Some semblance of normality and reality and rationality would explain people shouting when half the town was out searching that night! searchers are on video saying this is exactly what was happening, people were shouting left right and centre to each other
I agree, and so the 11pm sighting is likely to be two searchers, discussing briefly how bad the current situation is, that no-one has found her yet, and where to search next. If the witness does not understand the foreign language English and maybe is not aware yet that a child is missing, it would be easy to misinterpret a discussion between paniced searchers in the street. I think that is what it is, two completely innocent searchers desperately searching.
Sorry I can't remember which 2008 UK Rog statement it was in, but it was two members of the holidaying group whose search paths happened to cross. I just noted that the location is close to the location mapped on TV. Even it is the same, it simply means that people were genuinely desperatly searching (and also that SY don't have the same knowledge of the layout of the town as lowly forum posters and might have had the innocent answer in a file on their shelf already). It might be a different pair of searchers, I don't know.
