Advisory Concerning the Chicago Police Department’s Predictive Risk Models
Chicago Office of Inspector General (OIG)
Chicago has shut down the use of predictive policing models known as the Strategic Subject List (SSL) and Crime and Victimization Risk Model (CVRM). The general areas of concern in the PTV risk model program include: the unreliability of risk scores and tiers; improperly trained sworn personnel; a lack of controls for internal and external access; interventions influenced by PTV risk models which may have attached negative consequences to arrests that did not result in convictions; and a lack of a long-term plan to sustain the PTV models.
