I should withdraw my original comment. I spent a while re-researching the original intent, the Heller case and some of the subsequent cases to its current interpretation.

I believe it was originally intended to prevent federal overreach. Except that when there was a belief by some people that that had happened and there was an invasion of the capital. That confused me. I don’t know what the rights and wrongs were - apparently the alleged overreach wasn’t adjudged to be severe by anyone.
