A.R.S. § 13-401: Unavailability of justification defense; justification as defense

A. Even though a person is justified under this chapter in threatening or using physical force or deadly physical force against another, if in doing so such person recklessly injures or kills an innocent third person, the justification afforded by this chapter is unavailable in a prosecution for the reckless injury or killing of the innocent third person.

B. Except as provided in subsection A, justification, as defined in this chapter, is a defense in any prosecution for an offense pursuant to this title.
