I thought about this argument and I think they would have used Gerry both ways. If he turned around and agreed with Jane they could have accused him of collusion and if he disagrees they discounted her version. Was there a solution to this? If Jane changed her tune and agreed with Gerry they would have added that to her inconsistency.
In the article I posted the problem lies with Jez as the PJ accepted his version as gospel. From their point of view there was no Jane passing Jez and hence there was no Tannerman. For the given reason Jez hadn't seen either of them.
You might have something there Rob. That the PJ disbelieved both Jane and Gerry because Jez hadn't seen either Jane nor Tannerman
They couldn't have thought it thru though. Not easy admittedly but we are getting there hopefully.
As for Jane and Gerry, they both told the truth as they remembered it.
And i think it quite likely that Gerry and Jez did start their chat in the eastern middle of the road but when a vehicle appeared they moved to the west side. The move to the west side was easier for Jez with his pushchair. This was already pointing in that directions if he had part crossed the road to meet Gerry.
