What is the first stage in the five stages of an active shooter incident?

The first stage in the five stages of an active shooter incident is actually the fantasy stage. During this phase, the potential shooter may begin to fantasize about committing a violent act. This stage involves the development of a plan and the conceptualization of the act itself, often reflecting the individual's grievances or motivations. The behaviors associated with this stage can include social isolation, anger, and fixation on past events that drive the individual toward contemplating violence.

Understanding this stage is crucial for prevention efforts, as early intervention can occur if there is recognition of the signs associated with this stage. Identifying the fantasy stage allows law enforcement and community members to take proactive measures before the situation escalates to planning or implementation stages.
