What is an Active Aggressor?

An individual actively engaged in killing, or attempting to kill people in a confined, and populated area.

Be Informed

  • Stay Alert. Always be aware of your environment and any possible dangers.

  • If you see something, say something to local authorities. That includes suspicious packages, people behaving strangely, or someone using strange communications.

  • Observe warning signs. Signs might include unusual or violent communications, expressed anger or intent to cause harm and substance abuse. These warning signs may increase over time.

  • Have an exit plan. Identify exits and areas to hide wherever you go, including work, school and special events.

  • Learn lifesaving skills. Take trainings such as You Are the Help Until Help Arrives and first aid to assist the wounded before help arrives.

Survive DURING

Run to Safety
  • Seek safety. Getting away from the attacker is the top priority.

  • Leave your belongings behind and get away.

  • Call 9-1-1 when you are safe and describe the attacker, location and weapons.


A lockdown is an emergency measure in which a danger is detected inside a building and people are temporarily prevented from entering or leaving.  During a lockdown, the goal is to quickly establish a secure location if you were unable to Run to Safety.  This includes closing and locking doors and windows, closing shades, and turning off lights.  Any fire alarms activated during a lockdown should be treated with suspicious since active shooters have been known to set them off.  Everyone should gather in a safe corner of the room and remain in place until given an All Clear from law enforcement.

Cover and Hide
  • If you can’t evacuate, cover and hide. Find a place to hide out of view of the attacker and if possible, put a solid barrier between yourself and the threat.

  • Lock and block doors, close blinds and turn off lights.

  • Keep silent.

Defend, Disrupt, Fight
  • Fight as a last resort. When you can’t run or cover, attempt to disrupt the attack or disable the attacker.

  • Be aggressive and commit to your actions.

  • Recruit others to ambush the attacker with makeshift weapons like chairs, fire extinguishers, scissors, books, etc.

  • Be prepared to cause severe or lethal injury to the attacker.

Help the Wounded
  • Take care of yourself first and then, if you are able, help the wounded get to safety and provide immediate care. If you are experiencing a medical emergency, call 9-1-1.  Learn how to be the help until help arrives.


When Law Enforcement Arrives
  • Remain calm and follow instructions.

  • Keep hands visible and empty.

  • Report to designated areas to provide information and get help.

  • Follow law enforcement’s instructions and evacuate in the direction they tell you to. 

Monitor Communications
  • Listen to law enforcement’s messages for information about the situation. Share updates with family and friends.


Consider Seeking Professional Help
  • Be mindful of your health. If needed, seek help for you and your family to cope with the trauma.

  • Engage virtually with your community. Know that it’s normal to feel anxious or stressed. Take care of your body and talk to someone if you are feeling upset.
