Not much point pontificating, so here are some general things I just happened to find interesting while reading around:
1. Not saying anything about the rights and wrongs of the Second Amendment - but it does seem that the original intention for it was indeed that individuals should be entitled to keep weapons. "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." We have our modern sense of militia, but the right to bear arms was central to the road to independence in a different context. The rights of individuals to keep weapons was a right the previous government sought to deny, interestingly it was a right that colonists claimed was based in English law (pre-independence), and ultimately of course those very weapons came in incredibly handy during the victory of the Wars of Independence. It's not surprising then that the framers of the Constitution (who were visionaries beyond question - even if they did borrow from the Declaration of Arbroath EDIT: the amendment was of course, a subsequent amendment to it! END EDIT) sought to give the public the reassurance they desired. That their rights would not be infringed upon by government interference - it was their insurance against oppression. That they had the right to keep weapons, should the need arise to rise up against government interference.
The interesting thing about that, of course, is that Constitutional right to bear arms exists so that public citizens have the means rise up against their own government. To follow that through, the Constitutional right to own a weapon is for the purpose of shooting US soldiers.
Personally I don't think that's why many people who look to the Constitutional right want to keep a gun in the US. I think they hold their armed forces in high regard. Which might undermine their own arguments.
But it does open one intriguing possibility - when it says arms, presumably the public also have a right to keep advances in modern weaponry such as to defeat the military. I kind of like the idea of Bill Gates having his own stealth bomber tucked away for emergencies, or some kind of Dr Evil island in Hawaii.
2. I think the Wikipedia entries on gun control are interesting because you know that every point that's still there has been argued to death - ultimately it must grind down the BS on both sides to some extent.
3. Gun politics (internationally) seem to focus on homicides, do murder rates go up or down? Perhaps the real difference is in accidental shootings and suicides. Doing a Google News search for "accidental shooting" is pretty depressing. And the gun suicide figures (that I've seen anyway) are startling - they looked to be worse than homicides.
