The city of Chicago (City) and the village of Oak Park, a Chicago suburb, have laws that are similar to the District of Columbia’s, but Chicago and Oak Park argue that their laws are constitutional because the Second Amendment has no application to the States. We have previously held that most of the provisions of the Bill of Rights apply with full force to both the Federal Government and the States. Applying the standard that is well established in our caselaw, we hold that the Second Amendment right is fully applicable to the States.
