You’re welcome.
It is interesting to look at the history of jurisprudence and popular sentiment. It doesn’t seem that gun rights were that big of a national issue for most of US history (maybe because they weren’t threatened, or weren’t perceived to be threatened?).
Wikipedia actually has a pretty good run down of major court cases bearing on the right to bear arms: List of firearm court cases in the United States - Wikipedia
- Cruikshank 1875: The Supreme Court ruled that the second amendment only applied to congress. This was after the 14th amendment, but it would be another 135 years before the second amendment was determined to fully apply to state and local governments.
- Presser 1886: The Supreme Court reiterated that the second amendment only applies to congress and the “national government,” but stated that “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. But, as already stated, we think it clear that the sections under consideration do not have this effect.” Interesting principle! This decision also stated clearly that there is no constitutional protection for forming militias, parading, drilling, etc. The defendant in this case was involved in forming socialist militias to fight Pinkerton armies in the labor wars.
- Miller 1939: The court upheld a ban on sawed off shotguns on the grounds that they weren’t properly military weapons. The case also upheld the right of the US gov to regulate interstate transfer of guns.
- Heller 2008: Fully divorced the second amendment from militia service for the first time. Grounded the right in self-defense, or other lawful end.
- McDonald 2010: Fully incorporated the second amendment. The protections and prohibitions of the second amendment (whatever those are!) now extend to state and local governments.
Bearing arms has been mentioned in other places as well, most famously in Dred Scott where Taney famously wrote “It would give to persons of the negro race, who were recognized as citizens in any one State of the Union, the right to enter every other State whenever they pleased, singly or in companies, without pass or passport, and without obstruction, to sojourn there as long as they pleased, to go where they pleased at every hour of the day or night without molestation, unless they committed some violation of law for which a white man would be punished; and it would give them the full liberty of speech in public and in private upon all subjects upon which its own citizens might speak; to hold public meetings upon political affairs, and to keep and carry arms wherever they went.” Implying that white people at the time had the right to carry arms “wherever they went.”
Also, to push further on Taney’s racial angle the black codes and later Jim Crow laws in the south often prohibited black men from owning or bearing guns and the Mulford Act prohibited carrying loaded guns in public after the Black Panthers walked into the California Capitol with guns.
