When appearing in court, an investigator should do which of the following?

When an investigator appears in court, dressing and acting professionally is essential as it sets the tone for how they are perceived by the judge, jury, and attorneys. A professional appearance reflects respect for the court and the legal process, which can positively influence the credibility of the investigator's testimony. This also ensures that the investigator is taken seriously and establishes a level of authority in the courtroom.

Maintaining a professional demeanor includes not only the choice of attire but also behavior, such as being punctual, courteous, and attentive. These attributes contribute to a positive impression and can aid in the overall effectiveness of their testimony. Conversely, casual interactions or disclosing private information can undermine the investigator's position and the integrity of the case being presented.
