This about says it all:

"'Though originally the first ten Amendments were adopted as limitations on Federal power, yet in so far as they secure and recognize fundamental rights-common law rights-of the man, they make them privileges and immunities of the man as citizen of the United States, and cannot now be abridged by a State under the Fourteenth Amendment. In other words, while the ten Amendments, as limitations on power, only apply to the Federal government, and not to the States, yet in so far as they declare or recognize rights of persons, these rights are theirs, as citizens of the United States, and the Fourteenth Amendment as to such rights limits state power, as the ten Amendments had limited Federal power..."

Second Amendment to the United States Constitution:

"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."

Fourteenth Amendment to the United States Constitution:

"Section 1. All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws."

Rest my case.
