The Public Surveillance Unit (or PSU) is the branch of the Justice Department tasked with monitoring the civilian population.
For over twenty years the PSU was led by Judge Jura Edgar, an ambitious (some would say power obsessed) woman. Following Edgar's reassignment as warder of a Cursed Earth Labour Camp the leadership of the PSU was handed over to Judge Rog Niles, formally of the SJS.
After the Statue of Judgement was rebuilt in 2117, the PSU headquarters were moved into it.
In 2134 the Statue was destroyed by East meg Agents From East Meg One agents as part of the Day of Chaos plot. After the Day of Chaos incident the Public Surveillance Unit, the Wally Squad, and the Special Judicial Squad were folded into the new Undercover Operations Division.
