Immersing the jury in the scene, in 3D, can only enhance their understanding of what went down. While transporting jury members to the actual crime scene might be expensive, difficult or even impossible (arson) – a 3D recreation might be affordable and achievable in the future.
Once again I quote Infinite Reality ( by Jim Blascovich and Jeremy Bailenson), this time from page 202:
Lawyers and judges can also use virtual reality to enable jury members to experience a crime or accident scene “firsthand.” Unlike a two-dimensional map, chart, or another audiovisual aid, such as a photograph, jurors can enter a re-creation in virtual reality. Jurors can experience the visual perspective of any person who was actually at the scene. Furthermore, they can move around and experience the environment from any point of view. We have worked with the Federal Judicial Center to help them use virtual reality to study how reconstructing crime scenes digitally can improve eyewitness identification via “police lineups.” Compared to witnesses looking at suspects’ photographs, which is how 151 approximately 75 percent of police lineups occur in the United States, a virtual sequence of suspects embedded in a re-creation of the crime scene itself can improve eyewitness accuracy. A witness wearing a head-mounted display and walking among the avatars can see them from novel angles. Moreover, she is able to get extremely close to their heads and faces—something actual witnesses are not only prevented from doing but are often afraid to do. If the crime occurred in a liquor store, the witness could view the lineup in a virtual re-creation of the liquor store without ever having to physically return to the scene of the crime. This is particularly useful for witnesses who would be traumatized by a return to the actual crime scene, or when the crime scene no longer exists (as is often the case with arson, for instance).
