Civilian oversight of law enforcement in the US dates back to the Progressive Era due to concerns regarding the effect of corruption in policing at the federal, state and local levels.  Many took the form of appointed commissions to review policing practices, and locally, some included the direct authority over their police departments.  At times, there was political interference, which impacted the integrity of the appointed commissions.

The first assembly of citizens to receive complaints of misconduct against police officers date back to the 1920’s. The demand for citizen or community oversight first occurred in the 1940’s. Many of these early review procedures were short lived due to insufficient fiscal support, lack of resources and served as only venues to receive and review police complaints. Further development of community oversight was strongly influenced by the civil rights movement and the perception in many quarters that law enforcement responded to racial unrest with excessive force.

Community review revived in the early 1970s as urban African-Americans gained more political power and as more white political leaders came to see the need for improved police accountability. They were more successful because they had more powers and enhanced resources. There was then a momentum of increased oversight agencies, responsibilities and policies, which usually came into existence due to a high-profile cases of alleged police misconduct (usually a shooting or other physical force incident), often involving white officers and suspects of color. Racial or ethnic profiling and allegations of discrimination are often at the heart of movements to introduce community oversight.

By the early 2000s, community review became more widespread in the United States. Roles of community review of law enforcement have evolved in cities, counties and towns using a form or hybrid of recognized community oversight models. The models include review, investigation and auditor/monitor focused.
