29. Structural Companion Guide to 30 Patterns of Harm Report

The Structural Companion Guide was developed by Dr Shereen Daniels to accompany 30 Patterns of Harm, an independent review commissioned by the Metropolitan Police Service and published on 18 July 2025.

While 30 Patterns of Harm diagnoses the institutional logics that reproduce racial harm, the Companion Guide provides the scaffolding for what to do next. It sets out the principles, disciplines and structural foundations required to turn insight into practice – helping leaders understand how to rebuild systems that protect people rather than institutions.

The guide is not a checklist or toolkit. It is a framework for reflection, accountability and redesign. It invites the Met to move beyond activity, to align intent with impact, and to create conditions in which anti-racism is embedded within governance, decision-making and everyday leadership practice.

For the full 30 Patterns of Harm report and the Structural Companion Guide, please visit the Metropolitan Police Service website. Both documents should be read together for a complete understanding of the analysis and the route toward meaningful change.
