A knife is quiet, you could probably kill more people with knives, a gun is loud and everyone nearby will hear it, probably what a crazy shooter would want is to strike fear into victims.
> You're more likely to use the gun to kill yourself or a family member than you are to use it to kill an intruder.
Since neither of those two are a viable option for myself, I'd rather have a gun, and only ever shoot it at a range than not have one and watch the worse possible scenario unfold before me.
> Killing someone who breaks into your home is most likely an overreaction in any case. The chances are very low that they've broken in with the intention of harming you rather than merely stealing something.
I don't know that, and I don't have to kill them if I pull a gun on them unless my life is in immediate danger. There's cases where a mother held the intruder at gun point until cops showed up to make an arrest.
