Department of Justice

United States Department of Justice was a pre-War department of the United States government. The Department of Justice was a federal executive department responsible for the enforcement of the law and administration of justice in the United States.

Background
Fort Tibbets in Arizona held a small military prison within its boundaries, under the jurisdiction of the Federal Bureau of Prisons. In 1895, the construction of United States Penitentiary Tibbets was authorized through an act of Congress. By 1906, all prisoners had been moved to the new penitentiary, and the Fort Tibbets military prison was returned to the Department of War.

The Bureau of Alcohol, Drugs, Tobacco, Firearms and Lasers, a division of the department, was responsible for the investigation of ownership of illicit objects and substances. The agency also issued licenses to civilians for ownership of advanced weaponry and armor,  and was involved in preventing and apprehending gun rings throughout the nation.

The Federal Bureau of Investigation, another agency of the department active before the Great War, served as the nation's principle federal law enforcement. It was also be involved in the confiscation and destruction of banned material.

During the Great War, the Attorney General was supposed to take shelter in the Congressional Bunker alongside the other members of Congress and the President's Cabinet. However, they were removed from the Cabinet Nuclear Alarm system in questionable circumstances, left to fend for themselves in the face of the Great War.
