This whole issue of definition of self-defense, when push comes to shove, is like the comments made by the Supreme Court when discussing pornagraphy---"when you see it you will know it". Using your own common sense and, being a CCWP holder and having a real interest and commitment to your safety and being CC; you must trust your instincts and you will know when you are in significant and imminent danger and when you can use self defense. If anything, at least in SC, the Castle Doctrine goes even further than my own common sense. I have no intention of going out of my locked bedroom and just looking for, dealing with, and possibly killing someone or getting killed by someone who may be better at this than me, who has forcibly entered my house, and who is stealing things in other rooms (no kids), yet I can do so--legally. That is why I have a cell, why I pay taxes for LEOs, why I have insurance, and why I will stand my ground within my bedroom with a strong position and a big pump shotgun and where I stand a better chance of survival should a perp break thru my bedroom door.
