In Minnesota the Bill was written to leave the four conditions for deadly force to remain intact. These include retreat not being an option. We have never been required to retreat, but as a part of being an unwilling participant you must not be hanging around when you could be headed elsewhere.
Everyone gets hung up on the extension of the "castle" to other areas. The key is that we don't need a castle, all self defense is based on self. We can't defend something if we are not in danger our ourselves. We are not, and would not be under our proposed, passed and vetoed Bill, allowed to use deadly force unless we are in danger of death or severe bodily harm. The thing the paranoid anti's miss is that we aren't allowed to defend our house, our car, our boat, or our pansies. We are only allowed to defend ourselves and those with us.
