I don't know if she's changed her mind but if she has I'd be willing to wager that it was because of political brow-beating, 'cause what she said back in March is a fact (the fact that virtually no one is following protocol when it comes to wearing these things, etc.) and just plain common sense. I mean, come on, face diapers.
