Excellent point. lets get rid of all guns. That will stop violence.
I don't think anybody is saying that, other than in your head. The study I linked only shows that keeping your gun at home makes you much less likely to get killed by gunfire. The odds of that happening are ridiculously low, regardless.
No. No one is saying that. But people ARE saying guns like AR-15's need to be eliminated. I posed the question, "What would that accomplish?" We have an ignorant white supremacist killing what he perceives as Muslims... where does gun control factor in there? If he didn't have a hand gun - what would he have used? His car? A bomb? A knife?
As for your study - I didn't even read it. Even IF it had taken into account how many crimes are stopped because of legal carry, which I doubt it did, scientific data is always biased when it is reported. I can pull studies night and day showing where carrying a gun makes you safer - just as you can pull studies night and day showing guns are hazardous.
So it all comes down to this statement, which was one of the first statements I posted: If your concern is for the safety of society, your time would be better spent not taking away guns, but creating a world where guns are not needed.
