Most people are familiar with the text, "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" as the Bill of Right's 2nd amendment. There are, of course, the usual controversies regarding exactly what that entails but one issue has been fairly established is that American citizens may own firearms. And that is the issue being challenged by the Chicago Gun Case by the NRA specifically for senior citizen Otis McDonald over his right to own and carry his shotgun to protect himself from gangs. Chicago, amongst other cities and municipalities, bans handguns and automatic weapons inside of city limits ostensibly to prevent violent crime by eliminating the tools. Which raises the Otis McDonald's question - does the authority exist for local/state ordinances to trump Constitutionally protected rights and federal laws?
