The Second Amendment 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." The intent of the 2nd Amendment was to keep the newly formed Congress from taking away the states' rights to have a militia - not to make sure that Frank the wack-a-doo can more efficiently shoot up a campus or office building or that Bubba can turn a duck or deer into confetti.
From Brady Center to Prevent Gun Violence
"The Second Amendment was never intended to provide a constitutional right for individuals to own any and all firearms. In fact, as historian Michael Bellesiles has noted, when the Second Amendment was drafted, gun control laws were the norm in most of the colonies. Contrary to the image portrayed by the gun lobby, guns in those days were rare and expensive. As a result, colonial legislatures from New Hampshire to South Carolina imposed communal storage of firearms and permitted them to be removed only in times of crisis or for "muster day" - the day when the militia would perform its drills. The newly formed states implemented strict laws on gun possession - and historian Saul Cornell has recognized that in most states only the adult, white male population was allowed to own firearms, and even then they were subject to further restriction. In the mid-eighteenth century, Maryland forbade ownership of guns by Catholics and seized the weapons of any eligible male who refused to serve in the militia. In Pennsylvania, over half of the eligible gun-owning population, meaning free, white adult males, were deemed to lack the virtue necessary for the possession of firearms. Again, contrary to the public's understanding, the history is clear that our founding fathers lived during a time of strict gun control."
That is how linguists view the 2nd Amendment. However, the right to bear arms was brought forth by the Founders from England where it was lawful to bear arms to defend your family and property.
James Wilson , who signed the Declaration of Independence, was a lawyer and a major Contributor to the drafting of the Constitution, in the following passage from his Lectures on Law, he equates the passage in the Constitution of the State of Pennsylvania protecting the right "to bear arms in the defense of themselves" with the right of personal defense of one's self or house.
An example discussed by both sides comes from a proposed amendment to the draft of the Constitution proposed by dissenting Pennsylvania delegates to the convention to ratify the US Constitution:
the people have the right to bear arms for the defense of themselves and their own state, or the United States, or for the purpose of killing game
There can be no question that bear arms here is not limited to military activity on the part of a militia.
While I certainly do not want guns of any type falling into the hands of nut jobs, I am no proponent of bigger government and taking away liberties afforded by Americans within the Constitution. Frankly, though, I do not understand the need for these assault weapons or rapid firing firearms? If a gun is truly for protection and one knows how to use it, then why the need for something that fires in rapid succession? Pardon me, I know nothing about guns, I just think of AK47's and what I see in violent movies. Because it's your Constitutional right? It just doesn't make sense to me. If someone feels the need to own that, at that point, society would be out the window and life would be pretty grim.
