In Arkansas, deadly force is justified only to protect human life—your own, your family's, or others'—from imminent death or serious bodily injury.
You may NOT use deadly force solely to protect property. This includes homes, vehicles, belongings, or land.
Arkansas has a Castle Doctrine (no duty to retreat in your home) and Stand Your Ground (no duty to retreat anywhere lawfully present), but both apply only to self-defense against physical threat, not property defense.
Using deadly force against a mere property crime (e.g., car break-in, trespasser fleeing) can lead to manslaughter or murder charges.
