The Pathway to Violence.

Grievance, violent ideation, research and planning the attack, pre-attack preparation, probing and breaches, attack.  

  1. Grievance: An individual may feel wronged due to a real or perceived experience. This feeling may stem from a sense of injustice, victimization, or embarrassment in a relationship, the workplace or life. 
  2. Violent Ideation: The decision to use violence as the answer. While many people have thoughts of violence at times, most will not move toward the pathway to violence. 
  3. Research and Planning the Attack: During this step, an individual may begin thinking about how they would carry out the violence they believe will solve their grievance. They may begin doing research on past attacks, weapons, potential targets, or locations for an attack.
  4. Pre-Attack Preparation: In this phase, the individual is psychologically ready to attack. They may begin preparations, such as collecting weapons, building explosives, target practicing, or purchasing special clothing or equipment.
  5. Probing and Breaches: This step is not always included in the pathway, but it is common to do a “dry run” of an attack. The individual may visit the intended target, look for security cameras, assess police presence, or call in a fake bomb threat or shooting. They may change their plans based on what they learn. 
  6. Attack: The final step on the pathway is carrying out the act of violence.

Note: A person can move up and down this pathway, and there are opportunities at any point to speak up and intercept them before an attack or loss of life.
