I am a fierce defender of the 2nd Amendment yet vehemently  disagree with Joe that there is nothing we mortals can do about violence in society.  While I agree that gun control has gone about as far as it can without crossing into infringing on our rights (actually has gone over the line), I am disappointed with the lack of importance given to mental illness.  Anti-gun groups seem to see this argument as a ruse to avoid new gun laws but they do a real disservice to our country.  The notion that Jesus would never condone a man defending his family, I think, is weak.  As in many things having to do with the Bible, one can find passages for whatever argument they're making.  There is such thing as Natural Law however.  Still derived from God, it tells us that stealing, lying and murder are wrong without any specific quote from Jesus.  Self defense is part of this.
