Under what circumstance can deadly force be used?

Deadly force can be used in cases of self-defense against serious bodily injury or death. This principle is grounded in the legal standards of use of force that authorize individuals, including peace officers, to protect themselves or others when there is an imminent threat to life or serious injury. The justification for employing deadly force hinges on the necessity of responding to a situation where no viable alternatives exist, and the threat faced is immediate and severe.

In situations of self-defense, it is critical that the individual perceives a real and immediate threat that could result in severe consequences if not addressed. This underlines the importance of assessing the circumstances surrounding the encounter, evaluating the potential for harm, and confirming that the response is proportional to the threat faced. The use of deadly force must always be a last resort, applied only when all other options—such as retreating or de-escalating the situation—are unavailable or ineffective.

Other circumstances leading to the incorrect options generally revolve around the context in which force can be justified. For instance, preventing property damage does not typically warrant the use of deadly force, as property does not equate to the severity of human life. Similarly, apprehending minor offenders does not justify deadly force, as the level of response must match the severity
