[QUOTE]Not in Georgia A Castle Doctine State. You break into my home and I will kill you dead unless I see who you are and recogonise you in a few milliseconds. I will not say anything like STOP Get Away From Here that the neighbors will not likely hear. You are shot dead and I will record my 911 call with all of the information to be played at your unlucky survivors court cases. Time for relaxation time.....QUOTE]
One presumes that you would do so if and only if you reasonably believe that the entry is attempted or made for the purpose of assaulting or offering personal violence to any person dwelling or being therein and that such force is necessary to prevent the assault or offer of personal violence or you believe that the entry is made or attempted for the purpose of committing a felony therein and that such force is necessary to prevent the commission of the felony.
It would prove a little tense to have shot someone otherwise simply because you didn't recognize them, wouldn't it?
