It's amazing how many people here think they are Bruce Willis characters.
A criminal comes into your house and you face him with a gun.
You are thinking if I shoot him I get
into a lot of trouble, he's thinking if he shoots you he gets
out of a lot of trouble.
Who do you think wins?
What ever you say about otherwise the statistics prove this the case by a big margin. If yoyu want to protect your home and family, get a dog and an alarm system. Again proven by facts.
But neither a dog or alarm will prove you to be a man.
As for criminals shooting people look at the statistics on non criminals, prior to the ashooting, shooting people. Scary.
