How do most active attackers prepare prior to their incident?

Active attackers typically prepare prior to their incidents by developing tactical plans. This preparation involves careful consideration of their objectives, timing, and methods of execution. Developing a tactical plan allows attackers to outline the steps they intend to take to achieve their goals, including the selection of a location, the identification of potential targets, and decision-making regarding when and how to act.

While purchasing new weapons, avoiding public spaces, or constructing escape routes may be part of a broader strategy for some individuals, the core of most attackers' preparations revolves around having a clear and thought-out plan. This planning phase is crucial, as it provides structure and organization to their intentions, significantly impacting the effectiveness and execution of their actions during the incident.
