What must an agency NOT advise an individual when receiving a positive KST File response?

When receiving a positive KST File response, it is important for the agency to avoid advising the individual that they may be on a terrorist watch list. This is because disclosing such information can have serious implications for the person's public perception, personal safety, and legal standing. Being on a terrorist watch list can evoke significant fear and stigma, and it might lead to unnecessary distress or retaliation.

Furthermore, the reasons for a KST File response can be complex, and the individual may not necessarily have any intention or involvement with terrorism; thus, implying that they are on a watch list without concrete evidence or further context may lead to misunderstandings. Agencies are trained to handle situations involving positive KST responses with sensitivity and discretion, emphasizing the need for confidentiality and due process.
