The tremendous degree to which widespread gun ownership makes American homes safer from home invaders is one of the great unreported stories of the American gun-control debate.
The United States suffers from a very high rate of violent crime, compared to most other industrial democracies. Despite recent improvement, the American crime rate is high for crimes that often involve guns (such as murder), and for crimes that rarely involve guns (such as rape, in which only seven percent of criminals use guns).
