And murder is not only a crime, it is a sin. If that boy dies, the homeowner is liable in a court of law plus a civil case can be brought against him.
Plus, the whole implication that killing another human being has on one's soul cuts deeper into this problem.
I said it before, I am 39 years old. I have lived in some pretty scary places and I have never needed a gun, nor will I ever need one.
This whole thing is a myth.
Poeple tend to think that self defense is not murder. For that matter, the law thinks so too. If someone's trying to kick your door in, it's a fair assumption that they're not selling cookies.
I appreciate your point about it being a sin, and about the affect it may have psychologically in future years, but if someone breaks into my house an I have a choice of Option A (put my hands up and hope) or Option B (do what it takes to protect my wife and kids), I'm sorry, it's no contest.
I admire your conviction that you will never need a gun, and I hope it turns out to be that way for you. If everyone was like you, there would be no need for guns.
