impact interpretation of the law in years to come.
