Have now watched three quarters of tape 2. I really couldn't take any more.
Basically, Amy Tierney is a deceitful liar according to Hall, although he doesn't seem to have been able to come up with a reason why this lady would lie through her teeth - so extensively - for a couple she didn't know. Surely discovering the reason for such duplicitous behaviour by Amy Tierney would be a priority - as without a reason for it - it makes no sense.
He also can't understand why as a mere nanny she was at Reception on 3rd May. She was in fact Head of the Baby Club and Mini Club and was on duty. She was also involved in the Missing Child procedure AFAIK.
The usual nonsense about photos is covered - ad nauseum. Mr Hall thinks the proof that the' last photo' was not taken on 3rd May is because Gerry is pale on that piccie, but tanned in the piccie on the following night when he and Kate spoke to the press. He seems not to have noticed that in subsequent photos (like the one with the other man holding a bag of shopping) taken on the 5th May - Gerry is the same colour as he was in the last photo taken by the pool.
It seems to me (so far) that Mr Hall has not read too many of the files himself but has relied on information from sceptics such as Pat Brown, video maker Heidi ho, Tony Bennet and others. That says it all really IMO.
