30 Patterns of Harm is an independent review by Dr Shereen Daniels, commissioned by the Metropolitan Police Service and recorded on 18 July 2025.

The review examines how the Met’s systems, governance, leadership and culture produce and protect racial harm, and why these patterns persist despite decades of reform efforts. Rather than recounting individual incidents, it focuses on the structural logic — the everyday processes, norms and incentives — that make racial harm a recurring and predictable outcome.

Central to this analysis is the role of anti-Blackness. The report identifies it as the clearest indicator of organisational dysfunction and the sharpest edge of harm within policing. By addressing anti-Blackness directly, the review shows how tackling its causes also helps dismantle the wider systems that enable racial iscrimination against other groups.

This audio recording provides an accessible way to engage with the findings, supporting reflection and helping listeners grasp the depth and intent of the report’s structural approach.
