Some reader of the preceding chapter may perhaps remark, "This is all very well so far as it goes. It doubtless is entirely true from a purely technical point of view. But that is only one side of the matter. How about the real criminals?" This is neither an unexpected nor an uninvited criticism. Who are the "real" criminals? Charles Dudley Warner says: "Speaking technically, we put in that [the criminal] class those whose sole occupation is crime, who live upon it as a profession and who have no other permanent industry. They prey upon society. They are by their acts at war upon it and are outlaws." Now the class of professional criminals to which Mr. Warner refers as contrasted with the great mass of criminal defendants as a whole is, in point of fact, relatively so small, and so easily recognized and handled, that it plays but an inconspicuous part in the administration of criminal justice.
