In its McDonald v. Chicago ruling the Court designated gun ownership a fundamental right, like freedom of speech.  Further, in its 2008 ruling in D.C. v. Heller, it ruled that "The Second Amendment protects a personal right to keep and bear arms for lawful purposes, most notably for self-defense within the home."  Note that the citation of self-protection in the home is not a restriction but merely an example of lawful purpose, hence the current debate cited.  Regardless, it is a fools errand to require further clarification of these rulings as in favor of the individual right to bear arms.
