I think this is a point that bears repeating. I have long since lost count of the times I've heard folks say, or post, to the effect of, "The 2A has been the law since 1791." It is often overlooked that the 2A was first incorporated to the States in the last 5 years. In legal timelines, that's very recent. The body of law developing for the 2A is still in its infancy.
