The burden of proof rests on the proponents of the more guns equal more death and fewer guns equal less death mantra, especially since they argue public policy ought to be based on that mantra. To bear that burden would be at the very least require showing that a large number of nations with more guns have more death and that nations that have imposed stringent gun controls have achieved substantial reductions in criminal violence (or suicide). But those correlations are not observed when a large number of nations are compared across the world.
