When are people like Nancy Grace and Bill O'Reilly going to go into hiding because of death threats?

Although their behaviour has been reprehensible, indulging in vigilante behaviour is just as bad. How is threatening to kill someone superior? This entire circus is becoming a parade of desperate insults, threats and media whoring. It will stop when 1 - people stop listening to rabble rousing idiots like Grace and O'Reilly 2 - people stop posting encouragements to commit murder. Until then, the justice system will be viewed as a farce.
