GREAT subject. As you well know, if you ask 10 different persons who enforce and/or interpret the law,you are likely to get 8 different understandings of the "Protection of Persons and Property Act" in S.C., commonly called "The Castle Amendment". The basic concept I teach is if you take a human life over a property crime, you WILL LOSE in a jury trial!
I do not agree that you can do what ever you want to the perp....you may ONLY shoot in self defense to "stop the threat"...emptying a few magazines will probably result in your conviction.
Actually, there are many options a homeowner and/or CWP holder can consider,short of putting himself and heirs in legal jeapordy.
I also recommend against using the "citizens arrest" laws. It did not work for Goober Pyle on "Mayberry" and will probably not work for you.
Most homeowners/citizens are NOT trained in face-to-face combat with a THUG. BTW, I am in total agreement in regards to your thoughts on brandishing.
