Use-of-Force Continuum: Indiana Statutory Definitions

(b) A law enforcement officer is justified in using reasonable force if the officer reasonably believes that the force is necessary to effect a lawful arrest. However, an officer is justified in using deadly force only if the officer:
(1) has probable cause to believe that that deadly force is necessary:
(A) to prevent the commission of a forcible felony; or
(B) to effect an arrest of a person who the officer has probable cause to believe poses a threat of serious bodily injury to the officer or a third person; and
(2) has given a warning, if feasible, to the person against whom the deadly force is to be used.
(c) A law enforcement officer making an arrest under an invalid warrant is justified in using force as if the warrant was valid, unless the officer knows that the warrant is invalid.
(d) A law enforcement officer who has an arrested person in custody is justified in using the same force to prevent the escape of the arrested person from custody that the officer would be justified in using if the officer was arresting that person. However, an officer is justified in using deadly force only if the officer:
(1) has probable cause to believe that deadly force is necessary to prevent the escape from custody of a person who the officer has probable cause to believe poses a threat of serious bodily injury to the officer or a third person; and
(2) has given a warning, if feasible, to the person against whom the deadly force is to be used.
(e) A guard or other official in a penal facility or a law enforcement officer is justified in using reasonable force, including deadly force, if the officer has probable cause to believe that the force is necessary to prevent the escape of a person who is detained in the penal facility.
(f) Notwithstanding subsection (b), (d), or (e), a law enforcement officer who is a defendant in a criminal prosecution has the same right as a person who is not a law enforcement officer to assert self-defense under IC 35-41-3-2.
