An Active Shooter is a situation where one or more suspects participate in a random or systematic shooting spree and demonstrate intent to continuously harm others. The overriding objective appears to be that of inflicting serious bodily injury/death rather than other criminal conduct. These situations are dynamic and evolve rapidly, demanding immediate deployment of law enforcement resources to stop the shooting and mitigate harm to innocent victims.
Prepare a plan of action for an active shooter in advance. Determine possible escape routes and know where the nearest building exits are.
Information from UCPD’s Your Response to an Active Shooter Brochure (PDF).
If in a hallway, get in a room that is not already secured and secure it.
Unless you are very close to an exit, don’t run through a long hall to get to one, as you may encounter the gunmen or hostage taker.
If in a gym or theater area and the gunmen are not present, move to and out the external exits and move toward any police unit. Drop all bags and keep your hands on your head. Do what the police tell you to do.
Stay alert and look for appropriate cover locations. Hard cover, such as brick walls, large trees, retaining walls, parked vehicles, and any other object that may stop bullets, may be utilized as cover.
If you are trapped with the gunmen, don’t do anything to provoke them.
If they are not shooting, do what they say and don’t move suddenly.
There is no set procedure in this situation. If possible call 911 and talk with a police dispatcher. If you cannot speak, leave the phone line open so the police can hear what is going on.
If they do start shooting people, you need to make a choice: stay still and hope they don’t shoot you, run for an exit while zigzaging, or attack the shooter. If you chose to run, a zigzagging moving target is much harder to hit than a straight runner. Playing dead may also be a consideration.
It is not a recommendation to attack the shooter, but remember that you have a choice to fight when there are no other options. The last thing that the shooter will expect is to be attacked by you.
