This chapter considers approaches to embedding principles of procedural justice in policing. Leadership, with strong support from middle managers is clearly essential. One dimension to this is to convey to the workforce the practical benefits that flow from the approach: cooperation and compliance from the public, greater officer safety, fewer complaints from the public. Another important dimension to for leaders to ensure that the ethos within the force is consistent with principles of organisational justice. There must be organisational fairness within police organisations. Organisational fairness is also closely correlated with officers’ sense of self-legitimacy, or their confidence in wielding authority – and self-legitimacy is another precondition for getting the workforce to adopt principles of procedural justice. Training is another strand in the change strategy, and the results of evaluations are positive. Finally the trend towards police professionalisation may prove complementary to, and supportive of, procedural justice approaches to policing.
