What is the 'duty to intervene' in a defensive tactics context?

• A. An optional guideline only used in certain agencies.
• B. A requirement to never intervene.
• C. The obligation to intervene if another officer's use of force is inappropriate or unsafe and report it.
• D. A guideline about documenting only after the fact.

Answer: (C)

Duty to intervene means an officer has a responsibility to step in when a fellow officer’s use of force appears inappropriate or unsafe and to report what was observed. This obligation is about preventing harm and ensuring accountability, so intervention should be timely and proportional and, when possible, aimed at de‑escalation or creating space and calling for additional help. It’s not optional nor about never intervening; it’s a policy-driven expectation to act in the moment when safe to do so and then document and report through the proper channels. It’s broader than simply documenting after the fact—the intervention itself is part of maintaining safety and public trust.
