It is the right of the lawyer to undertake the defense of a person accused of crime, regardless of his personal opinion as to the guilt of the accused; otherwise innocent persons, victims only of suspicious circumstances, might be denied proper defense. Having undertaken such defense, the lawyer is bound by all fair and honorable means, to present every defense that the law of the land permits, to the end that no person may be deprived of life or liberty, but by due process of law.

The primary duty of a lawyer engaged in public prosecution is not to convict, but to see that justice is done. The suppression of facts or the secreting of witnesses capable of establishing the innocence of the accused is highly reprehensible.
