While there is no proven method to predict when someone might become violent, an individual can exhibit behaviors that might precede violence. The following are warning signs that warrant attention and might require intervention and/or reporting.
- Making threats (direct or indirect) of suicide or hurting one’s self.
- Making implied threats of violence to others.
- Fascination with or asserting ownership of firearms, bombs, or other weapons.
- Preoccupation with incidents of publicized violence.
- Intimidating others.
- Crossing professional and personal boundaries.
- Sudden or erratic agitation with others and/or blaming others when things go wrong.
- Recent and marked decline in academic or job performance.
- Notable changes in personality, mood, or behavior.
- Giving away personal possessions.
- Notable decline in personal hygiene and appearance.
- Abusing alcohol or other drugs.
- Social isolation or alienation.
When attempting to identify warning signs, it is important to consider other factors such as tone of voice and level of familiarity with the person as well as situational contexts. Considering the context in which warning signs occur may help show the level of risk and, in some cases, reveal that more proactive efforts are needed to prevent potential violence.
