The Supreme Court decision is limited to what the federal government can restrict regarding firearms. It also, was clear this decision did not invoke the 14th Amendment that would require States to comply with the decision. It only says individuals are allowed to own, possess and use in self defense a handgun under federal jurisdiction, not State. That is why all the lawsuits now against San Fran, Chicago and its suburban communities. The outcome of these cases under State Law and this Supreme Court decision will determine what, where, when, and how firearms may be restricted under law. Not that I agree with any anti gun positions, but to clarify this decision. And this is only my understanding of the decision and not legal advice or interpretation.
