The problem of corruption is that violations are often hidden and corruption acts are silenced; so someone should not be afraid to report it in the public interest. This is the function of the whistleblower. Exposing corruption and protecting whistleblowers are important for any society, as modern experience unfortunately shows that neither public entities nor private companies can or do not want to solve their own problems. If all government agencies worked honestly and transparently, there would be no need for whistleblowers, as the system would be cleaning itself. But in the struggle for power and profits, the stakes have become so high that corruption only thrives because leaders do not want to be held accountable.
