The Cambridge, MA Police Department (CPD) developed an innovative, data-driven approach to contemporary crime problems, such as gang and gun violence, in the greater Boston area, including the cities of Everett and Somerville. The three agencies established the Regional Analytics for the Safety of Our Residents (RASOR). RASOR was a unique approach to focused deterrence programs that included innovative roles for law enforcement, a collaboration of several jurisdictions, and data-driven approaches and strategies to identify and target offenders. The dedicated staff focused on the implementation design, role of case management, engagement practices, intensive monitoring, and establishing partnerships among various agencies. Many study findings were, however, found to not be statistically significant and revealed the need for future studies on the relationship between dosage and impact.
