And by the way public figures have to show intent to harm....a much higher requirement. That is they have to prove you knew the information was false and you said it anyway because you wished to harm the public figure
I do not believe that intent would be hard to prove if the accuser has no proof to substantiate the accusation. However, according to Doug From Upland the person Rob is talking about is dead. So perhaps that is why he will not name him. Because the person to whom he is referring to would be unable to respond the accusation so Rob feels why bother since that person can no longer do it to someone else.
