A Pyscho-Pass is a scan of a person’s mental state by the Sibyl System. It is deeply ingrained in society, being used to determine a person’s career and academic prospect, and even for law enforcement purposes. To overthrow the system, Makishima Shogo invented a helmet that fabricates a low crime coefficient for its wearer. This allows the wearer to trespass and commit crimes without being stopped by security bots and Psycho-Pass scanners. The distribution of this helmet ultimately lead to numerous riots which created chaos for his next plans.

Correction

Um actually … It does not fabricate a Psycho-Pass.

Fabricating a Psycho-Pass is too intensive to be achieved. It instead copies the cleanest Pyscho-Pass from another person within proximity.
