Body-worn cameras and early intervention systems have become best practices for police departments. A wide body of empirical work has examined body-worn cameras, and there is a growing focus on early intervention systems. However, little research has examined how these mechanisms of accountability influence officer behavior when employed together. Further, little attention has explored whether the effects of body-worn cameras and early intervention systems are stable by officer gender and race, important and largely untested assumptions of each program. To address these gaps, the current study uses longitudinal, administrative data from the Phoenix Police Department to examine patrol officer misconduct between January 1, 2016, and December 31, 2020. Generalized estimating equation models predict seven alleged and sustained misconduct outcomes, including police crime, use of force, harassment/conduct unbecoming, obstruction of justice, neglect of duty, traffic-related, and an overall measure of misconduct. The findings revealed that body-worn camera implementation and activation and early intervention system implementation and referrals individually and in combination were associated with very few substantive changes in officer misconduct. Increases in body-worn camera activation were associated with reductions in sustained police crime (i.e., felonies and misdemeanors), while officers who received an early intervention system referral were more likely to be alleged of police crime in the future. These findings were stable by officer gender and race. Further, past work demonstrates that implementing accountability programs can lead officers to less self-initiated engagement with the public. The current study reaffirmed that body-worn cameras and early intervention systems have unintended effects on officers’ proactive behaviors with unique changes in arrests, citations, and self-initiated incidents across accountability program measures. Given the importance of addressing officer misconduct to build and maintain community trust, the rapid expansion of body-worn cameras and early intervention systems across the United States, and the cost of these systems, it is vital that police departments consider the accountability programs they implement and whether and how these programs influence officer behavior. The current study provides insight into this process in one police agency and offers policy implications and directions for future research.
