What is the term for the expected conduct of an officer in case of witnessing excessive force used by their colleagues?

The term for the expected conduct of an officer when witnessing excessive force used by their colleagues is affirmative duty. In the context of law enforcement, this means that officers have an obligation to take action if they observe another officer using excessive force. This duty is rooted in the principles of accountability and integrity within the police force, reinforcing the idea that all officers are responsible for the actions of their peers, particularly when it comes to protecting the rights and safety of individuals.

Affirmative duty emphasizes that an officer cannot simply stand by or ignore inappropriate conduct; they are required to intervene, report the behavior, and take steps to prevent further harm. This expectation promotes a culture of ethical behavior among officers and enhances public trust in law enforcement agencies.

The other terms do not accurately capture the responsibility imposed on officers in such situations. Discretionary duty suggests that intervention is optional, whereas optional intervention implies a lack of obligation, and involuntary duty is not a recognized legal concept in this context. Thus, the correct terminology highlighting the required intervention in cases of excessive force is affirmative duty.
