Ethics

I previously posted questions from the fourth edition (1914) of Owen's "Quizzer Law Quizzer," which was apparently a book to help people studying for the bar examination.  (I bought the book for $8 at a used book sale.  It has an entire chapter on legal ethics questions.)

I promise that I'm not posting this just to get a rise from Monroe Freedman, but rather because I found it interesting.  Here are questions 28 and 29: 

28.  What was Lord Brougham's statement as to the duty of an advocate?

That, "an advocate, in the discharge of his duty, knows but one person in all the world, and that person is his client.  To save that client by all means and expedients, and at all hazards and costs to other persons, and among them to himself, if his first and only duty, and in performing this duty he must not regard the alarm, the torments, the destruction he may bring upon others.  Separating the duty of a patriot from that of an advociate, he must go on, reckless of consequences, though it should be his unhappy lot to involve his country in confusion."

29.  Is this statement defensible?

No; the only excuse or explanation for such a rash and dangerous statement is that it was made during the excitement of a trial.
