Subsequent research showed that the youth athletic leagues, recreation programs, and summer camp worked best along with urban planning and alternatives to incarceration as crime control policy. Such programs are non-entrepreneurial and non-self-sustaining, and they fail when local or central government does not make a sustained financial commitment to them. Although with hindsight, the school's attempts to map crime may have produced some distortions, the work was valuable in that it moved away from a study of pattern and place toward a study of function and scale.
