Glenn's publication was aimed at teaching others about the requirements. He is not at fault when a client doesn't listen or takes on someone after wrongdoing has already occurred. If Glenn personally participated in any wrongdoing, it would hurt not only his reputation but also his career. If he did not participate, the only ones who may look down on him are die-hard CMKXers who have had problems separating the role of a company's attorney verus its officers/directors.
Did OJ Simpson's attorneys have their reputations tarnished among those who matter? No. They took on more high-profile cases and became even richer.
