Rightist commentators can make several crude comparisons that support the inverse relationship. Generally, there is more gun control in Europe, and less violent crime, than in America. The real question is whether, holding other things constant, adding guns in the hands of law-abiding people reduces crime. Whether between nations within a limited region, or within any single nation, the data from around the world support the inverse relation. A final point remains to be made about the example of Norway, where there is strict gun registration but otherwise lenient laws and relatively high gun ownership.
Crime is low there.
The danger in Norway is that registration makes gun owners easy to find if the government decides to confiscate guns. The 20 th century is filled with cases of governments commencing mass murders soon after confiscating guns.
