Although "innocent until proven guilty" really only applies to who has the burden of proof in a trial situation, and doesn't actual indicate a belief in innocence in the absence of possible evidence to the contrary, I completely agree that a public Facebook page is nothing but a way to shame those who have been arrested, and who may or may not ever be convicted. It's one thing for that information to be publicly available to someone who goes looking for it. It is another entirely to put it right up there with cat memes and other "entertainment."
