Policing and collective efficacy: the relative importance of police effectiveness, procedural justice and the obligation to obey police

The role of police in building collective efficacy remains an unanswered question. This paper employs a sample of 4403 people living in 148 neighbourhoods in Brisbane, Australia, to examine the relationship between perceptions of police and collective efficacy. Results indicate that even when controlling for neighbourhood compositional and structural characteristics, trust in police effectiveness and procedural justice are the key variables explaining collective efficacy. Although trust in police effectiveness and procedural justice do not predict neighbourhood differences in collective efficacy, they do explain variations in perceptions of collective efficacy among those residents in a given neighbourhood. These findings reveal that when people trust the police are effective and procedurally just, they are more likely to view their neighbourhoods as collectively efficacious. This research suggests that police can help to encourage collective efficacy, and potentially reduce crime, by communicating their effectiveness and delivering procedural justice to citizens.
