I was reading the US v. Miller case as I occasionally do, and came across a reference to the case Presser v. Illinois. This is a Supreme Court case in which Presser and 400 men marched in Chicago in 1886. He was arrested for violating a State law that prevents armed parades without consent of the Governor. The SC affirmed the Illinois SC decisiom that the convition should stand. Generally this case is quotes as being in the negative for gun rights, however as I actually read it there was a statement that the Supreme Court made that basically said states CAN'T restrict firearm ownership! Read it below.
[b]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 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.[/b]
