Preparing for and responding to mass critical incidents includes balancing an effective police response to a mass critical incident while ensuring public safety and maintaining community trust. Protocols emphasize preparedness and risk mitigation during critical incidents and include training in crisis management, communication strategies, collaboration with other emergency response organizations, and post-incident responses to the needs of the community, victims, and officers. Approaches are adjusted based on the particular challenges of a mass critical incident, while ensuring a rapid and coordinated response.
