Rethinking the use of warnings with transcript and video evidence in trials
New research examining the impact multiple forms of evidence has on juror perceptions during criminal trials has found the use of video material could be detrimental without the use of a judicial warning. Ref. Source 2h.
Any and all evidence submitted in a jury trial should come with a warning so the jury does not have a skewed perception of the evidence. Sometimes listening to the trial again can help you see something more clear but with video evidence of the trial I think it will not help that much as emotions can be staged and cause the jury to be biased.
