MODEL PENAL CODE
In this Article, unless a different meaning plainly is required:
(1) "unlawful force" means force, including confinement, which is employed without the consent of the person against whom it is directed and the employment of which constitutes an offense or actionable tort or would constitute such offense or tort except for a defense (such as the absence of intent, negligence, or mental capacity; duress; youth; or diplomatic status) not amounting to a privilege to use the force. Assent constitutes consent, within the meaning of this Section, whether or not it otherwise is legally effective, except assent to the infliction of death or serious bodily harm.
(2) "deadly force" means force which the actor uses with the purpose of causing or which he knows to create a substantial risk of causing death or serious bodily harm. Purposely firing a firearm in the direction of another person or at a vehicle in which another person is believed to be constitutes deadly force. A threat to cause death or serious bodily harm, by the production of a weapon or otherwise, so long as the actor's purpose is limited to creating an apprehension that he will use deadly force if necessary, does not constitute deadly force;
(3) "dwelling" means any building or structure, though
movable or temporary, or a portion thereof, which is for the time being
the actor's home or place of lodging.
