I don't live in the US or understand all the nuances associated with firearms across there however I do have a few thoughts on the subject.
From Thomas Jefferson all those years ago:
"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."
But the use of muskets and such like in the Revolutionary War is quite different from what is available now such as:

That was the first site I came across.
So would it be prudent to regulate the type of weapons sold as a starting point. Are military type weapons needed to protect you? How many weapons does it take to feel safe?
Some of you have talked about invasion but that is not going to happen and if it did the allies of the US would be there to stand with you. Do you really think that if the US becomes weak due to a massive natural disaster (Yellowstone eruption as an example) the allies would stand by without helping out?
We in the UK had the right to bear arms from the English Bill of Rights 1689 that stated "Subjects which are Protestants may have Arms for their Defense". In 1903 there was greater control brought in for firearms some 200 years or so after the above had been passed. A change in the law was made and that as they say is history. I am not saying there is no gun violence over here but the amount of firearms in circulation per person is regulated and we don't have weapons generally. Do I feel safe? Yes I do but perhaps if things were not regulated and guns were available for everyday use my thoughts might be different.
So going back to 'the right to bear arms' to defend yourselves is part of the US constitution but it is from an age gone by. Most people who I know think of bearing arms is associated with the military which going back to Thomas Jefferson's statement is perhaps what was meant: militia or irregular army that consisted of civilians to bear arms.
Fear, protection and financial elements seem to be the crux of the issues in hand in America today relating firearms and gun control. It appears that you as citizens want to protect yourselves and subsequently fear that without weapons you cannot attain this. With the 2nd amendment it gives you the freedom to exercise the right to bear arms. If gun control is introduced how many people would be out of pocket for the firearms they have purchased if they were forced/requested to hand these in and what would this do for the gun industry nationally?
From the outside looking in the US is at peace and not at war (except war on terror), there is no impending invasion so regulating and or reducing the arms available per person/family could be a first step in gun control. Taking the first steps and making this happen is what will be difficult. There is no easy/quick solution and if the US went down this route I have no doubt it would be painful.
Based upon the US history however the strongest weapon is the will of the people to change things for the better.
