These people are not to be confused with those specific men of power who, in the attempt to show what they can do, go further than in truth they should. There are indeed persons of talent who are efficient, and know it, whether for good or evil, and they happen to belong both to the class of the accused and of the witness. The former show this quality in confessing to more than they are guilty of, or tell their story in such a way as to more clearly demonstrate both their power and their conceit. So that it may happen that a man takes upon himself a crime that he shares with three accomplices or that he describes a simple larceny as one in which force had to be used with regard to its object and even with regard to the object’s owner; or perhaps he describes his flight or his opponents’ as much more troublesome than these actually were or need have been. The witness behaves in a similar fashion and shows his defense against an attack for example, or his skill in discovery of his goods, or his detection of the criminal in a much brighter light than really belongs to it; he even may describe situations that were superfluous in order to show what he can do. In this way the simplest fact is often distorted. As suspects such people are particularly difficult to deal with. Aside from the fact that they do more and actually have done more than was necessary, they become unmanageable and hard-mouthed through unjust accusations. Concerning these people the statement made a hundred years ago by Ben David[87] still holds: “Persecution turns wise people raw and foolish, and kindly and well disposed ones cruel and evil-intentioned.” There are often well disposed natures who, after troubles, express themselves in the manner described. It very frequently happens that suspects, especially those under arrest, alter completely in the course of time, become sullen, coarse, passionate, ill-natured, show themselves defiant and resentful to even the best-willed approach, and exhibit even a kind of courage in not offering any defense and in keeping silent. Such phenomena require the most obvious caution, for one is now dealing apparently with powerful fellows who have received injustice. Whether they are quite guiltless, whether they are being improperly dealt with, or for whatever reason the proper approach has not been made, we must go back, to proceed in another fashion, and absolutely keep in mind the possibility of their being innocent in spite of serious evidence against them.
