Definition - What does Demonstrative Evidence mean?
Demonstrative evidence is any evidence besides testimonies that can be used in a trial to demonstrate a point. Demonstrative evidence can include items from the scene of the crime, other items, charts, pictures, etc. Attorneys use demonstrative evidence to support their case and help prove the legitimacy of their claims to the judge or jury.
Justipedia explains Demonstrative Evidence
An argument by itself in a trial is typically not as compelling without evidence demonstrating its legitimacy. This is why many attorneys use demonstrative evidence. For example, if an attorney is trying to prove the point that a defendant is guilty of drunk driving, then he or she may use demonstrative evidence such as the police report from the incident with the results of the driver's blood-alcohol content level written on it. Such demonstrative evidence could strengthen the attorney's case significantly.
