What organization acted as a citizen's advocate group to monitor local justice agencies?

The Chicago Crime Commission serves as a citizen's advocacy group focused on monitoring local justice agencies. This organization was established with the intent to foster public accountability within the criminal justice system, especially in Chicago. It has played a significant role in investigating and exposing corruption and inefficiencies within law enforcement and related agencies, ensuring that there is public oversight, and advocating for reforms as needed.

In contrast, the other organizations listed serve different roles within the legal and criminal justice framework. The American Bar Association primarily works to improve the legal profession and provide legal education, while the National Crime Prevention Association focuses on crime prevention strategies and community safety rather than direct oversight of justice agencies. The Justice Resource Center would likely provide resources and support for justice practices but does not specifically focus on advocacy in the same way as the Chicago Crime Commission. Thus, the distinctive function of the Chicago Crime Commission as a watchdog entity is what makes it the correct answer in this context.
