The second direction in which the criminal justice must maintain silence looks toward witnesses and accused. If, in the first instance, the cause of too much communicativeness was an over-proneness to talk; its cause in this case is a certain conceit that teases one into talking. Whether the justice wants to show the accused how much he already knows or how correctly he has drawn his conclusions; whether he wishes to impress the witness by his confidences, he may do equally as much harm in one case as in the other. Any success is made especially impossible if the judge has been in too much of a hurry and tried to show himself fully informed at the very beginning, but has brought out instead some error. The accused naturally leaves him with his false suppositions, they suggest things to the witness--and what follows may be easily considered. Correct procedure in such circumstances is difficult. Never to reveal what is already known, is to deprive oneself of one of the most important means of examination; use of it therefore ought not to be belated. But it is much worse to be premature or garrulous. In my own experience, I have never been sorry for keeping silence, especially if I had already said something. The only rule in the matter is comparatively self-evident. Never move toward any incorrectness and never present the appearance of knowing more than you actually do. Setting aside the dishonesty of such a procedure, the danger of a painful exposure in such matters is great.
