The McCanns took to Luis Neves more than they did to Encarnacao;
He seemed intelligent, personable and strong, open to suggestions and new ideas. My initial impressions of him were all positive. Iwrote in my diary that night: A good fella; on the ball; humanitarian, sensitive. [madeleine]
Then, on 8th August 2007 the two men decided to interrogate the couple;
Neves stated bluntly that they didn’t believe my version of events...’ I was in no doubt now that they were trying
to make me say I’d killed Madeleine or knew what had happened to her...In a slightly threatening manner, Luís asked why I wasn’t looking him straight in the eye. There was no reason, other than that I was incapable of looking at anyone properly: my own eyes were so swollen and sore that I was struggling to keep them from closing
completely [madeleine]
Outside the police station we were surrounded by the press. There was no need to ask how they knew we were there. [madeleine]
So according to Kate McCann then the now (2019) head of the PJ interviewed people he clearly saw as suspects and asked them questions which should only be asked of arguidos and without them having a lawyer and interpreter of their choice present.
What a pity she can't prove it happened; the interview wasn't recorded, the media didn't manage to even get a photograph and she doesn't seem to have complained officially about this breach of their human rights.
