Securing Civil Rights by Stephen P. Halbrook
Stephen P. Halbrook argues in Securing Civil Rights: Freedmen, the Fourteenth Amendment, and the Right to Bear Arms, Updated Edition that the Fourteenth Amendment was understood to protect the Bill of Rights, especially the Second Amendment right to bear arms, from infringement by the States. Halbrook also argues that the Supreme Court did not fully understand this argument in its decisions from the 1870s until District of Columbia v. Heller.
