(a) A law enforcement officer, or any person whom such officer has summoned or directed to assist in making a lawful arrest, need not retreat or desist from efforts to make a lawful arrest because of resistance or threatened resistance to the arrest. Such officer is justified in the use of any force which such officer reasonably believes to be necessary to effect the arrest and the use of any force which such officer reasonably believes to be necessary to defend the officer's self or another from bodily harm while making the arrest. However, such officer is justified in using deadly force only when such officer reasonably believes that such force is necessary to prevent death or great bodily harm to such officer or another person, or when such officer reasonably believes that such force is necessary to prevent the arrest from being defeated by resistance or escape and such officer has probable cause to believe that the person to be arrested has committed or attempted to commit a felony involving death or great bodily harm or is attempting to escape by use of a deadly weapon, or otherwise indicates that such person will endanger human life or inflict great bodily harm unless arrested without delay.
(b) A law enforcement officer making an arrest pursuant to an invalid warrant is justified in the use of any force which such officer would be justified in using if the warrant were valid, unless such officer knows that the warrant is invalid.
