“Liquor sales are not protected by the Second Amendment.
The Fourteenth Amendment extends Second Amendment restrictions to state and local governments.”
The second amendment does not bar ALL state regulations of fire arms. From the beginning of the republic various states have had some limitations on fire arms, including some limitations on possession by minors. None of the laws were universal across all the states, but few were challenged as 2nd amendment violations.
A couple of limitations during the early republic, and a couple after reconstruction.
Not a significant history of regulation.
