Supreme Court refuses to hear Second Amendment case

The Supreme Court refused to review a 9th Circuit decision upholding a San Francisco gun law.  Only 2 Justices voted to hear the case.  A refusal to hear a case is not a legal affirmation of the lower court decision.  The Court needs to clarify the scope of Second Amendment rights. The last U.S. Supreme Court case on the amendment was in 2010 in McDonald v. Chicago, where the Court held that the Second Amendment applies to the states.
