What function does demonstrative evidence serve in a trial?

Demonstrative evidence plays a crucial role in a trial by helping to illustrate facts and clarify the understanding of the evidence presented. This type of evidence includes diagrams, maps, photographs, videos, and models that visualize and explain the circumstances surrounding the case. Its primary function is to aid jurors and the judge in comprehending complex information, making it easier for them to grasp the context and relevance of the case at hand. This visual representation can significantly enhance the overall persuasiveness of the arguments made by either side.

While witness testimony certainly provides a personal account of an event and is vital to establishing facts, it does not serve the same function as demonstrative evidence, which is specifically designed to clarify and visualize information. Similarly, while some evidence may serve as primary proof of a claim, demonstrative evidence enhances existing evidence rather than being the foundational proof itself. Lastly, assessing the credibility of witnesses is specifically about evaluating their trustworthiness, which is distinct from the illustrative role that demonstrative evidence plays in the courtroom.
