For those not familiar with these cases ---
Link to -- Presser v. Illinois
Link to --- U.S. v. Miller, et al
Link to ---descriptions of Supreme Court gun cases
The description of Presser doesn't capture the effort by the State of Illinois strategically to restrict RKBA by statute.
The Court's opinion in Cruikshank is a cloud of squid ink, deliberately obscurantist IMHO, but I took the salient points from it that, notwithstanding the enforcement clause of the 14th Amendment, the Court chose to uphold neither the Civil Rights Act of 1866 nor the Enforcement Acts of 1870 (there were two of the latter, the later a refinement of the first), and indeed abrogated any federal role in the incorporation of the "privileges and immunities" clause and the Bill of Rights generally to the States.
They threw the black complainants in the original federal case on the mercy of the white-supremacist government of Louisiana. To the wolves, in other words.
Cruikshank wouldn't withstand inspection for more than about 15 minutes today, again IMHO.
