A whistleblower is a person who raises a concern about wrongdoing occurring in an organization or body of people. Usually this person would be from that same organization. The revealed misconduct may be classified in many ways; for example, a violation of a law, rule, regulation and/or a direct threat to public interest, such as fraud, health/safety violations, and corruption. Whistleblowers may make their allegations internally (for example, to other people within the accused organization) or externally (to regulators, law enforcement agencies, to the media or to groups concerned with the issues).
