What could potentially undermine a witness's credibility during testimony?

Becoming visibly upset or out of control during testimony can significantly undermine a witness's credibility. When a witness displays strong emotional reactions, such as anger, crying, or other forms of agitation, it can raise doubts about their reliability and the accuracy of their account. Such behavior may lead judges or juries to question whether the witness is truthful or merely trying to elicit sympathy or distract from the evidence. Credibility in court relies heavily on a witness’s ability to present themselves in a calm and composed manner, as this fosters trust in their testimony.

In comparison, being overly cooperative may actually enhance a witness's credibility, suggesting that they are willing to collaborate fully with law enforcement or the judicial process. A lack of understanding of the legal process may affect how well a witness can articulate their testimony but doesn’t necessarily discredit their account. Providing consistent answers is typically seen as a strength and fosters confidence in the authenticity and reliability of the witness's statements.
