Which one of these options does NOT pose a risk at a government facility?

The option regarding a person expressing boredom with the US mission does not pose a direct risk at a government facility. While boredom may indicate disengagement or a lack of interest, it does not inherently suggest a threat or intent to harm. In contrast, the other choices depict behaviors that may indicate potential espionage or malicious intent.

Conducting surveillance can involve carefully observing a location or its security measures, and asking sensitive questions may suggest an effort to gather intelligence without clearance. Similarly, showing unusual interest in security protocols can indicate an intent to exploit vulnerabilities. These behaviors are typically associated with threats to the integrity and security of government facilities, making them causes for concern.
