blowing the whistle

Reporting hidden misconduct

Blowing the whistle is reporting wrongdoing, especially by an insider exposing misconduct within an organization: She blew the whistle on the company's fraudulent accounting practices.

The image comes from a referee's whistle stopping play when rules are broken.

Someone who does this is a whistleblower.

The act can be heroic or treacherous depending on perspective—celebrated as courage or condemned as betrayal.
