Sec. 94-2. Use of physical force in defense of person.
(a) Except as otherwise provided by law, a person is justified in using physical force upon another person in order to defend that person's self or a third person from what the person charged reasonably believed to be the use or imminent use of unlawful physical force by the other person, and the person charged used a degree of force which was reasonable and appropriate.
(b) The defense described in subsection (a) of this section shall not include force used in retaliation.
(c) Retaliations means:
(1) The use or threatened use of physical force after the other party has withdrawn from the encounter and effectively communicated to the person who is retaliating that intent to withdraw, by words or actions;
(2) The use of a degree of force which a reasonable person would not believe necessary for the purpose of defense against another person under the same or similar circumstance; or
(3) The use of force which is not intended for self-defense, but to return an injury or wrong to another person who has used physical force. (Code 1979, § 27-6)
