As a general rule, deadly force is justified in which of the following cases?

Deadly force is generally justified in the context of an armed robbery because the potential for serious injury or death is significantly heightened when a weapon is involved. The presence of a weapon creates an immediate threat to the safety of individuals involved, including victims and law enforcement personnel. In such situations, the use of deadly force may be seen as necessary to protect oneself or others from imminent harm.

In contrast, unarmed robbery does not present the same immediate threat of lethal force, and scenarios like the observation of an unauthorized entry into a home or the arrest for a misdemeanor typically do not meet the legal standards required for the justification of deadly force. Deadly force is reserved for situations where the threat to life is clear and present, aligning with the principles of self-defense and defense of others.
