AZ SB1592

Amends Arizona Revised Statutes section 13-410 to require peace officers to reasonably believe deadly force is necessary "based on the totality of the circumstances" before using it.

Defines "imminent" deadly harm as requiring a person to have present ability, opportunity, and apparent intent to immediately cause death or serious physical injury, excluding mere fear of future harm.

Defines "totality of the circumstances" to include all facts known to the peace officer at the time, including the peace officer's own conduct leading up to the use of deadly force.

Removes provision allowing deadly force to suppress riots and modifies language regarding felons to align with revised standards.

Establishes legislative findings that deadly force should only be used when necessary to defend human life, evaluated from perspective of a reasonable officer in the same situation without hindsight, and noting individuals with disabilities are disproportionately affected by police use of force.
