Yes, the other good point: government is not empowered to disarm anyone of anything. Recognizing that governments tend to want to do so, and will twist any granted powers to achieve it (now we have 922(*), with more on the horizon), the Founding Fathers made it clear “not only did we not give any government such a power, we now hereby explicitly forbid any attempt to act that way anyway”.
What they were really doing, as explained in the preamble to the Bill of Rights, was preventing government from using any of the powers it was granted in the original body of the Constitution in ways not amicable to the rights of the people. That preamble is given below:
The conventions of a number of the States having at the time of their adopting the Constitution, expressed a desire, in order to prevent misconstruction or abuse of its powers, that further declaratory and restrictive clauses should be added.
