In active shooter situations where ongoing deadly force is reasonably likely to be employed by a suspect and delay in taking law enforcement action could result in injury or death, immediate action by officers at the scene is necessary when such actions are deemed reasonable to prevent further injuries or loss of life.

These documents provide protocols for assessing the threat and immediately responding during active shooter situations to limit serious injury or loss of life. While the term “active shooter” is used throughout, these documents apply to all situations where there is an active assailant or assailants posing an ongoing deadly threat, to include, but not limited to, those from firearms, vehicles, explosives, and knives.
