MADISON, Wis. — Roxane Stillman is a 62-year-old kidney cancer survivor with a heavy sense of right and wrong.

With her righteous indignation driving her on, the rural Madison woman two weeks ago found herself chasing down an alleged vandal perhaps more than 30 years her junior at the Jefferson County Fair.

Stillman is the key witness in a political disorderly conduct case with broader government transparency implications.
