The paramilitary branch of the Committee for Public Safety was organized by James Stewart Sinclair to protect the Hegemony from the guerilla activities of the Robin Hood Rebellion. Soldiers of the Public Safety Force – the PSF – were first garrisoned on the most distant colonies. During the Second Rebellion, the garrisons were expanded to all of the colony worlds. The advent of the Third Rebellion saw the PSF expanded to include traditional military and fleet operations.
The PSF or “Black and Blues”, as they were aptly named by the media, were authorized to stop anyone, enter any residence or business on the mere suspicion of the presence of a rebel. The media label was based on the color of the PSF uniforms, but it also had a double meaning to the general population of the colonies because of the bruises inflicted by the PSF’s favorite weapon – an old fashioned truncheon.
