Which Agency Holds a Report from Mason
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 Mason that is the agency that reports to the FBI for the city (filed by the FBI as Mason Police Department); outside it, the Ingham County Sheriff's Office.
The FBI's list also places the Ingham County State Police in Ingham County; a report taken on a state highway by it comes from that agency's own records office.
The FBI's list also carries Michigan State University and Lansing Community College (campus police), each with a records office of its own.
