Knowra Active shooter Active shooter An active shooter is a person actively killing or attempting to kill people in a populated area, usually with a firearm. The term describes an ongoing emergency, not a fixed offender profile.
Mass shooting : A shooting incident in which multiple people are shot or killed, though definitions vary by jurisdiction and dataset. Active-shooter incidents are one kind of shooting emergency, while mass-shooting definitions also include other circumstances.
Run Hide Fight : A public safety framework that presents running, hiding, and fighting as possible responses to an imminent threat. It is a widely used U.S. framework for civilian decisions during an attack.
Terrorism : The use or threat of violence to pursue political, ideological, or religious aims, especially by influencing a wider audience. An active-shooter event may or may not be terrorism; the terms classify different features.
Post-traumatic stress disorder : A mental disorder that can develop after exposure to traumatic events and involves persistent trauma-related symptoms. Survivors and witnesses may experience lasting trauma symptoms after an attack.
Emergency management : The organized coordination of resources to prepare for, respond to, and recover from emergencies. Active-shooter response depends on coordinated action across emergency services and institutions.
Workplace violence prevention : Policies and practices intended to reduce violence risks in workplaces and respond to threats. Employers use prevention plans to address warning signs and prepare for violent emergencies.

Incident Command System : A standardized framework for coordinating personnel and resources during an incident. It gives responding agencies a shared structure for managing a rapidly changing scene.
