The ACLU's National Prison Project is dedicated to ensuring that our nation’s prisons, jails, juvenile facilities and immigration detention centers comply with the Constitution, federal law, and international human rights principles, and to addressing the crisis of over-incarceration in the U.S. Since 1972, the Project has fought unconstitutional conditions of confinement through public education, advocacy, and successful litigation on behalf of more than 100,000 men, women and children.
