ICJI 1518 (2010)
Idaho Criminal Jury Instructions
ICJI 1500 BURDEN OF PROOF ON DEFENSES
ICJI 1518 SELF-DEFENSE–REASONABLE FORCE
The kind and degree of force which a person may lawfully use in [self-defense][defense of another] are limited by what a reasonable person in the same situation as such person, seeing what that person sees and knowing what the person knows, then would believe to be necessary. Any use of force beyond that is regarded by the law as excessive. Although a person may believe that the person is acting, and may act, in [self-defense] [defense of another], the person is not justified in using a degree of force clearly in excess of that apparently and reasonably necessary under the existing facts and circumstances.
