CMLP 2.1_English: Managing Active Shooter and Armed Aggressor Incidents

Active shooter and armed aggressor attacks may target shops, recreational areas, offices, events, rallies and demonstrations, specific people, educational institutions, or government buildings. Attackers may work as individuals, or in groups, using vehicles, knives, guns or explosives to inflict as much damage as possible. They may result from a direct targeted attack or may cause harm through proximity and circumstance. Incidents can be protracted involving hostage-taking and post-incident response will frequently entail dealing with the significant psychological harm to those present or witnessing an attack, as well as mass casualties and the repatriation of serious injured persons and those killed in an attack. The response to an attack is often complex, fast moving and nuanced; requiring a deep appreciation of the risks, and the associated immediate, near and long-term crisis response requirements.
