A well regulated (a word that meant trained when it was written) Militia (all of the people when it was written), being necessary to the security of a free State, the right of the people to keep and bear Arms (a general word for weapons), shall not be infringed (a word that meant hindered or outlawed or otherwise made difficult). The implementation and debate over the Second Amendment has changed radically over the centuries, but we should remember what it meant when it was written so we can understand how we should use it now.
