evidence: The Constitution of the United States was amended to protect the individual rights of citizens to bear arms for security. There is no language in the constitution referring to "hunting" or a "sporting purpose." The reason for the right to keep and bear arms is to protect individual liberty from both foreign and domestic threats; and perhaps most importantly, against a tyrannical government. In a quote attributed to Thomas Jefferson, "The beauty of the Second Amendment is that it will not be needed until they try to take it." [...] But the right guaranteed by the Second Amendment carries with it certain responsibilities, and there are commonsense steps we can take right now to protect our children and keep our communities safe. For instance, we can close the loopholes in the background check system that make it too easy for criminals and other dangerous people to buy guns — an idea that has the support of 90 percent of people in the United States, by the way.
