Which Agency Holds a Report from Oak Grove
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 Oak Grove that is the agency that reports to the FBI for the city (filed by the FBI as Oak Grove Police Department); outside it, the Jackson County Sheriff's Office.
The FBI's agency list also places two campus police departments and three other agencies in Jackson County, each with a records office of its own.
The Pleasant Hill Police Department is listed by the FBI across two counties including Jackson County, so its arrests are not broken out for Jackson County here.
