An active shooter is an individual actively engaged in killing or attempting to kill people in a confined and populated area; in most cases, active shooters use firearm(s) and there is no pattern or method to their selection of victims.
Active shooter situations are unpredictable and evolve quickly. Typically, the immediate deployment of law enforcement is required to stop the shooting and mitigate harm to victims.
Because active shooter situations are often over within 10 to 15 minutes, before law enforcement arrives on the scene, individuals must be prepared both mentally and physically to deal with an active shooter situation.
Good practices for coping with an active shooter situation include:
CALL 911 WHEN IT IS SAFE TO DO SO!
Provide any information you have such as; suspect description, weapons, direction of travel, and anything else you may feel is relative. Reminders of what to do are included in the active shooter checklist.
To get a more in depth understanding of how to deal with this situation please review the active shooter document.
