Much of the debate over gun control revolves around interpretations of the Second Amendment to the U.S. Constitution. It reads: *A well-regulated militia being necessary to the security of $a$ free state, the right of the people to keep and bear arms shall not be infringed.* Gun rights advocates tend to focus on the "right of the people to keep and bear arms. " Gun control advocates tend to focus on "a well-regulated militia." Visit a few of the many websites on each side of this issue to find interpretations of the Second Amendment that both support and oppose gun control. Based on what you learn, do you believe that the Second Amendment allows for gun control laws? Defend your opinion.
