The men that founded our Constitutional Republic were well aware of the failings in fallen human nature. Especially when it comes to those that possess "power". For they knew that "power corrupts", and that "absolute power corrupts absolutely". Which is the precise reason they made a system of "checks and balances" in order to keep "power" in check.
The final "check" in our intended system of government. Is that of the citizens having the right to keep and bear arms for individual and common defense. And this against all enemies; foreign or domestic. And this right was to be free from all government interference. Which is made quit clear by their employing the restriction; "shall not be infringed".
Any type of "control", "restriction" or "regulation" of a Constitutionally secured right. Is clearly a violation of that right that was intended to be secured. And is in all actuality a criminal act perpetrated by those that enacted or uphold it. Which is obviously perversely done in order that the perpetrators would not have to face immediate retribution for their criminal acts.
