The Montana Criminal History and Your Own Copy
Montana is one of the states that lets anyone look up another person's statewide criminal history: the CHOPRS service lets anyone search public criminal history online by name, through the Montana 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.
Arrest Records Kept Locally in Helena

Together, the three agencies in Lewis and Clark County with all twelve months of 2025 on file reported 1,461 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
