Honestly, to me it is one of the best written passages anywhere. My interpretation may not be widely viewed, however here is how I see it:
The "Well regulated militia" part of it was (is) vital in that a militia IS NOT a government agency, it is the assembly of people in common to the defense of a cause or property. At the time it was written certainly the fear was that the King would seize all weapons and if a new government was formed, that such government could readily become corrupt and would then move to do the same thing. The wording of this amendment not only provided, the people with the right to have weapons in their possession and to carry said weapons for defensive needs but also gives the PEOPLE the absolute right to band together, armed in formation of a militia (as opposed to a mob, hence the well regulated) in order to defend a common cause.
That could become very important should say a whole town decide to rise up against the county sheriff. Technically therefore, IMHO, as long as that towns people appointed leadership to direct the effort, this armed group would be a well regulated militia as opposed to a mob and the power of constitutional law would be on their side overriding the authority granted to the sherrif and his deputies under state law. In this matter, constitutional law would mean that the Federal Government should have to back the militia.
It seems like a stretch, but only because we are a fairly sane country, look at many other areas of the world and you can see why this could be an important legal postition.
2A is so much more than saying "you can have guns", if that is all it was meant to say, that is what it would have said, but in reality at the time it was written that was a given since it was the major way of getting food.
The forefathers were not concerned with our right to own guns in general, they never thought that would be challenged except as a sign of tyrany (which perhaps gun control is). Our forefathers concern was with the very existence of freedom and with the ability of US as individuals, to form into the groups, armed and trained to protect it at all costs, from all invaders, including the government they were forming.
Smart men they were!
