How violence escalates
Most violent events follow a predictable arc: trigger → escalation → crisis → de-escalation → resolution. The earlier you intervene, the smaller the intervention needed.
Stages of escalation
- · Trigger: insult, frustration, perceived disrespect
- · Anger: rising voice, posture, narrowing attention
- · Crisis: physical threat zone
- · Recovery: dropping arousal, regret possible
- · Stabilization: return to baseline
Warning signs (online & in person)
- · Specific threats with plans
- · Sudden gift-giving or goodbyes (in suicide context)
- · Stockpiling weapons
- · Fixation on previous violence
- · Social withdrawal + grievance ideation
Bystander effect
When many witnesses are present, individual responsibility diffuses — everyone assumes someone else will act. Naming someone directly (‘you, in the red shirt, call 911’) breaks the freeze.
📖 Case study: Columbine retrospective
Post-Columbine analyses revealed warning signs were missed — explicit threats, social isolation, online manifesto. Most school violence is preceded by signals known to peers.
Takeaway: Peers usually know first. Reporting saves lives.
