I thought the Spier correction made it sound truthful to. If there were embellishments I think give him a break, it's hard to remember... he wasn't taking notes thinking this girls getting abducted tomorrow. But because he found out about it all quite soon after the job, he may have implanted the guys face in his mind well enough to say if it was BRE or not. Although it wasn't recorded on the system, he may have picked Sarah up a 2nd time with the taxi being booked under a friends name. I think police had so many calls that they would have been trying to pick holes in stories rather than looking between the embellishments or confused memories to work out the real scenario.
Actually I was looking into this story at the same time as others yesterday too... I went on a tangent from reading the Droc stuff, wondering if these stories crossed paths. Could match up I guess. What do others think?
