Why is the right to bear arms necessary for a free state if not to give the citizenry the ability to overthrow the government? It's not as if indian raids or an invasion from Spain or Britain are causes for concern, nor does the second amendment make up for the lack of a standing army anymore. Overthrowing the government is the only thing left that it's good for, as far as a free state is concerned.
>If the government does not serve the people, the people have an a priori right to reform that government.
What other means of "reform" does the second amendment offer the people, than revolution by force of arms?
