Public Safety Bureau

The Ministry of Welfare's Public Safety Bureau or the Public Safety Bureau is the main protagonist faction of the science-fiction cop drama anime/manga series ''Psychi-Pass. ''It is the entire political center of Japan and has been tasked with hunting down latent criminals to keep Japanese Society at peace and perfect. Unfortunately however, it is also part of the Sibyl System and serves as its pawn to keep Japan under its grip.

The System
The MWPSB uses a Psycho-Pass to monitor and scan the psychological state of any given person. They then grade the person depending on the rank to see whether or not they are potential latent criminals. If they get a high enough grade, they will either be taken in for rehabilitation or killed on the spot even if they have not commited any crime. However, there is the system in which those who are labeled latent criminals and have high crime proficiency are actually made into MWPSB Inspectors and help them in their search for other latent criminals. This is because of how the criminal inspectors can use their knowledge of criminality to track down and subdue/eliminate other criminals faster and better than ordinary inspectors can.
