" The built-in excuse has become as standard in discussions of black crime as it is unsubstantiated, except by peer consensus among the intelligentsia. The phrase “troubled youth” is a common example of the unsubstantiated but built-in excuse, since those who use that phrase usually feel no need to offer any specific evidence about the specific individuals they are talking about, who may be creating big trouble for others, while enjoying themselves in doing so.
