Yes, Castle Doctrine - slightly limited but practically the same also - but again for anyone - not a special privilege of CCW. And that was my point.
So regardless of the State, SD Law is about the same, as it's based in old English common law from many centuries past - as well as many other historical precedents. And just like New York and Florida, none limit rights to SD only to those who have CCWs - and no rights with respect to Defense of Yourself (and the Others clause) exist for a CCW beyond those that everyone has. We're just like everyone else, see? As you yourself indicate, that is a universal fact: CCW has no more privileges than those all citizens have in SD.
