Remember when Nancy Grace recklessly speculated that Whitney Houston may have been murdered? Well, today, while standing in as co-host on The View, Barbara Walters confronted her about those remarks, and Nancy got super defensive, throwing down with the rest of the ladies, saying, "I'm sure it's all fun to sit around and throw stones behind a coffee cup…" making the audience go, "Ooh." And she didn't let up. She insisted that she was in the right when she implied that someone may have pushed Whitney Houston into a tub of water.
