I would make these three observations:
1. A thousand folks would stand up and have a thousand interpretations of the entire Constitution. That’s the sad fact of life over a living document that is continuing on.
2. The original intent was that no state or federal government could walk into your town...task you to hand over your musket to a local arsenal...and release it to you only for hunting purposes. The militia angle was what everyone viewed in the 1770s as part of their local society, and frankly....it worked.
3. If you took most people out of their clean unhostile environment, and put them out into the heartland....towns with crime....rural areas with threatening critters...threats where no cop can react within twenty minutes....then they’d all agree that weapons are a part of life. The mere fact that over 300 million weapons exist in America today....and so few people are killed by them...says a lot. More folks die from overdosing legal and illegal drugs than from gunshot wounds. Hopefully, we grasp the ranking order of the real problems in life.
European Murder Rates Compared to the United States: Demographics vs Guns

In the vast majority of the United States, murder rates are similar to those in Europe. The only place they are significantly higher, are in those places that have a high percentage of the population from a culture that does not exist in significant numbers in Europe.
