Whatever the type of criminal, he is usually motivated cardinally in the selection of a criminal career by a very positive distaste for actual work. If he is an itinerant, half-baked tradesman, he will take a "flyer" here and there at his craft, especially while the police are combining for those of his kidney; but consecutive, concentrated endeavor in a humdrum groove he will not abide. And since his instinctive impulsions are those of the parasite, and his appetites those which require some little of money to satisfy, he takes naturally to the tools of the crook.
What crooked tools he will select will depend largely upon his natural fitness to employ them. Usually he aims to excel in his particular line, and he will usually choose the line in which he thinks he can do so. If he is rough-hewn, likes the feel of rough tools, and has the knack of handling them, he will likely enlist in the yeggman division. One whose tastes are more refined and temper more timorous, will naturally go in for forgery, if he guides a cunning tracing pen. The big-tent men, with nerve and daring, take the longest chance with superior intelligence and engraving skill, and keep paying tellers agog. Those who pack a plausible "gift of gab," backed by no mean knowledge of the intricacies of high finance, as well as where the same does and does not trench upon legal proscriptions, constitute the Wallingfords of "fake" promotion; and lesser lights of the same persuasion who have neither the smoothness of personality, approach and attack of their bigger brothers, form the "now-you-see-it-and-now-you-don't" fraternity of endless variety and variety of working tools. The sneak-thief runs true to his name, and is properly most dreaded by the clan criminal, some of whom he is most liable to "double-cross," and others to euchre with the cards of the "stool-pigeon." Second-story operators, his near relations, are commonly drug-soaked neurotics with a penchant for the air-line, and bizarre ways and means of getting to it and getting away with it.
Since the temptation is great to get a whole lot for nothing and to do it quickly, and since it is so easily done these days, the marauding criminal will be most any type of criminal; but he is commonly a murderously-inclined high-wit of his class of exceptional nerve and resourcefulness, to the first of which he is commonly helped by such as heroin, and to the second by that spitting devil in spurious hands--the automobile. When he is a low-wit, and plans accordingly, the "finest" betimes get him; and when they do, he is a low-wit indeed if he cannot flash an indestructible alibi. Why not, when the testimony of his retainers is accepted at its face value in our courts of law?
