2C:3-5. Use of Force for the Protection of Other Persons.

a.  Subject to the provisions of this section and of section 2C:3-9, the use  of force upon or toward the person of another is justifiable to protect a third  person when:

    (1) The actor would be justified under section 2C:3-4 in using such force to  protect himself against the injury he believes to be threatened to the person  whom he seeks to protect;  and

    (2) Under the circumstances as the actor reasonably believes them to be, the  person whom he seeks to protect would be justified in using such protective  force;  and

    (3) The actor reasonably believes that his intervention is necessary for the  protection of such other person.

    b.  Notwithstanding subsection a. of this section:

     (1) When the actor would be obliged under section 2C:3-4 b. (2)(b) to retreat or take other action he is not obliged to do so before using force for the protection of another person, unless he knows that he can thereby secure the complete safety of such other person, and

    (2) When the person whom the actor seeks to protect would be obliged under section 2C:3-4 b. (2)(b) to retreat or take similar action if he knew that he could obtain complete safety by so doing, the actor is obliged to try to cause him to do so before using force in his protection if the actor knows that he can obtain complete safety in that way;  and

    (3) Neither the actor nor the person whom he seeks to protect is obliged to  retreat when in the other's dwelling to any greater extent than in his own.
