Active Shooter

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 firearms(s) and there is no pattern or method to their selection of victim.

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 1- 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.

Responding to an active shooter

MSM Public Safety Personnel actively train in responding to violence on the campus including the response to active shooters. In addition, drills are regularly conducted on the main campus. Your part in preparing for this type of incident, on or off campus, is to watch the video “” and to read and understand the information listed below. 

How to Respond when an Active Shooter is in Your Vicinity

Quickly determine the most reasonable way to protect your own life. Remember that customers and clients are likely to follow the lead of employees and managers during an active shooter situation.

Evacuate (RUN)

If there is an accessible escape path, attempt to evacuate the premises. Be sure to:

  • Have an escape route and plan in mind (try to learn at least two ways of evacuating an area)
  • Evacuate regardless of whether others agree to follow
  • Leave your belongings behind
  • Help others escape, if possible
  • Prevent individuals from entering an area where the active shooter may be
  • Keep your hands visible
  • Follow the instructions of any police officers
  • Do not attempt to move wounded people
  • Call 911 when you are safe

Hide out (HIDE)

If evacuation is not possible, find a place to hide where the active shooter is less likely to find you.

Your hiding place should:

  • Be out of the active shooter’s view
  • Provide protection if shots are fired in your direction (i.e., an office with a closed and locked door)
  • Not trap you or restrict your options for movement

To prevent an active shooter from entering your hiding place:

  • Lock the door
  • Blockade the door with heavy furniture

If the active shooter is nearby:

  • Lock the door
  • Silence your cell phone and/or pager
  • Turn off any source of noise (i.e., radios, televisions)
  • Hide behind large items (i.e., cabinets, desks)
  • Remain quiet

 If evacuation and hiding out are not possible:

  • Remain calm
  • Dial 911, if possible, to alert police to the active shooter’s location
  • If you cannot speak, leave the line open and allow the dispatcher to listen

Take action against the active shooter (FIGHT)

As a last resort, and only when your life is in imminent danger, attempt to disrupt and/or incapacitate the active shooter by:

  • Acting as aggressively as possible against him/her
  • Throwing items and using ANYTHING and EVERYTHING as a WEAPON
  • Yelling
  • Committing to your actions 

How to Respond when Law Enforcement Arrives

Law enforcement’s purpose is to stop the active shooter as soon as possible. Officers will proceed directly to the area in which the last shots were heard.

  • Ƶ Officers will immediately respond to the threat
  • Officers from other agencies will also respond, you may not recognize the responding officers
  • Officers may wear regular patrol uniforms or external bulletproof vests, Kevlar helmets, and other tactical equipment
  • Officers may be armed with rifles, shotguns, handguns
  • Officers may use tasers, pepper spray or tear gas to control the situation
  • Officers may shout commands, and may push individuals to the ground for their safety

How to react when law enforcement arrives:

  • Remain calm, and follow officers’ instructions
  • Put down any items in your hands (i.e., bags, jackets)
  • Immediately raise hands and spread fingers
  • Keep hands visible at all times
  • Avoid making quick movements toward officers such as holding on to them for safety
  • Avoid pointing, screaming and/or yelling
  • Do not stop to ask officers for help or direction when evacuating, just proceed in the direction from which officers are entering the premises

Information to provide to law enforcement or 911 operators:

  • Location of the active shooter
  • Number of shooters, if more than one
  • Physical description of shooter/s
  • Number and type of weapons held by the shooter/s
  • Number of potential victims at the location

 The first officers to arrive to the scene will not stop to help injured persons. Expect rescue teams comprised of additional officers and emergency medical personnel to follow the initial officers. These rescue teams will treat and remove any injured persons. They may also call upon able-bodied individuals to assist in removing the wounded from the premises.

Once you have reached a safe location or an assembly point, you will likely be held in that area by law enforcement until the situation is under control, and all witnesses have been identified and questioned. Do not leave until law enforcement authorities have instructed you to do so.
