What is the concept of duty to intervene in force situations?

• A. Officers must intercede to stop excessive force or unsafe actions by others to protect people and themselves.
• B. Intervening is optional if the incident seems dangerous.
• C. Only supervisors have a duty to intervene.
• D. Intervention is prohibited in many jurisdictions.

Answer: (A)

Duty to intervene means you must step in when you witness excessive force or unsafe actions by others, in order to stop the dangerous behavior and protect everyone involved, including yourself. This is a standard expectation in training and agency policy because unchecked harm can escalate quickly and create liability for both the officer and the department.

In practice, this means staying aware on scene, using verbal commands, calling for backup, and physically interceding if necessary and safe to do so to halt dangerous actions or excessive force. It also supports accountability—intervening helps ensure that force is appropriate and that colleagues are held to the same standards.

That’s why this choice is the best answer: it accurately describes an obligation to act to prevent harm and safeguard people, not a voluntary option, not limited to supervisors, and not something prohibited by policy.
