Which state statute provides a justification for the use of force to defend oneself, or a third party, from another person's imminent use of unlawful force?

• A. 16-3-21
• B. 17-4-20
• C. 17-4-20(b)
• D. 16-3-20

Answer: (B)

The main idea is that there is a justified use of force when someone defends themselves or another person against an imminent threat of unlawful force. The statute in question recognizes defense of self or defense of another as a lawful justification, so if the defender reasonably believes that force is immediately necessary to avert that threat, they may use reasonable and proportional force. The key elements are: the threat is imminent, the force used is necessary to prevent harm, and the belief in the need to act is reasonable given the circumstances. This also applies to protecting a third party under the same standard. Deadly force is only permitted if there is a reasonable belief that it is necessary to prevent death or serious bodily harm. If these conditions are met, the act is a justified defense, not a crime.
