Which behavior should an investigator avoid during testimony?

In the context of providing testimony as an investigator, the correct behavior to avoid is explaining legal concepts. This is because the role of a witness, including a private investigator, is to present factual information and observations rather than to interpret the law or delve into legal nuances. Testimony should focus on the facts of the case as they pertain to the investigator's work and findings, leaving legal interpretations to the attorneys and the court.

When an investigator attempts to explain legal concepts, it can lead to confusion, misinterpretation, or even overstepping their boundaries, as legal expertise is outside the purview of their role. This can undermine the credibility of the testimony and distract from the core facts that need to be conveyed to the court. Therefore, sticking to straightforward, factual information that is directly relevant to the case is essential for a successful testimony.

The other behaviors, such as answering questions directly, using understandable language, and maintaining a neutral demeanor, are all crucial for effective testimony. They help ensure clarity, comprehension, and professionalism in a court setting.
