Use of force in self defense; no duty to retreat.
Wyo. Stat. Ann. § 6-2-602
in effect(a) The use of defensive force whether actual or threatened, is reasonable when it is the defensive force that a reasonable person in like circumstances would judge necessary to prevent an injury or loss, and no more, including deadly force if necessary to prevent imminent death or serious bodily injury to the person employing the deadly force or to another person.

(ii) The person who uses defensive force knew or had reason to believe that an unlawful and forcible entry or unlawful and forcible act was occurring.
(c) The presumption set forth in subsection (b) of this section does not apply if:

(ii) The person sought to be removed is a child or grandchild, or is otherwise in the lawful custody or under the lawful guardianship of, the person against whom the defensive force is used; or
(iii) The person against whom the defensive force is used is a peace officer or employee of the Wyoming department of corrections who enters or attempts to enter another's home or habitation in the performance of his official duties.
(d) A person who unlawfully and by force enters or attempts to enter another's home or habitation is presumed to be doing so with the intent to commit an unlawful act involving force or violence.
(e) A person who is attacked in any place where the person is lawfully present shall not have a duty to retreat before using reasonable defensive force pursuant to subsection (a) of this section provided that he is not the initial aggressor and is not engaged in illegal activity.
(f) A person who uses reasonable defensive force as defined by subsection (a) of this section shall not be criminally prosecuted for that use of reasonable defensive force.
