Great thought, but the AAIB report may not necessarily be submitted as evidence in any case and the members of a jury do not generally know what case they will be called upon to judge before they get there. So, no, most jurors don't have time to read up on a case in advance.
I doubt more than a small percentage of the U.K. population will ever read the full AAIB report when they can get all they think they need to know from the Daily Mail. They will more likely be influenced by the almost daily presentation of "facts" in their newspapers without knowing where those "facts" came from.
