'English Disease' and Political Protest: How Social Identity Theory Can Enhance Public Safety at Crowd Events [open pdf - 710KB]
From the Thesis Abstract: "The existing methodologies used by law enforcement to manage crowd events to ensure public safety do not adequately address current protester-on-protester violence. Outdated methodologies, based on classical crowd psychology, may increase the chances of violence between crowd groups. Case study analysis using soccer hooliganism as a proxy for intergroup protest violence demonstrates the relevance of modern crowd psychology in this new protest paradigm. This thesis finds that law enforcement could effectively use social identity theory to understand differing groups' needs and reduce protester-on-protester violence."
