An active shooter is an armed person who has used deadly physical force on other persons and continues to do so while having unrestricted access to additional victims. These situations are dynamic and evolve rapidly, demanding immediate deployment of law enforcement resources to stop the shooting and mitigate harm to innocent victims. In general, how you respond to an active shooter will be dictated by the specific circumstances of the encounter. Be aware that there could be more than one shooter involved in the situation.
