I found an interesting line in the Constitution

[Shankapotomus]

21. As an related aside,

can it be extrapolated that the founders are implying "the right of the people to keep and bear Arms shall not be infringed" was meant to extend only to citizens entering formal militia and military service since you can't have a properly armed military with limited access to weapons or their right to keep and bear Arms infringed. And if you take the whole sentence, "...the right of the people to keep and bear Arms..." is directly attached to the service of "the security of a free State", through a "regulated Militia."

The founders are only mentioning "the right to keep and bear Arms" only in regards to the security of the State, which is the militia's/military's job. They say nothing about keeping and bearing Arms for the use and service of one's personal purposes.
