I thought that law enforcement had always been allowed to do this in sting operations and the like. The police are under no obligation to tell the truth when confronting a potential suspect. Yes, their wording to her may have been deceptive, but, frankly, I don't have much faith in someone saying, "Yes I gave them consent to use my photos, but not like this!" It sounds a good deal like buyer's remorse.
If the officer in question were reasonable, he would have used images that are in public record of her, so I can see the outrage to that portion as reasonable, but, frankly, I don't see how this is terribly surprising and front page news.
PS...since when is BuzzFeed considered to be even remotely a reputable news source?
