Mmmm, close. It’s a carry over from (1) slavery and (2) vesting property owners as having ultimate power and rights (for example, initially, owner property owners could vote here). When we abolished slavery, the country recreated its trappings through these knotted and webbed laws. The right to kill to protect self was one that always existed, but added reach when slaves were freed. It is way lethal force in self-defense is more commonly seen (and applied successfully) in southern states. Southern states are, of course, former slave states.
