An active shooter is defined as an armed person who has used deadly force and continues to do so with unrestricted access to additional victims.

Gaining comprehensive situational awareness is the essential first step in achieving and maintaining security. This will be done by compiling disparate sets of information together into a single, operationally and contextually correct framework - and filling any information gaps that may exist. Furthermore, it is imperative that this integrated common view be observed from the vantage point of a potential aggressor - 'outside-in' rather than 'inside-out' - and that the view be balanced by recognizing the need for free flow through the system of commerce, people, vessels, and vehicles.

This methodology is basically interested in how an aggressor's behavior results from the stimuli both in the environment and within us (internal processes). The aggressor studies, often in minute detail, the behaviors we exhibit while controlling for as many other variables as possible. The results will help us learn a great deal about behaviors, the effect our environment has on us, how we learn new behaviors, and what motivates us to change or remain the same.

This assessment collected and tracked threat situational awareness, threat trending, and risk-reducing mitigation measures in an organized way for a comprehensive view of defenses presented to the aggressor.
