As a girl, I hope I don't hesitate to protect my life or my families. I think it is difficult to give anyone reasonable doubt, whether they mean physical harm. I am seriously considering martial arts (my brother is a teacher in American jujutsu). I think this would give me another option other than immediate deadly force. But if faced with a gun I think you are left no other options than to assume they mean physical harm. *** this is only my opinion right now, it is subject to change and not be used by others***
