There Are Four Primary Categories of Predictive Policing Methods; Each Includes Options to Suit the Capabilities and Requirements of Different Police Departments

• Predictive policing methods fall into four general categories: methods for predicting crimes, methods for predicting offenders, methods for predicting perpetrators' identities, and methods for predicting victims of crime.
• Each category includes options for large departments that handle large amounts of complex data and for smaller departments that require only basic tools to manage and visualize small amounts of geospatial data. Available methods range from basic heuristic techniques to sophisticated, cutting-edge mathematical models.

Predictive Policing Methods Are Not Equivalent to a Crystal Ball, but They Can Enhance Proactive Policing and Improve Intervention Strategies

• Predictive policing methods are not a crystal ball: they cannot foretell the future. They can only identify people and locations at increased risk of crime.
• The operational value of predictive policing tools is in their contribution to broader law enforcement strategies that use the tools' risk assessments to inform resource allocation and problem-solving decisions.
• The collection and use of data on individuals has raised a number of concerns about privacy rights and civil liberties. An understanding of the legal precedent, along with regular audits, public outreach strategies, and greater community involvement and buy-in, have helped police departments address these concerns.
