Overview of Active Shooter Incidents
What is an Active Shooter?
The Interagency Security Committee defines an active shooter as: "an individual or individuals actively engaged in killing or attempting to kill people in a populated area. In most cases, firearms are the weapon of choice during these incidents, but any weapon (such as a knife, etc.) can be used to harm innocent individuals."²
Active shooting incidents:
- have continued to rise over the past several years
- are often over within 10 to 15 minutes³
- can happen anywhere and anytime
