The Wisconsin Criminal History and Your Own Copy
Wisconsin is one of the states that lets anyone look up another person's statewide criminal history: the Wisconsin Online Record Check System lets anyone run a name-based check, through the Wisconsin Department of Justice. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it.
