I think the founding fathers were well educated, moral, and brilliant men.
Therein lies the problem...
When drafting the Constitution, and the following amendments, they were written as if they would be read, and followed by men of equal intelligence, and morals.
We all know this has not been the case.
In more modern times, people have taken to using their so called "educations" without the corresponding morals.
It's as if an education is nothing more than instructions on "how best to screw over your fellow man for personal gain".
For me... I look at the 2A and see it covers everything... for both the government, and its people.
A well regulated Militia, being necessary to the security of a free State,
the right of the people to keep and bear Arms, shall not be infringed.
The first part... "A well regulated Militia, being necessary to the security of a free State" covers the fact that the state has the right to keep a standing army for it's security. (or call one up)
The second part... "the right of the people to keep and bear Arms, shall not be infringed." covers the fact that the populace may be similarly armed, in case the government goes rouge, and uses its army to subjugate its own people... like they just got done fighting against.
Of note is that they simply state "Arms". In common use meaning "weapons". This is a "gun control" issue in modern times, but its meaning is "ANY TYPE" of weapon. Knife, Sword, Battle Axe, spear, Cannon, Ship of the line, (Battleship)
In short, everything the military had, anyone who could afford it could buy. If we are to go by the actual intent of the 2A, the entire NFA would be nullified, and every weapon would be legal.
Basically, to me this indicates a few things.
1. We can KEEP arms. (of ANY kind)
2. We can BEAR arms. (of ANY kind)
and for us to do either...
3. We can ACCQUIRE arms. (of ANY kind)
Well, we SHOULD be able to anyhow.
