A police department in a troubled city implements comprehensive reforms - community policing, de-escalation training, early intervention systems, civilian oversight - and five years later, use of force is down, complaints are down, community trust is up, and the department is cited as national model, proof that change is possible. An officer who grew up in the neighbourhood she patrols knows residents by name, responds to their concerns, prevents violence through relationships, and is beloved figure who represents what policing could be.
