Which of the following does NOT pose a risk to security at a government facility?

The choice indicating a person showing boredom with the US mission does not inherently pose a direct risk to security at a government facility. While it may signal a lack of engagement or interest, boredom alone does not suggest any intent to undermine security or commit an act that could risk the safety of personnel or operations.

In contrast, the other options represent behaviors that could indicate potential security threats. Expressing discontent with security measures may signal grievances that could escalate into more serious actions. Being overly friendly might mask ulterior motives, such as gathering information or conducting surveillance. Refusing to adhere to security protocols is a direct violation of procedures designed to protect the facility, which could create vulnerabilities. Thus, while all behaviors should be monitored, showing boredom in itself does not equate to a security risk like the other behaviors do.
