How about spending a little time on the history of the 2A as a sop to slave owners? The 2A has always been portrayed as a response to the fear of a standing army but that's only part of the story.
The rest is that Patrick Henry, saw danger in Article 1, Section 8:
He feared that this language would override state militias that were used to pursue runaway slaves and suppress rebellions. He explicitly invoked this reasoning while arguing against ratification of the Constitution. In response, James Madison wrote the 2A, in which militias, in which in the south only white men were armed, were protected:
To provide for organizing, arming, and disciplining, the Militia, and for governing such Part of them as may be employed in the Service of the United States, reserving to the States respectively, the Appointment of the Officers, and the Authority of training the Militia according to the discipline prescribed by Congress;
Madison, who was also a slave owner, drew a connection between the militia and the right to bear arms as a specific response to Henry's objection to Article 1 perhaps being used by the federal government to keep the Virginia state militia, which primarily dealt with slave issues, from doing its job. Virginia was needed for ratification and without the militia being protected, that wasn't going to happen.
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.
Scalia found an individual right to bear arms, but Alito's new basis for originalism opens up the very real possibility of Heller being overturned. And now you have the rest of the story - the 2A was, in part, required to get slave states to ratify the Constitution.
