City Manager Task Force • Created in April 2010 to address residents’ concerns about Phoenix Police Department interactions with the community • Developed 34 recommendations designed to increase community access to, communication with, and confidence in the Phoenix Police Department • One recommendation called for a pilot program involving the deployment of dashboard cameras 3
Targeted Problems • Violence in general has declined in Phoenix, but domestic violence has remained problematic – Approximately 40,000 incidents of domestic violence are dispatched per year – Domestic violence is one of the top five call types • Shift in relationship with residents – Police community relations are complex in some communities – High-profile events involving police-resident encounters have and continue to occur in these same communities 4
The Technology • Selected Vievu – Self-contained device worn on the torso • Size of a pager – Docking station – Uploaded to Phoenix Police Department servers 5
Quasi-Experimental Design • Repeated measures from the sources below – Police/court data – Administrative records – Officer self-report surveys – Meta-data from cameras – Interviews with officers 6
