Actually, I do believe the Framers intended that the populace have the means to overthrow the government if it ever gets out of control, or as bad as England was. In the context of history, an armed populace was as powerful as the government at that time.
This is clearly no longer the case, as military training and hardware has evolved beyond anything Benjamin Franklin or Thomas Jefferson could have imagined. Three hicks with AK-47s can't compete with the National Guard for any longer than a few days.
Still, we have seen a massive erosion of our rights with the Patriot Act, and we didn't overthrow the government with guns. Things here are not bad enough to get to that point.
Lastly, my point about the ridiculous argument that because the 2nd Ammendment is in the Constitution, it cannot be changed. I had invited people to comment on he 18th Ammendment, which prohibited alcohol. We decided that was a bad idea, and added the 21st Ammendment, which ended Prohibition.
My point is that the Constitution is a living document, and it can be changed to suit the times. If the 2nd Ammendment is antiquated, let's throw it out. It wouldn't be the first time we've done that. There is a precedent.
