and(IV) How and when to appropriately and safely transition any person placed in a prone position into a recovery position as soon as practicable.(d) Each entity must review policies and procedures adopted pursuant to subsection (2.7)(b) of this section at least every five years to ensure the policies and procedures are updated to include current best practices.(e) Beginning on or before July 1, 2026, each entity required to adopt policies and procedures pursuant to subsection (2.7)(b) of this section shall implement and train its peace officers on the provisions of the policies and procedures adopted pursuant to subsection (2.7)(b) of this section.(f) The P.O.S.T. board, created in section 24-31-302, shall make its training on the use of the prone position available to all law enforcement agencies in the state.(3) A peace officer is justified in using deadly physical force to make an arrest only when all other means of apprehension are unreasonable given the circumstances and: (a) The arrest is for a felony involving conduct including the use or threatened use of deadly physical force;(b) The suspect poses an immediate threat of death or serious bodily injury to the peace officer or another person;(c) The force employed does not create a substantial risk of injury to other persons.(4) A peace officer shall identify himself or herself as a peace officer and give a clear verbal warning of his or her intent to use firearms or other deadly physical force, with sufficient time for the warning to be observed, unless to do so would unduly place peace officers at risk of injury or would create a risk of death or injury to other persons.(4.5) Notwithstanding any other provision in this section, a peace officer is justified in using deadly force if the peace officer has an objectively reasonable belief that a lesser degree of force is inadequate and the peace officer has objectively reasonable grounds to believe, and does believe, that he or another person is in imminent danger of being killed or of receiving serious bodily injury.(5) Except as provided in subsection (6) of this section, a person who has been directed by a peace officer to assist him to effect an arrest or to prevent an escape from custody is justified in using reasonable and appropriate physical force when and to the extent that he reasonably believes that force to be necessary to carry out the peace officer's direction, unless he knows that the arrest or prospective arrest is not authorized.(6) A person who has been directed to assist a peace officer under circumstances specified in subsection (5) of this section may use deadly physical force to effect an arrest or to prevent an escape only when:(a) He reasonably believes that force to be necessary to defend himself or a third person from what he reasonably believes to be the use or imminent use of deadly physical force; or(b) He is directed or authorized by the peace officer to use deadly physical force and does not know, if that happens to be the case, that the peace officer himself is not authorized to use deadly physical force under the circumstances.(7) A private person acting on his own account is justified in using reasonable and appropriate physical force upon another person when and to the extent that he reasonably believes it necessary to effect an arrest, or to prevent the escape from custody of an arrested person who has committed an offense in his presence;
