The American Revolution was fought by minutemen, ready with their guns at a moment’s notice. Early Americans believed that a militia, composed of citizen-soldiers, was a better safeguard of their liberties than a standing or permanent army. Today the militia consists of the National Guard, drilling in state units. Does the Second Amendment protect only the right of the states to have militias, or does it give individuals a right to bear arms for self-defense as well as national defense? That question is at the heart of the debate over the Second Amendment and gun control.
