An active shooter is an individual actively engaged in killing or attempting to kill people, most often in populated areas. In most cases, active shooters use firearms and there is no pattern or method to their selection of victims. In some cases, active shooters use improvised explosive devices to create additional victims and to impede first responders.

When Law Enforcement Arrives
The first law enforcement 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.
