The criminal is not hard to understand. He is one who, from inherited defects or from great misfortune or especially hard circumstances, is not able to make the necessary adjustments to fit him to his environment. Seldom is he a man of average intelligence, unless he belongs to a certain class that will be discussed later. Almost always he is below the normal of intelligence and in perhaps half of the cases very much below. Nearly always he is a person of practically no education and no property. One who has given attention to the subject of crime knows exactly where the criminal comes from and how he will develop. The crimes of violence and murder, and the lesser crimes against property, practically all come from those who have been reared in the poor and congested districts of cities and large villages. The robbers, burglars, pickpockets and thieves are from these surroundings. In a broad sense, some criminals are born and some are made. Nearly all of them are both born and made. This does not mean that criminality can be inherited, or even that there is a criminal type. It means that with certain physical and mental imperfections and with certain environment the criminal will be the result. Seldom does one begin a criminal life as a full-grown man. The origin of the typical criminal is an imperfect child, suffering from some defect. Usually he was born with a weak intellect, or an unstable nervous system. He comes from poor parents. Often one or both of these died or met misfortune while he was young. He comes from the crowded part of a poor district. He has had little chance to go to school and could not have been a scholar, no matter how regularly he attended school. Some useful things he could have learned had society furnished the right teachers, surroundings and opportunities to make the most of an imperfect child. Early in life he does some desultory work in casual occupations. This of course is not steady, but he picks up what he can and keeps the job for a short time, sometimes quitting work because he is discharged and sometimes because, like most boys and men, he does not like to work. His playground is the street, the railroad yards or vacant lots too small for real play, and fit only for a loafing place for boys like himself. These gather nightly and talk of the incidents that interest most people, mainly the abnormal things of life and generally the crimes that the newspapers make so prominent to satisfy the public demand. He learns to go into vacant buildings, steals the plumbing, and he early learns where to sell it. From this it is only a short step to visiting occupied buildings at night. In this way he learns to be a burglar as other boys learn to play baseball or golf.
