Evidence Library

How to use this library (for trainers / investigators)

This library is a reference archive of real-world incidents involving use of force, restraint, and violence. Each case links to open-source footage or reliable reporting and is categorised by variables that matter: environment, weapon type, number of participants, and outcome.

It’s designed as a training and research tool, not entertainment. Use it to identify recurring patterns, tactical failures, and physiological or psychological warning signs that can inform safer, more effective practice.

I’ve provided my own analysis in some cases, but the true purpose here is to provide footage of real events so you can perform your own analysis.

Always follow your agency’s policies, local laws, and use-of-force guidelines in training and operational contexts.

For trainers

  • Use clips to illustrate specific problems: poor control positions, loss of balance, weapon grabs, communication breakdowns, positional asphyxia, and postural collapse.
  • Compare training drills vs. observed behaviour. Ask: did trained techniques appear? If not, why not?
  • Build scenario-based training around real failure points, not idealised sequences.
  • Emphasise decision-making under pressure: what the officer, suspect, or bystanders saw and did in real time.

For investigators / reviewers

  • Treat each case as a behavioural record, not just an outcome. Examine sequence, proximity, resistance level, fatigue, and communication.
  • Cross-reference similar incidents to identify systemic issues: training gaps, policy contradictions, equipment failures, or procedural drift.
  • Note behavioural warning signs: respiratory distress, sudden quietness, postural changes, or agitation escalating to collapse.
  • Use consistent terminology when documenting: position, restraint type, duration, and contributing factors (surface, environment, weapon, etc.).

Caution

This material includes graphic violence and fatal outcomes. View it in the context of professional development and harm reduction.
Do not circulate clips outside education, training or investigative purposes without context. The goal is understanding and prevention, not spectacle.
