What Cook County State’s Attorney’s Office does
The Cook County State's Attorney's Office (CCSAO) is the principal county-government law enforcement and prosecution agency for Cook County, Illinois, led by State's Attorney Eileen O'Neill Burke. The office is described in source materials as the second-largest prosecutor's office in the country, with a headcount in the 1,001–5,000 range, and it prosecutes misdemeanor and felony offenses, pursues civil actions on behalf of the county, and operates specialized victim services. Its organizational structure comprises core bureaus—Criminal Prosecutions, Special Victims (domestic violence, sexual assault, crimes against children, hate crimes), Multi-Jurisdiction (organized crime, retail theft), Civil Actions, Juvenile Justice and Child Protection—alongside units such as the Conviction Integrity Unit, Law Enforcement Review Unit, and Choice Protection Unit.
The office's service portfolio includes task forces (CTA Task Force and Regional Transit Task Force) for transit crime, a dedicated Hate Crimes Unit with a specialized training curriculum for prosecutors, community engagement programs, gun violence reduction initiatives, and public transparency tools including Data Dashboards and a CCSAO Records Portal that supports FOIA requests with automated receipt confirmation. Underlying technology consists of government case management and legal prosecution systems; no public API, SDK, or AI/ML capability is documented.
CCSAO is funded entirely through Cook County government budgets and taxpayer appropriations; it does not generate commercial revenue, has no shareholders or parent company, and is not an investable entity. Service delivery to the public is direct via courthouse operations, victim services offices, and online portals, with geographic scope limited to Cook County. A partnership with the Chicago Police Department supports collaborative criminal investigations and prosecutions.
