What constitutes deadly force justification?

Deadly force justification refers to circumstances under which the use of deadly force is deemed lawful and appropriate. The correct answer highlights that behavior which has caused or imminently threatens to cause death or great bodily harm provides the necessary justification for the use of deadly force. This encompasses situations where an individual faces a serious threat to their life or severe injury due to the actions of another person. Law enforcement officers are trained to assess such threats and to react proportionately to ensure their safety and the safety of others.

In contrast, scenarios that involve minor injuries or pose a low risk to life do not meet the threshold for justifying deadly force. Similarly, unprovoked attacks on a person's character are not physical threats, and therefore cannot provide justification for the use of lethal measures. Justification for deadly force is rooted in the necessity to prevent immediate and significant harm, which is precisely why the correct answer emphasizes the imminent threat of death or great bodily harm.
