I encourage anyone interested in the consequences of whistleblowing to watch The Insider. A truly excellent film about a whistleblower at a tobacco company and the terrible things they did to try and stop him. Russell Crowe, Al Pacino, Bruce McGill, Christopher Plummer, many others.
A similar film is Silkwood, which is about the life of Karen Silkwood, who reported concerns about corporate practices related to health and safety in a nuclear facility where she worked. She was severely harassed by her employer and then died in a suspicious car accident.
Anybody who becomes the target of large orgs is going to have a bad time. Just think about the guy who was falsely accused of being the pipe bomber at the Atlanta Olympics after he saved people.
Thats the movie that prominently features "Amazing Grace", right? I still remember having watched it on public television in the late 80s. But all I really remember from the movie was amazing grace being played after the car crash scene.
So many good scenes. Personal favorite, grappling with the role of journalism: "What are you?! Are you a businessman or are you a newsman?" Such a powerful question.
