Which Agency Holds a Report from Oswego
The report of an incident is released by the agency that took it; the court and the jail hold their own records of the same event, but not the report.
Inside Oswego that is the agency that reports to the FBI for the city (filed by the FBI as Oswego Police Department); outside it, the Kendall County Sheriff's Office.
The Joliet Police Department, the Plainfield Police Department, the Sandwich Police Department and two more are each listed by the FBI across several counties including Kendall County, so their arrests are not broken out for Kendall County here.
