Now it is a terrible business to mark a man out for the vengeance of men. But it is a thing to which a man can grow accustomed, as he can to other terrible things; he can even grow accustomed to the sun. And the horrible thing about all legal officials, even the best, about all judges, magistrates, barristers, detectives, and policemen, is not that they are wicked (some of them are good), not that they are stupid (several of them are quite intelligent), it is simply that they have got used to it.
Strictly they do not see the prisoner in the dock; all they see is the usual man in the usual place. They do not see the awful court of judgment; they only see their own workshop. Therefore, the instinct of Christian civilisation has most wisely declared that into their judgments there shall upon every occasion be infused fresh blood and fresh thoughts from the streets. Men shall come in who can see the court and the crowd, and coarse faces of the policeman and the professional criminals, the wasted faces of the wastrels, the unreal faces of the gesticulating counsel, and see it all as one sees a new picture or a play hitherto unvisited.
Our civilisation has decided, and very justly decided, that determining the guilt or innocence of men is a thing too important to be trusted to trained men. It wishes for light upon that awful matter, it asks men who know no more law than I know, but who can feel the things that I felt in the jury box. When it wants a library catalogued, or the solar system discovered, or any trifle of that kind, it uses up specialists. But when it wishes anything done which is really serious, it collects twelve of the ordinary men standing round. The same thing was done, if I remember right, by the Founder of Christianity.
