I am not totally convinced this was a credible sighting.
I can't get past the fact that he didn't immediately report it, knowing he was surrounded by people searching for the child, he just supposedly saw being driven away.
If he is a 'credible' person, why would he wait for officers to come to him?
And why go to a night time social event and 'mention it' [<<<the words he used] to the sister inlaw of an officer?
I just can't put all off that together and see him as a credible person. Now he says he is 100 percent certain that was William. If that is true, why didn't he go to the proper authorities as soon as he was aware it was the missing child?
None of his explanations have sounded reasonable, imo.
I agree that it's very hard to view RC's evidence as credible. I can't fit RC's sighting into any of the possible theories about current POIs that we are aware of. The top of my list at the moment are PS and FA, and RC's evidence just doesn't fit nicely into the possible scenarios for me.
