VPC has been playing up this angle lately, "if so few guns are actually used to stop violent crimes, why own one?" To this I say, "So what?" I have a fire extinguisher in my garage. I have never used it to fight a fire. In fact, I'd bet the vast majority of fire extinguishers hanging from walls across America have never been used to fight fires and I'm sure their owners, as am I, are perfectly happy with this. Doesn't mean I'm going to get rid of it.
I like your fire extinguisher analogy. Makes a very good point.
In that case, people defending themselves ought to always kill the perp rather than wounding him or holding him for police. If ya gotta kill ‘em for it to ‘count’, VPC must want more dead perps.
