I watched a fair few of the workmates testimonies. Can’t remember which one but when she was asked about the French subs, she just dismissed that staffers would be talking about anything important at the pub. The whole premise that he would be writing such notes at 2 in the morning is rubbish IMO. As another pointed out, they were all hooked up remotely. You would get the keys and piss off home, surely? The current trial has left me with more doubts, now that I have listened to other people.
