The right to bear Arms?
What is the meaning of the Second Amendment of the United States Constitution's Bill of Rights?

Amendment II of the United States Constitution's Bill of Rights declares a well-regulated militia as "being necessary to the security of a free State" and prohibits infringement of "the right of the people to keep and bear arms."
What did the founding fathers mean when they wrote these words and who did it apply too?
The founding fathers knew what a “militia” was militia units fought in most battles in the War of independence, they uses smooth bore and rifled long guns, hand guns, cannon or artiliary, swords, hatchets or tomahawks war clubs and knives. The founding fathers knew what “Arms” where in 1786. Then there where “People” and there were “people” not all had the same rights under the 1786 constitution.
Our society today the closest thing we have to “militia is a “National Guard” that is under control of the State unless activated by the Federal Government, then it is under control of the Federal Government. In 2008 a greater percentage of the “people” living in the United States are “People” than they were in 1786. How do we define the term “Arms” today. In the cold war, the Arms Race with the Soviet Union, included many more weapons than we known to our founding fathers in 1786.
If the second amendment gives people a constitutional right to have hand guns, then to they have that same right to have all weapons we refer to as “Arms” today?
What was included in our founding fathers definition of “Arms”? militia? People?
