Federal Bureau of Prisons The Federal Bureau of Prisons (BOP) is a United States federal law enforcement agency.

The system handles inmates who have violated, or are accused of violating, federal law. The BOP also holds inmates who have committed felonies in Washington, D.C.
Public defender (United States) In US civil cases (e.g., personal injury or a landlord-tenant dispute), public defenders may be appointed in civil cases that are quasi-criminal in nature (e.g., removal of children from parents and civil commitments for alleged sexually violent predators)[29] or in highly unusual situations where the civil proceedings may be highly connected to criminal proceedings;[30] otherwise indigent litigants are referred to a legal aid office.
