According to this 2016 story in the Washington Post, only one-third to two-fifths of American households include someone who owns a gun, despite the fact that there are more guns than people in this country. Gun owning households typically own four or five guns, and some own as many as twenty or thirty. Since 1986, it has been illegal to buy a fully automatic weapon [one that keeps firing as long as you keep pressing the trigger], but it is legal to buy a kit that converts a semi-automatic weapon [one that fires again and again without reloading as you press the trigger again and again] to an automatic weapon, and there are YouTube videos showing you how to make the conversion.
America is not a nation. It is a dystopian war zone.
