Alaska Criminal Pattern Jury Instructions
AK A.C.P.J.I. 11.81.340 Justification-Use of Force in Def of 3rd Person
A defendant is justified in using force upon another person when and to the extent the defendant reasonably believes it is necessary to defend a third person when, under the circumstances as the defendant reasonably believed them to be, the third person would have been justified in using that degree of force for self-defense.
Unless the state has proven beyond a reasonable doubt that the defendant did not act in defense of a third person, you shall find the defendant not guilty.
