The Second Amendment to the United States Constitution undisputedly protects the individual right to own and carry firearms for self-defense, sport, and other uses. But the amendment actually says nothing about guns; it refers to "the right of the people to keep and bear Arms," of which firearms are just one example of what dictionaries define as "a means (such as a weapon) of offense or defense." In Massachusetts, last week, that resulted in a decision by the state's highest court striking down a law against switchblade knives.
