Well, past case law doesn't trump the new current law that addresses those exact cases. With the new laws, if an intruder broke into your house, your perception is that he is about to kill you, especially if he as a gun (loaded or not) and that gives you the right to use deadly force to protect yourself.
Even further, there is a law in Ohio that says if you are injured, maimed or killed during the comission of a crime, you cannot sue.
