Weak argument, especially in light of Heller. DC tried to make this exact same argument (that residents could own rifles, therefore there was no problem with banning handguns).FEOS wrote:
My statement about the 2nd Amendment stands. The right to keep and bear arms was not impacted by restrictions on the types firearms that can be owned, as firearms can still be owned.
There are not many SCOTUS cases directly relating to the 2nd. Heller was huge, but intentionally limited in scope. The 1939 Miller case is the next most important case in today's terms. Many argue that it was a DEEPLY flawed decision, based on factors like the "militia use" idea, the fact that SBSs are in use by the military, and THE DEFENDANT WAS NOT REPRESENTED. Prior to that, there were a few cases, but those were before the 14th Amendment. Presser v. Illinois is big, but probably wrong now that the 14th exists.
