What is the purpose of demonstration evidence in a court case?

The purpose of demonstration evidence in a court case is to clarify or illustrate specific issues that are central to the case. Demonstration evidence can take various forms, such as models, diagrams, photographs, videos, or even simulations. Its main function is to make complex information more understandable for the jury or judge, often helping to visualize evidence or concepts that are difficult to comprehend through verbal testimony alone.

For instance, in a trial involving an accident, a model of the scene or a simulation of the events leading up to the incident can help clarify the circumstances, allowing the court to see how the events may have unfolded. By using demonstration evidence, attorneys can enhance the jurors' understanding, thereby facilitating a more informed decision-making process regarding the facts of the case.
