I can't tell you the number of people who have asked David, "Would you defend a person who you knew was guilty?" (Actually, they don't ask that much anymore....we know that that's all he does defend.) I loved this quote in response to a similar question:
"Cousin Steve, I can't understand your defending the Chinns, even though they are your first cousins. Surely you don't want to make slavery legal in Illinois?"
"No, Mary, that's not my intention; but everyone is entitled to a defense of his person and property at law. If the issue of slavery is to be settled, then both sides of the case should be presented with the utmost precision."
"But if you plead the case for slavery, won't people conclude that you are in in favor of it?"
"I don't think so, Mary; lawyers don't have to subscribe to everything their clients believe, in fact they couldn't possibly. The lawyer is an officer of the court, his duty is to see that all of the law bearing on a case is brought forth. I intend to do my job thoroughly and dispassionately."
