Abstract:

Fairness in policing, driven by the effective and transparent investigation and remediation of police misconduct, is vital to maintaining the legitimacy of policing agencies. There are a range of management strategies available to police agencies to prevent serious misconduct. While many of these strategies are well accepted practice, there is limited empirical evidence demonstrating their effectiveness. This research sought to identify the antecedents of serious police misconduct, resulting in dismissal or criminal charge, among a matched sample of 600 officers that had committed serious misconduct, and 600 that had not, across a 13 year-period. A random forest was utilised for analysis, this presentation employs partial dependence plots to explore management strategies which have been identified as either increasing or decreasing risk of serious police misconduct. Predictive features of serious misconduct often did not relate to prior instances of misconduct, for example, secondary employment was an important predictor. In considering features of the policing environment that may be leveraged as protective factors to serious misconduct, three domains were identified. Expedient and opportune complaint resolution processes at a local level, positive behavioural reinforcement, and having a diverse range of career opportunities appear to offer options for prevention of serious misconduct by police officers.
