Well, for one, the ability for the populace to be able to overthrow the government if the need should ever arise.

If that's your best answer, I really think you've just made Bitt's point. If it ever comes to that needing to overthrow the government, I doubt gun laws are going to be much of an issue.

While I think people should have the right to own guns here, I have no problem with restricting what guns people can own, and I certainly have no problem with a waiting period or other measures that promote safe and informed use of firearms.
