Critical Incident Management

Investigation — Authorised Professional Practice

All topics

Summary

Critical incident management (CIM) is a practice that originated from the public inquiry into the murder of Stephen Lawrence in 1993. It emphasizes risk management and involves principles that highlight that critical incidents are often the result of multiple factors, rather than a single action or inaction. Various types of incidents can become critical, usually categorized as high profile or serious, though not exclusively related to homicide. The police have a duty to effectively respond to every incident, ensuring appropriate actions are taken to maintain public confidence in policing, which is crucial for community trust and safety.
