A "Confidential Source" refers to an individual or entity that provides information to journalists, law enforcement, or other organizations while remaining anonymous. This practice is crucial for protecting the source's identity, especially when the information involves sensitive topics like whistleblowing or criminal activity. Confidential sources can help uncover important stories or evidence that might not be accessible otherwise. However, the use of such sources raises ethical questions about transparency and accountability in reporting, as it can sometimes lead to challenges in verifying the accuracy of the information provided.
