The authors conclude that all whistleblowing cases analyzed in this study were effective with regard to the five factors: (1) type of whistleblowing; (2) role of mass media; (3) documentation of evidence; (4) retaliation; and (5) legal protection. The chapter highlights all cases as ones that inspired and led to great institutional and legal reforms. Finally, the results also suggest that Peru and Thailand should enact a whistleblower protection law; South Korea should broaden protection for whistleblowers; and the United States should provide multiple avenues for interpretation and enforcement of the law, with full access to the legal system’s due process channels. Each country should establish a better whistleblower system in order to discover and deter corruption and fraud.
