Scott Willis (Your Views, July 29) should read the text and history of the Second Amendment before offering his “common sense” solutions to criminal gun violence. Contrary to Willis' assertion, the Second Amendment has nothing to do with personal self-protection. It also has nothing to do with hunting or recreational shooting, as President Obama erroneously suggests. The Second Amendment has a singular purpose: to guarantee citizens the right to possess the means to ensure the security of the states. The central government isn't our sole protector and indeed may pose some of the greatest threats to state sovereignty and individual liberty. The Founders considered that free citizens bear full and equal responsibility for securing their freedom. They understood that a government that gives all can take all — including security.
