Which of the following is considered a good citizen informant?

A good citizen informant is typically characterized by their reliability and lack of personal agendas that may compromise the information they provide. In this context, a person who has never been in trouble with the law is often viewed as a trustworthy source. This is because they don't have a history of criminal behavior that might signal a motive to provide false or skewed information, such as seeking leniency for their own legal issues or attempting to manipulate the situation for personal gain.

This type of informant can provide valuable insights into drug-related activities from a perspective of community concern rather than self-interest. Their credibility is often viewed more favorably by law enforcement and can lead to more effective investigations.

The other options present various issues. Individuals with a criminal history may have motivations that affect the truthfulness of their information. Paid informants may also have incentives that could lead to biased or unreliable intelligence. Similarly, fellow officers are typically held to different standards and may not fit the traditional profile of a "citizen" informant. Therefore, the choice emphasizing an individual with no prior encounters with the legal system aligns best with the definition and expectations of a good citizen informant.
