But that's not the way she told it.
If she was untruthful about that, why should anything she said be believed ?
I know its not the way she told it but if she did what I'm suggesting she had no idea at the time her movements from tapas to 5D would be placed under the microscope. With the benefit of hindsight T7 must realise the decision to leave the children without any sort of supervision while they wined and dined at tapas every night was a disaster. Worse still at the very least the McCanns were leaving the apartment unsecured and in the case of JT/ROB leaving a child who was unwell and at some stage vomiting. If on the Thu eve JT/ROB were exiting/entering 5D via the back/alley/unlocked patio door they might have thought a damage limitation exercise was called for and said they were exiting/entering via the locked front door overlooking the car park.
GM claims when he was talking to JW he was standing around the entrance to the alley but on the opposite side of the road.
JW claims when he was talking to GM it was outside the small gate to 5A.
JT claims when she observed GM and JW chatting they were outside the small gate to 5A.
If GM is correct I guess its possible GM and JW did not notice JT pass the other side of the road.
If JW/JT are correct I can't see how JT passed them and they did not notice.
So taking all of the above into account imo I think the most likely scenario is that on the Thu eve (perhaps due to the situation with EOB) JT/ROB were exiting and entering 5D via the alley.
