§ 28. Decedent's criminal conduct; defendant's self-defense
By statute, it is a defense to a wrongful death action to show, by a preponderance of the evidence, that such action arose from an injury sustained during the commission or attempted commission of a forcible felony by the decedent. Another statute provides immunity from a civil action for the use of deadly force as permitted by specified statutes, unless the person against whom force was used is a law enforcement officer in performance of official duties who acts in the manner described.

§ 508. Generally; nature and foundation of defense
By statute, a person is justified in the use of deadly force if the person reasonably believes that such force is necessary to prevent imminent death or great bodily harm to himself or herself or another or to prevent the imminent commission of a forcible felony. The statute is declaratory of the common law, under which a person attacked under certain circumstances could, to protect himself or herself, take the life of the assailant and excuse himself or herself on the ground of self-defense. The question of justifiable self-defense is ordinarily a question for the jury.
