What defines an "active shooter scenario"?

An "active shooter scenario" is specifically defined as an incident where an individual is actively engaged in attempting to harm others, typically using a firearm. This definition underscores the immediate danger presented, where the goal of the perpetrator is often to inflict mass casualties within a populated area. Situations that fit this definition are characterized by urgency and the need for a rapid response from law enforcement and emergency services.

The other options—such as a peaceful protest, standard emergency drill, or a natural disaster response—do not align with the nature of an active shooter scenario. A peaceful protest involves individuals exercising their right to assemble without intention to harm, while a standard emergency drill is a planned exercise conducted to prepare for potential emergencies. A natural disaster response pertains to situations caused by environmental factors, which also falls outside the scope of threat posed by an active shooter. Thus, the essence of the active shooter scenario lies in the direct and intentional harm being inflicted on individuals by the perpetrator.
