With recent events, some folk have been trotting out the argument that the 2nd Amendment is a “collective right” or one that exists only so that the States can arm State government troops (“Militia” as these folk would have it). They argue that the Heller and McDonald decisions (the first confirming RKBA as an individual right, the second incorporating it on the individual States) is wrong.
This fails on several grounds.
First, there’s the grammatical:
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.
