I guess I'm in the minority with my opinion, but YES, I'd shoot if I felt my life or the life of a family member was in danger! That is the only reason I carry a firearm--to protect myself and my family!
I don't care if the threat is black, white, yellow, purple, male, female, 8 or 80--if they shoot you, you are just as dead regardless of their age, race, or sex!!!! So if I felt my life was in danger, why in the heck wouldn't I shoot?
I didn't spend the time and money to take classes and go to the range and practice and develop my skills to get shot by some punk kid with a gun who isn't old enough to realize the consequences of his actions! I'd be dead and he'd spend till his 18th birthday in a juvenile detention facility, have his record sealed by a judge, and go on with his life. I'd be dead and my family would be without a father/husband/grandfather.
Would I feel bad about killing a kid? Yah, probably--but not as bad as I'd feel if the kid killed my wife, and not as bad as my wife would feel if the kid killed me! If I wouldn't use my gun to protect myself and/or a family member, I might as well sell it or lock it up and not bother carrying! I made the decision BEFORE I started carrying that I WOULD use it to protect myself and/or my wife or a family member. I made that decision BEFORE I took the concealed carry class. And it had nothing to do with checking the age, race, sex, etc. of an assailant!
