(ii) To defend himself or others against physical assault;

(iii) To prevent serious damage to property;

(iv) To enforce institutional regulations and orders; and

(v) To prevent or quell a riot.

(d) A private-company detention officer who is trained pursuant to the provisions of subsection (a) of this section, shall have the right to carry and use firearms and shall exercise such authority and use deadly force only as a last resort when reasonably necessary to prevent the commission of a violent felony as defined in W.S. 6-1-104(a)(xii) , to prevent the escape of a convicted felon from custody, or to defend the officer or any other person from imminent danger of death or serious bodily injury.

(e) Within three (3) days following an incident involving the use of force against an inmate or another, the employee shall file a written report describing the incident with the administrative staff of the facility and with the contract monitor appointed pursuant to W.S. 7-22-108 .
