What type of evidence includes photos, videotapes, and diagrams?

Demonstrative evidence refers specifically to materials that are used to illustrate or clarify testimony and provide visual context during a trial or legal scenario. This includes photos, videotapes, and diagrams, all of which serve to enhance the understanding of facts or information presented in a case. Such evidence does not directly prove facts on its own but helps to convey information that can assist the judge or jury in making informed decisions.

While expert evidence involves conclusions drawn from a qualified individual's knowledge and experience, it does not encompass visual aids like photographs or diagrams. Testimonial evidence is based on the spoken word of witnesses recounting what they know or have seen, whereas physical evidence refers to tangible items that can be presented in court, such as weapons or clothing. Demonstrative evidence stands out because it specifically focuses on items that aid the visualization of events or conditions related to a case, making it crucial for establishing clarity in legal proceedings.
