Some of the most violent attacks in recent times have been perpetrated by offenders who once agitated through a perceived (correctly or incorrectly) slight against them have planned and executed extremely violent attacks in public places or in the homes of their victims. The news reports are filled with familiar sentiments and statements such as “they just snapped” or “I always knew there was something not quite right about them.” Studies show that the instances of a person “snapping” are practically non-existent. In virtually all occasions there were pre-attack behaviours or leakage that had they been addressed would have prevented the violence. Those that describe someone as being not quite right are really saying they have been a witness to behaviour they felt was inappropriate, but they are not able to articulate this or are uncomfortable articulating them at the time. Overall studies have shown that pre-attack indicators can occur for years and months before an act of violence is carried out and if a threat manager intercedes, through the use of an array of strategies the potential offender can be managed off their intended path of violence. This can often be carried out without the need for Police intervention and without overt measures being put in place if carried out correctly. This allows for the safest and most economical outcomes for all parties involved in the vast majority of cases.
