Which situation could indicate an inappropriate level of interest in sensitive information?

Requests for unauthorized information are a clear indicator of an inappropriate level of interest in sensitive information because they suggest that an individual is seeking access to information they are not officially cleared or entitled to obtain. Such requests can signal potential espionage activities or attempts to access data that could compromise security or operational integrity. Recognizing this behavior is crucial in counterintelligence efforts, as it allows appropriate measures to be taken to protect sensitive information and prevent unauthorized disclosures.

In contrast, foreign entity visits, while they may warrant scrutiny, do not inherently indicate an inappropriate interest unless coupled with other suspicious behaviors. Irate visitors could suggest dissatisfaction or other issues but do not necessarily relate to an interest in sensitive information. Camera restrictions typically pertain to security measures rather than indicating someone's interest in sensitive information.
