Beyond the Business Case: Reframing EDI as Legitimacy Infrastructure in Policing

This article argues that police services should not defend Equity, Diversity, and Inclusion (EDI) primarily through the private-sector “business case”. Although claims about performance, efficiency, and reputation may have value, they are too fragile to sustain inclusion when politics, budgets, or public opinion shift. The article instead develops the concept of legitimacy infrastructure: the internal systems, behaviours, and leadership practices through which police services sustain public confidence, officer self-legitimacy, and policing by consent. It grounds this argument in three converging bodies of published evidence. First, quasi-experimental studies of police reform in England and Wales show that increases in workforce representativeness were followed by reductions in misconduct, disproportionality in stop and search, and recorded crime (Hong, 2016, 2017a, 2017b). Second, organisational justice research demonstrates that officers who experience fairness inside their organisation are more likely to endorse democratic policing and less likely to engage in misconduct (Wolfe and Piquero, 2011; Bradford and Quinton, 2014; Trinkner et al., 2016). Third, counter-terrorism studies show that procedural fairness, not enforcement capability, is the strongest predictor of community cooperation and intelligence sharing (Tyler et al., 2010; Huq et al., 2011; Madon et al., 2017). The article translates this evidence into a governance agenda for police leaders, including legitimacy impact assessments, legitimacy “near-miss” reviews, inclusion stress-testing, and a twin-track dashboard that combines experience metrics with community confidence indicators. To test the diagnostic value of that dashboard, and to test whether the underlying pattern generalises beyond one country, the article reconstructs it using published data on the Metropolitan Police and compares the result against national polling and federal civil rights findings from the United States. In both countries, general confidence measures understate persistent gaps that more specific indicators, such as trust, treatment fairness, and stop and search exposure, reveal. For police leaders and policy makers, the practical implication is that no single headline metric, in any jurisdiction, is a reliable guide to whether inclusion and internal fairness are improving, and that the paired-indicator approach set out here is both low-cost and buildable from data already collected.
