The right to keep and bear arms is specifically and uniquely tied to the need for a well-regulated militia designed to safeguard the state.
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.
Therefore, membership in same should be mandated prior to purchase.
Disagree,.. Notice in the above that the right to keep and bear arms is invested in "the people", not the militia,... And please understand that the time this was written individuals joining a state militia were typically expected to show with their own weapon... Having citizens with weapons allowed for the easy assembly of state militias, with regulation of the assembled militia being the responsibility of the "free state"...
