The man's ego exceeds his abilities (IMO)... I don't know why anyone would hire the man. He was all over Larry King talking about how guilty the guy was -- until he contacted the family and took the case (for a million dollars).
While sad, it is un-avoidable.
Unlike the OJ case, Peterson's fame came from the murder and OJ murdered while famous.
Only the latter get away with it, witness the Menendez case, where again fame came as a result of the murder.
