Final answer:
A supervisor must inform a citizen that their allegations of misconduct must be formalized and substantiated to proceed with an investigation within the context of intelligence community oversight.
Step-by-step explanation:
When a supervisor receives an allegation of misconduct from a citizen, the citizen must provide a formal and substantiated report for the investigation to move forward. This is in line with protocols that ensure allegations are credible and serious enough to warrant an inquiry. In the context of intelligence community oversight, according to 50 U.S.C. § 3033(k)(5)(A), an employee connected to the intelligence community can report a complaint or urgent concern to the Intelligence Community Inspector General (ICIG). Moreover, individuals are protected when making such reports, ensuring a safe channel of communication with congressional bodies.
