The factor that enhances a witness's credibility during a trial involves their level of involvement and perspective regarding the events in question. A witness who is a non-involved third party brings an objective viewpoint that is essential for assessing the situation without bias or personal interest. This type of witness is generally seen as more credible because they have no stake in the outcome, minimizing the possibility of skewed testimony.

In contrast, a witness who is intoxicated may struggle to provide reliable testimony, as their state can impair judgment and recall, casting doubt on the accuracy of their account. A sober individual with no direct knowledge would lack essential details that can substantiate their credibility in providing testimonies about the event. Similarly, a second-hand account is often viewed as less credible because it relies on someone else's interpretation of the events rather than the witness's direct experience, which can introduce inaccuracies and confusion.

Thus, the credibility of a witness is significantly impacted by their direct knowledge, involvement, and objectivity, with an unaffected third-party perspective being the most credible type of testimony during a trial.
