Don't you know the Mccanns lack of searching that night was common knowledge in PDL, so don't kid yourself.
As to the interview with Jane Hill, watch again without blinkers.
The evidence that they searched that night is in several witness statements in the PJ files. Maybe you should try reading them instead of listening to your friend - who, unless he knew the McCanns, could not have the slightest idea what they did that night. Local gossip isn't evidence either.
If you can give me a quote where Kate says she never once searched for her daughter - I'd be interested to see it. The interviewer was not talking about searches which happened the night Madeleine was abducted, she was referring to the days following when locals and holidaymakers gave up their time and spent the rest of the week searching. I see you have ignored the fact that the presence 100s of reporters - all waiting for the McCanns, would have made it impossible for them to join those people.
