some states specifically have a self-defense clause in their state constitutions, but this does not preclude the use of arms for other purposes.
Well, that's a different argument.
However, in law, every word in a statute or constitutional provision is presumed to have purpose, meaning, and effect. And of all of the Amendments contained in the Bill of Rights, the Second is the only one containing an explanatory preamble. The law cannot presume that it's an accident. There must be a reason.
Therefor, the following,
"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."
cannot be deemed the equivalent of:
"The right of the people to keep and bear Arms, shall not be infringed."
There has to be some effect and application to the first part of the sentence. It has to help define the right.
What it suggests to me is that there was a debate about it, which perhaps did not make it into the record (which is true of much of the Constitutional Convention). This was compromise language, and as with other legislation, each side of whatever issues were argued hoped to use the ambiguity to their advantage in future legal or political disputes.
Contrary to popular belief, there was considerable gun regulation at the time. Pennsylvania, for instance, required a loyalty oath prior to gun ownership. Pennsylvania, by the way, as of 1776, also had a state Constitutional provision which mentioned both individual self-defense as well as collective defense. But Madison and the others left the individual element out. Why? It's not clear. But under Common Law principle it must be deemed to have been deliberate.
The initial drafts also included a provision which would have allowed religious pacifists to avoid gun ownership and military service, but that didn't make it into the final draft.
One of the rejected proposals also defined, somewhat, a militia. Nothing ever defined "well regulated."
But nowhere is there proof in the convention discussions that the amendment was intended to protect an individual's right to self-defense. You pretty much have to go to the 9th amendment for that, and ultimately the 14th. And that does not necessarily allow you any weapon you want. We have a Supreme Court case which ruled that the ownership of a sawed-off shotgun is not protected by the amendment because it has no practical use in a well-regulated militia. There is also Circuit Court case which held the same for switchblades. The weapon ownership must have some reasonable relationship to the militia purpose. That was weakened by the latest decision, but not explicitly overturned. Scalia doesn't like to do that, although it appears that nunchuks are protected even if switch blades are not.
