Do you think the defense (BP Union) has a copy?
No... I don't think anyone has a full final copy.
I've seen no reports to conclude otherwise.
I have seen a lot of reports, quoting testimony. I can only conclude that they are based on accounts of those in attendance at the trial. Those that were reported from March and February carry more weight than those after-the-fact accounts--until the full transcript is available to the parties and the public.
