Cambridge, Massachusetts
Reducing Crime with Problem-Solving and Predictive Analytics
Project Overview
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.
Methods and Findings
Research Design
Outcome evaluation and process evaluation of the randomized experimental design.
Findings
- No statistically significant differences in time to arraignment between RASOR and control.
- The more time invested by case management and services, the longer the survival time of individuals participating in RASOR (i.e., did not reoffend as quickly as the control group).
