have you ever fired a gun in the house?

Well, judging by the stories so far, keeping a gun in the house seems to have much more to do with dangerous accidents than killing bad people.

I think few would dispute that having a gun might be nice if someone breaks into your home intent on killing you, but the "liberal" argument is that the harm from the chance of misuse and accidents vastly outweighs the good from crime deterrence.
