Among the real criminals, it is the habitual offenders who are truly important. Many of these may be thought of as delinquents grown older and more experienced, for men who have lived upright lives for twenty years are not likely to change their habits overnight. The causes of their criminality are written in the history of the forces that played through them during their childhood and youth. Their lives are the normal products of a faulty past. When the market reaches strategic points they notify their customers that they have been sold out. Flynn cites an instance illustrative of this practice a board chairman persuaded his codirectors to go into the market and buy the stocks of another company in order to effect a merge. When the committee then began its purchasing with a resulting rise in the price of the stock, the chairman sold his own shares to his own company at a profit of $165,000.
