Lawyers can't report the criminal behavior of their clients at will. Unless the client commits an act that endangers national security, it is against the professional ethics of lawyers to report the client, because lawyers have the obligation to keep secrets for the client. In addition, if a party is preparing or committing a criminal act, a lawyer can report it.
Legal objectivity:
