My fifth category is made up of what a friend calls "the unknown thief," whom he considers the most dangerous and despicable of all. He means, by the unknown thief, the man in official life, or in any position which permits of it, who protects, for the sake of compensation, the known thief. "If you will catch the unknown thief," he has frequently said to me, "I will contract to apprehend and convict the known," and he believes that until we make a crusade against the former, the latter is bound to flourish in spite of all our efforts. He sees no use, for instance, in spending weeks and sometimes months in trying to capture some well-known criminal, as long as it is possible for the man to buy his freedom back again, and it is his firm belief that this kind of bargaining is going on every day.

Although there was no doubt that the unknown thief was to be located on any "beat," if looked for, my instructions were not to disturb him unless he seriously disturbed me, and as he made no effort to interfere with my work I merely made a note of his case when we met, and doubtless he also "sized me up" from his point of view. How strong his class is, compared with the others, must remain a matter of conjecture, but I have put his class fourth in my description because it is the quality of his offences, rather than their quantity, which makes his presence in the criminal world so significant. There are those who believe that he is to be found in every town and village in the United States, if enough money is offered him as bait, but I have not sufficient data to prove, or to make me believe, such a statement. The league between him and the known thief—the man whose photograph is in the "rogue's gallery"—is so close, however, that I have devoted special chapters to both offenders.

Of the last category, the man whom I have called the irresponsible criminal, there is not much of interest or value that I have to report. While acting as police officer I practically never encountered him in the open, and the few members of his class that I saw in prisons seemed to me to have become irresponsible largely during their imprisonment. Perhaps I take a wrong view of the matter, but I cannot get over the belief that the majority of offenders, particularly those who are ranked as "professionals," are compos mentis as far as the law need require. In every department of the prisons that I visited, men were to be seen who gave the impression of being at least queer, but they formed but a very small part of the prison population, and may very possibly have been shamming the eccentricities which seemed to indicate that they were on the border line of insanity. For this reason, and, as I say, because I met none in the open, it has seemed fair to put this class last.

The foregoing classification is naturally not meant as a scientific description in the sense that the professional criminologist would take up the matter. I have merely tried to explain how the criminal situation in the United States seems to the man whose business it is to keep an official watch over it. I may have overlooked, in my classification, offenders that some of my brother officers would have included, but it stands for the general impression I got of the criminal world while in their company. To attempt to estimate the numerical strength of these classes as a whole would land one in a bewildering bog of guesses. It is only recently that we have made any serious effort to keep a record of offenders shut up in penal institutions, of crimes which have been detected and of offenders who have been punished, and it is a fact well known in police circles that there is a great deal of crime which is never ferreted out. There is consequently very little use in trying to calculate the number of the entire criminal population. The most that I can say in regard to the question is that never before has this population seemed to me to be so large, but I ought to admit that not until my recent experience have I had such an advantageous point of view from which to make observations.


CHAPTER II.

THE PROFESSIONAL CRIMINAL.

In appearance and manner the professional criminal has not changed much in the last decade. I knew him first over ten years ago, when making my earliest studies of tramp life. I saw him again five years ago, while on a short trip in Hoboland, and we have met recently on the railroads; and he looks just about as he did when we first got acquainted.

Ordinarily he would not be noticed in mixed company by others than those accustomed to his ways. He is not like the tramp, whom practically any one can pick out in a crowd. He dresses well, can often carry himself like a gentleman, and generally has a snug sum of money in his pockets. It is his face, voice, and habits of companionship that mark him for what he is. Not that there is necessarily that in his countenance which Lombroso would have us believe signifies that he is a degenerate, congenitally deformed or insane, but rather that the life he leads gives him a look which the trained observer knows as "the mug of a crook." He can no more change this look after reaching manhood than can a genuinely honest man, who has never been in prison, acquire it. I had learned to know it, and had become practised in discovering it, long before I became a policeman. It took me years to reach the stage when in merely looking hurriedly at a criminal something instinctively pronounced him a thief, but such a time certainly comes to him who sojourns much in criminal environment. There are, of course, certain special features and wrinkles that one looks for, and that help in the general summing up, but after awhile these are not thought of in judging a man, at least not consciously, and the observer bases his opinion on instinctive feeling. Given the stylish clothes to which I have referred, a hard face, suspicious eyes which seem to take in everything, a loitering walk, a peculiar guttural cough, given by way of signal, and called the thief's cough, and a habit of lingering about places where a "sporty" constituency is usually to be found, and there is pretty conclusive evidence that a professional thief is in view. All of this evidence is not always at hand; sometimes there is only the cough to go by, but, the circumstances being suspicious, any one of them is sufficient to make an expert observer look quickly and prick up his ears.

In New York City, for instance, there are streets in which professional thieves can be met by the dozen, if one understands how to identify them, and it is only necessary to pass a few words and they can be drawn into conversation. Some are dressed better than others,—there are a great many ups and downs in the profession,—and some look less typical than the more experienced men,—it takes time for the life to leave its traces,—but there they stand, the young and old, the clever and the stupid, for any one who knows how to scrape acquaintance with them. They are the most difficult people in the world to learn to know well until one has mastered their freemasonry, and then they are but little more fearful of approach than is the tramp.
