(a) A peace officer is justified in using that degree of physical force which he reasonably believes to be necessary, upon a person in order:
(1) To make an arrest for a misdemeanor, violation or violation of a criminal ordinance, or to prevent the escape from custody of a person arrested for a misdemeanor, violation or violation of a criminal ordinance, unless the peace officer knows that the arrest is unauthorized; or
(2) To defend himself or a third person from what he reasonably believes to be the use or imminent use of physical force while making or attempting to make an arrest for a misdemeanor, violation or violation of a criminal ordinance, or while preventing or attempting to prevent an escape from custody of a person who has been legally arrested for a misdemeanor, violation or violation of a criminal ordinance.
(b) A peace officer is justified in using deadly physical force upon another person when and to the extent that he reasonably believes it necessary in order:
(1) To make an arrest for a felony or to prevent the escape from custody of a person arrested for a felony, unless the officer knows that the arrest is unauthorized; or
(2) To defend himself or a third person from what he reasonably believes to be the use or imminent use of deadly physical force.
(c) Nothing in subdivision (a)(1), or (b)(1), or (f)(2) constitutes justification for reckless or criminally negligent conduct by a peace officer amounting to an offense against or with respect to persons being arrested or to innocent persons whom he is not seeking to arrest or retain in custody.
(d) A peace officer who is effecting an arrest pursuant to a warrant is justified in using the physical force prescribed in subsections (a) and (b) unless the warrant is invalid and is known by the officer to be invalid.
(e) Except as provided in subsection (f), 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 physical force when and to the extent that he reasonably believes that force to be necessary to carry out the peace officer's direction.
(f) A person who has been directed to assist a peace officer under circumstances specified in subsection (e) may use deadly physical force to effect an arrest or to prevent an escape only when:
