Welcome to the Matrix Demonstration Project (MDP), supported by the Bureau of Justice Assistance. The Matrix Demonstration Project team housed within George Mason University’s Center for Evidence-Based Crime Policy is collaborating with multiple police agencies and international organizations to develop free tools that police officers, analysts, and researchers can use to implement evidence-based policing and translate and institutionalize research findings into daily practice. As part of the project, the MDP team also delivers free workshops, webinars, and symposia to disseminate this information to the law enforcement community.

The MDP is named after the Evidence-Based Policing Matrix because it embodies the spirit of finding innovative ways of translating and institutionalizing research into everyday use by law enforcement. Demonstrations vary widely. For example, we have a “Playbook” that officers can use to implement evidence-based practices in patrol. Our “Case of Places” tool promotes an idea of developing investigations around places, not just people. Our “Building Trust with Communities” demonstration provides three free basic training modules for agencies to learn about procedural justice or implicit bias. The “Hot Spots Lab” provides ideas on how to concentrate police efforts at places. To read articles discussing evidence-based policing and the MDP, click here.

Agencies are encouraged to try these ideas and tools in their own agencies, or to suggest new demonstrations. Demonstration sites are selected based on a strong commitment to the project and regular interactions with the Matrix team. For more information on how to become a demonstration site please contact Professors Cynthia Lum or Christopher Koper (Principal Investigators of the MDP and the Matrix).
