Not familiar with the 14th that protects the 2nd everywhere, are you?
Actually the 2nd forbade
all governments in the U.S. from infringing the RKBA, even before the 14th came along.
But the 14th didn't hurt it any.
Actually it didn't. The bill of rights didn't apply to the States until the 14th
The First Amendment begins with
“Congress shall make no law…” Clearly, it was originally intended to constrain only the federal government.
The Fourth, Fifth, Sixth, Seventh, and Eighth Amendments pertain to routine law-enforcement, which has always been primarily a more localized responsibility. It seems absurd to suggest that state or lower law-enforcement were ever intended to be allowed, for example, to conduct unreasonable searches and seizures, to deprive people of life, liberty and property without due process of law, or to violate any of the other protections found in those Amendments. The wording of these Amendments is to suggest that certain abuses are not to be allowed; and not just to say that only the federal government is forbidden from committing them.
The wording of the Second Amendment is unique. It states a purpose, identifies one specific right, identifies to whom this right belongs, and forbids this right from being infringed. It doesn't say that only the federal government shall not infringe this right. It says this right shall not be infringed. This does not rationally allow for states to infringe this right, for counties, towns, cities, or any level of government, to infringe this right. It forbids them all from doing so.
