Justice, and the enforcement of it, has changed. In the 22nd century, Japan enforces the Sibyl System, an objective means of determining the threat level of each citizen by examining their mental state for signs of criminal intent, known as their Psycho-Pass. Inspectors uphold the law by subjugating, often with lethal force, anyone harboring the slightest ill-will; alongside them are Enforcers, jaded Inspectors that have become latent criminals, granted relative freedom in exchange for carrying out the Inspectors' dirty work.
