I can't reveal my sources

Origin

The cornerstone of investigative reporting and whistleblowing, the principle behind "I can't reveal my sources" solidified in the 20th century as a crucial ethical standard. While the protection of informants dates back centuries, the specific phrase became deeply embedded in public consciousness through dramatic legal battles and journalistic showdowns. Reporters and writers understood that to break the trust of their sources was to sever the pipeline of vital information, often from those risking everything to expose wrongdoing. This steadfast refusal isn't just a legal defense; it's a moral imperative, a shield for the vulnerable, ensuring that truths, no matter how uncomfortable, can still find their way into the light, even when the messenger remains in the shadows.
