The admissibility of the inevitably increasing amount of digital evidence to the world's courtrooms may be one of the keys to the preservation of global justice. Digital evidence can take many forms, this paper will concentrate on both graphical evidence presentation technologies currently in use (such as forensic animations and interactive environments) and potential future applications (e.g. the introduction of more pervasive computer devices). Technologies utilising Computer Graphics (CG) and Virtual Reality (VR) for evidence presentation can have great persuasive powers. These can be perceived as a benefit in increasing the understanding of complicated technical information to a generic audience, or as a threat to justice introducing potential bias and prejudice.This paper describes some cases where CG and VR evidence has been previously admitted to courtrooms. It goes on to discuss the various factors affecting the admissibility of current digital evidence forms on a global scale and concludes by introducing new technologies which may have worldwide potential in the field of forensic evidence presentation.
