NBC Nightly News provides coverage of the United States Supreme Court's decision in favor of Second Amendment incorporation in McDonald v. City of Chicago. Justice correspondent Pete Williams says it is "surprising" that the individual right of self-defense was not guaranteed nationwide until today. Chicago Mayor Richard Daley defiantly promises new anti-gun measures, while civil-rights activist Otis McDonald reflects on the victory. NRA Executive Vice President Wayne LaPierre promises to continue fighting the "byzantine labyrinth" of gun restrictions across the country, and Brady Campaign President Paul Helmke claims that McDonald is a "limited decision" for gun rights.
