Final answer:
The interviewer supports the idea that juvenile justice quality depends on geography by noting the spatial patterns of crime and how the cultural ecology of neighborhoods impacts juvenile delinquency rates.
Step-by-step explanation:
The idea that 'the quality of juvenile justice can often depend on geography' is supported by the interviewer through several points. Firstly, there is an acknowledgment that criminal justice issues are deeply rooted in geographic aspects. The spatial patterns of crime, the differences in victimization rates, laws, and the varied approaches to punishment and rehabilitation are all geographically influenced. These variations are critical because they demonstrate how geographic location can impact the effectiveness of juvenile justice systems. For instance, the text references the work of Shaw and McKay, who found that the rate of juvenile delinquency declined when families moved from certain neighborhoods it was not ethnicity, but rather the social environment or cultural ecology of specific areas that affected juvenile crime rates. As such, geography matters greatly in understanding and addressing crimes by juveniles.
