Well it's relevant because it's the high crime, minority dominated cities that have attempted to disregard the Constitutional guarantee for the "right to bear arms". When that right was infringed it was necessary for the Supreme court to uphold that basic right. Hence Heller.

You don't see 'Heller vs. Cheyenne' or 'Heller vs. Winnemuca'. It's always a Chicago, DC, New York, Detroit that needs to protect themselves from those that have no regard for any law. That's why law abiding citizens in those chit holes have to fight for the right to protect themselves. The precise reason 'shall not be infringed' means just that. Unfortunately there are phvck sticks that attribute one Constitutional right being excercised as "judicial activism" but those same phvck sticks would cry their wasted education away over the infringement of 'free speech'. They are the same dipchits that (rightfully so) stand up for the occupy movement but decry any other excercise of rights.

Get it?
