These statements are untrue. Unless you can provide Cites. If not, I shall be deleting this comment.
Note the word "reportedly" in my post...
Here's how Amaral reports it in his book:
JANE TANNER FORMALLY RECOGNISES ROBERT MURAT
Before the search, we want to assure ourselves that Jane Tanner recognises him as the individual she saw on the night of the disappearance. She is sitting inside an unmarked car, whose tinted windows allow her to see out without being spotted. The vehicle is parked at the exact spot where she was on the night of May 3rd. Robert Murat, anonymous amongst plain clothes police officers, goes up the road in the same way as the alleged abductor. Jane Tanner is adamant: it certainly is Robert Murat that she saw that night.And here is where it is reported that it was definitely "George" she saw.....
