"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."
I believe if one were to interpret this amendment, one must begin with the first subordinate clause, "A well regulated Militia,"
In order to well regulate the militia, it makes sense to keep all the guns within our militia. If people want to keep and bear arms, the best way to keep this well regulated is to have the militia hold onto a gun with your name on it. If you really want a gun in your house, well, a tiny lady Wesson should probably do the trick.
