No, how she decided to defend the client was her choice. She could of had the moral, and intellectual courage to say " No, find someone else, I will not defend this man because I believe him guilty"
I had a lawyer once who did just that. A person he had been assigned to defend laughed while he told the lawyer how the elderly couple had begged for their lives but he killed them anyway. My lawyer somehow got the judge to let him out of defending the murderer.
A lawyer with a conscience...they do exist.
