What is a notable behavior of active attackers before committing their act?

Active attackers typically engage in thorough planning prior to executing an attack, and this planning phase often occurs significantly in advance, such as at least two days prior. This preparation stage allows them to consider logistics, target selection, weapons acquisition, and potential escape routes, which can indicate a premeditated intent. The level of detailed forethought distinguishes active attackers, as they usually do not act impulsively but rather take time to formulate their approach and to strategize their actions.

Other options do not accurately reflect common behaviors associated with active attackers. For instance, openly discussing their plans would likely diminish the element of surprise and could lead to intervention. Seeking help from authority figures also contrasts with the typical behavior of an attacker, whose motives often involve subverting authority rather than seeking guidance from it. Lastly, trying to gain sympathy from peers may occur in some contexts, but it is not a characteristic behavior that aligns closely with the façade of a planned attack.
