The United States is the country with the highest rate of civilian gun ownership in the world. (The second highest is Yemen, where the rate is nevertheless only half that of the U.S.) No civilian population is more powerfully armed.
We have a thing about guns that sets us apart--to our shame and disgrace. The fact is that "guns are involved in a much higher percentage of deaths in the U.S. than just about any other place in the world. . . and guns are more likely than any other weapon to be involved in mass murder in the U.S."
