WASHINGTON (AP) — Silent on central questions of gun control for two centuries, the Supreme Court found its voice Thursday in a decision affirming the right to have guns for self-defense in the home and addressing a constitutional riddle almost as old as the republic over what it means to say the people may keep and bear arms.

The court's 5-4 ruling struck down the District of Columbia's ban on handguns and imperiled similar prohibitions in other cities, Chicago and San Francisco among them. Federal gun restrictions, however, were expected to remain largely intact.

The court's historic awakening on the meaning of the Second Amendment brought a curiously mixed response, muted in some unexpected places.
