The PJ were only interested in a reconstruction of the T9's movements. If the various external witnesses were so important, why were they not also interested in bringing them back as well?
Whatever software the Met use, it can presumably work out the various permutations.
Some people are bound to give an approximate time unless there is a particular reason to note or be able to verify the precise time. There was no CCTV to check, but once the alarm had been given, there were phone records of the staff calling each other to put the missing child protocl into action.
Too right they were. A few would have used their watches thank god and others just listened to what the loudest said. There's a big difference.

078 'Okay. So take me through from there then, what happened after that''
MO 'So, erm, back to the table, erm, we have, oh, back to the table, Gerry got up to go and, to go and check on his kids, I mean, and I'd come back and said, you know, I didn't hear any noise when I listened outside your room, so I thought it was a little bit odd that, you know, not kind of a wounded pride that he sort of didn't trust me, but, erm, I just thought, oh, you know, I've just checked you don't really need to check and sort of, you know, sort of go back, but, erm, he sort of got up and went back to check on, erm, on his kids."
4078 “What time would this have been around?”
JT “I’d say it was around
ten past nine’ish”.
1578 “And at what time”'
ROB “So about
twenty five past nine I left the table”.
ROB "I returned to the table about
quarter to ten”.
The guest returned, at about
21.45. (Waiter who served ROB's steak -Ricardo Alexandre da Luz Oliveira)
Rusell said he returned at 9:45 (corroborated by the waiter who served his steak) NOT 9:55 as on the timeline named GERALD. Matt has disappeared from that check. There's a 10 minute discrepancy like I said and that is proved from English recorded interviews (No translation excuses!). My timeline is spot on and can reveal who did it, when and how. It suggests why the timeline has changed 10 minutes to rule somebody out of a sighting. SY should have no problems if they have truly done a forensic examination of the timeline that night. You cannot escape the truth.
