The Second Amendment is one of the few sections of the US Constitution’s Bill of Rights that hasn’t been applied to the States. The others being:
It should be noted, however, that most state constitutions also have these protections. For example the right to bear arms appears in some form in 44 state constitutions.
3rd: the prohibiting the quartering of soldiers in a private residence.
5th: the right to a grand jury indictment
7th: the right a to jury trial in civil cases
8th: the right against excessive fines and punishments.
It’ll be interesting and I look forward to reading what the court hands down.
