Which action is NOT part of counterintelligence inquiries?

Conducting psychological evaluations is not considered a part of counterintelligence inquiries. Counterintelligence focuses on protecting national security by preventing espionage, sabotage, and other intelligence threats, primarily through investigations and operations. These typically involve gathering and analyzing information, assessing risks, and coordinating with law enforcement when necessary.

In contrast, psychological evaluations are related to assessing individuals' mental states, motivations, and behaviors, which while valuable in other fields, do not directly contribute to the goals and methods of counterintelligence. This type of evaluation might be relevant in a broader security context, such as personnel security or mental health assessments, but it does not align with the tactical and investigative nature of counterintelligence work.

The other options are integral components of counterintelligence efforts. Coordinating investigations or operations is required to efficiently manage resources and respond to threats. Referring cases to law enforcement ensures that any criminal activities uncovered are appropriately addressed. Developing sources for intelligence information is crucial for gathering insights that might indicate insider threats or other security issues.
