You do realise how incredibly fallacious this is, right? The fact that no crime has ever happened to you is completely different from whether or not you pack heat. It's there to make yourself feel better, regardless of whether or not it will end up doing what you intend it to do. Additionally, I seriously doubt even 10% of the people who own firearms for home safety are properly trained in their usage. They're people like you, who simply intend to delude themselves into thinking they are safe just by owning a weapon as possibly deadly as their intruder. Save yourself a little money and possibly your own life via accidental death and invest in a home security system instead.
