Which Agency Holds a Report from Washtenaw County
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.
In Washtenaw County that is the Washtenaw County Sheriff's Office for the unincorporated county and for any city that contracts with it for police service, and the agency that reports for a city where the city has one of its own.
The FBI's list also places the Washtenaw County State Police in Washtenaw County; a report taken on a state highway by it comes from that agency's own records office.
The FBI's agency list also places one other agency and three campus police departments in Washtenaw County, each with a records office of its own.
