I don’t think there’s a problem with their retraction. Shall the original story remain there, (and maybe also indexed by Google,) won’t that do exactly the same harm to the alleged site owner what the story claimed to had been done to the “victim”? To unpublish the story may lose some informative and educational value for the public, but since NPR's notice is detailed enough to explain what happened, such value should give way to the protection to the wrongly-indicted site owner.
