§ 464. Same - Use of force in self-protection.
(a) The use of force upon or toward another person is justifiable when the defendant believes that such force is immediately necessary for the purpose of protecting the defendant against the use of unlawful force by the other person on the present occasion.
(b) Except as otherwise provided in subsections (d) and (e) of this section, a person employing protective force may estimate the necessity thereof under the circumstances as the person believes them to be when the force is used, without retreating, surrendering possession, doing any other act which the person has no legal duty to do or abstaining from any lawful action.
(c) The use of deadly force is justifiable under this section if the defendant believes that such force is necessary to protect the defendant against death, serious physical injury, kidnapping or sexual intercourse compelled by force or threat.
(d) The use of force is not justifiable under this section to resist an arrest which the defendant knows or should know is being made by a peace officer, whether or not the arrest is lawful.
§ 465. Same - Use of force for the protection of other persons.
(a) The use of force upon or toward the person of another is justifiable to protect a third person when:
(1) The defendant would have been justified under § 464 of this title in using such force to protect the defendant against the injury the defendant believes to be threatened to the person whom the defendant seeks to protect; and
(2) Under the circumstances as the defendant believes them to be, the person whom the defendant seeks to protect would have been justified in using such protective force; and
(3) The defendant believes that intervention is necessary for the protection of the other person.
(b) Although the defendant would have been obliged under § 464 of this title to retreat, to surrender the possession of a thing or to comply with a demand before using force in self-protection, there is no obligation to do so before using force for the protection of another person, unless the defendant knows that the defendant can thereby secure the complete safety of the other person.
