These are simply extensions of earlier flawed decisions that unjustifiably overturned precedent in the Slaughterhouse cases.
It is undoubtedly true that all citizens capable of bearing arms constitute the reserved military force or reserve militia of the United States as well as of the states, and, in view of this prerogative of the general government, as well as of its general powers, the states cannot, even laying the constitutional provision in question [the 2nd amendment] out of view, prohibit the people from keeping and bearing arms, so as to deprive the United States of their rightful resource for maintaining the public security, and disable the people from performing their duty to the general government. But, as already stated, we think it clear that the sections under consideration [state laws regulating the conduct of public parades] do not have this effect.Federal courts deliberately ignored this part of the Presser case, even stating that the case stands for the exact OPPOSITE proposition. Such is the mendacity of the federal courts vs. the right to keep and bear arms. SCOTUS knew this was going on, too, and chose to allow it to continue for decades. To this day, the "law" (as asserted by the mendacious courts) is that Presser stood for the proposition that states could infringe the right to keep and bear arms.
