Looking at it in an historical perspective is interesting, but not much more. It's from a time when wars was still fought with muzleloades and daggers. It was also a young and fragile democracy at a time when few countries in rest of the world was democratic and Europe was still burning witches and beheading people for blasphemy(not quite true, but close) so I could see its importance at that particular time in history. We can say that US and most other western countries has evolved quite a bit since then.
If the mechanism to prevent a tyrannical government to take over I doubt that a handful of rednecks (sorry the choice of words)with AR-15 or some 700 bolt actions in 300winmag is gonna have much chance against a A-10 opening fire.
On the other hand I don't think more gun control will stop gun related violence. I think we need to be more careful how we talk about other people. If you talk about your enemies or opponents in a certain way you dehumanize them removing respect of there life's in the process.
I grew up with gun control and it has not hurt me one bit and there is guns in almost every house where I live. Actually it's served me well since it prevented me from blowing too much money on guns.
If you ever want to come to Europe then please stop by, I don't think you will dislike it too much
Edit: can't get my hands on some swift 300wm brass, I'm dying to try it so please bring some.
