Which body works with the chief to oversee the police department?

The Police and Fire Commission plays a crucial role in overseeing the police department in conjunction with the chief of police. This commission is typically responsible for hiring and firing police officers, establishing policies, and ensuring compliance with laws and departmental regulations. By providing oversight, the commission helps maintain accountability within the police department and ensures that the chief operates in line with the community's expectations and legal standards.

While other bodies such as the Community Board or the City Council may influence policing and community relations, they do not have the same direct oversight authority as the Police and Fire Commission. The Department of Justice may provide guidelines and support but does not directly oversee Chicago's local police department. Therefore, the connection and responsibilities of the Police and Fire Commission make it the appropriate entity working alongside the chief to ensure effective governance and accountability within the police force.
