WTF do you think “necessary to the security of a free State” means?
It’s really clear in the Virginia Constitution what the point is:
" That a well-regulated militia, composed of the body of the people, trained to arms, is the proper, natural, and safe defence of a free State; that standing armies, in time of peace, should be avoided, as dangerous to liberty; and that in all cases the military should be under strict subordination to, and governed by, the civil power."
