That may be, but it's not the Castle Doctrine. The Castle Doctrine is only that you aren't required to retreat from your home. Stand Your Ground effectively extends the Castle Doctrine to any place you have a right to be. Neither authorizes the use of force, they simply remove the duty to retreat. That doesn't mean there aren't statutes that do authorize force, but that's not the point I was making.
OK let’s go ahead and say this is my fault. As a Colorado resident I had come to think of our “Make My Day Law” (yes that is it’s official name) as being castle doctrine. It’s not castle doctrine, it’s not even referred to as a castle doctrine law. Wikipedia says “The doctrine is not a defined law that can be invoked, but a set of principles which is incorporated in some form in the law of many states.” so therefore my assertions based on Colorado’s “Make My Day Law” are not relevant to “Castle Doctrine”. My idea that someone who has forced entry into your occupied dwelling clearly means you harm and you require no further justification for the use of force is from my having internalized the law which I live under.
