MISSOURI — Twenty states have castle doctrines while even more have stand-your-ground laws but what constitutes legal self-defense can still vary across these states.
For Missouri, both the castle doctrine and the stand-your-ground law state, the law permits protecting oneself (or a third party, with exceptions) with deadly force should a person feel it is necessary. This “necessary” part, however, is often not made clear and warrants a breakdown of the terminology.
