Another interesting aspect of this case is that some years after the decision, one of the judges involved in the decision admitted that he had, in fact, used a short barreled shotgun in his service during WWI. However, as you (and the court) stated, there was no judicial notice and the govt lied it's ass off with the result being the foundation for almost all gun control laws to follow.
I believe you, but do you have a source for this? It would be interesting to add to my "gun control" files, and to show to anti-gun morons to prove that "their case" is a big lie. Thanks.
