Interaction, Identity, and Legitimacy

This chapter surveys alternative approaches to crowd dynamics and public order policing, situating the Elaborated Social Identity Model (ESIM) within a wider intellectual landscape. It examines Waddington’s Flashpoints model, Collins’s micro-sociology of violence, video-based studies by Nassauer, Weenink, and van Bruchem et al., Herold’s situational and crime science frameworks, Bürger’s democratic policing principles, Communication Accommodation Theory (CAT), and legitimacy-based perspectives developed by Tyler, Jackson, Tankebe, and Bottoms. Despite their differences, these approaches converge in rejecting classical crowd psychology’s claim that disorder is inevitable. Instead, many stress interaction, meaning, power, and legitimacy as key drivers of behaviour. Flashpoints highlights multi-level conditions for unrest; micro-sociology uncovers the choreography of escalation; crime science provides tools of situational design; CAT exposes the communicative dimension of policing; and legitimacy theory reframes authority as dynamic and negotiated. This chapter acknowledges the empirical and practical contributions of these models, particularly Herold’s operational frameworks, but argues that ESIM offers a uniquely powerful synthesis. By emphasising reciprocal police–crowd influence and legitimacy as the determinant of trajectories, ESIM operates as both explanatory lens and practical guide. This sets the stage for the next chapter, which examines its systematic application in international football policing.
