While predictive policing has seen widespread use in recent years, the field has lacked a comprehensive resource that assesses the most commonly used tools and helps departments determine which are most appropriate for their jurisdiction. In 2013, Rand Corporation published such a resource: Predictive Policing: The Role of Crime Forecasting in Law Enforcement Operations. This National Institute of Justice (NIJ)-funded research assesses various models of predictive policing, examines promising approaches for acting on predictions, and dispels common myths associated with predictive policing.
