ABSTRACT
Whistleblowing remains one of the most important sources of major stories and the cultivation and protection of whistleblowers is a central preoccupation for investigative journalists. Different from ‘sources’ who may have personal or family connections to the story, whistleblowers are almost always employees and inside. Many of the most important investigations and revelations of the Cold war and after were begun or developed by insiders prepared to risk their professional and personal positions by publicly exposing the criminal or unethical behaviour of their employers.
