In my view, Eddie was a generalist and Keela was the specialist. He was meant to locate the haystack and Keela the needle. The needles that Keela found, in this case, did not lead anywhere.
The duo was an interesting combination, but, for some reason, some people seem to have assumed that if Keela didn't react (but he had) that it necessarily indicated that a cadaver had been present. Was Eddie oversold?
Yet you see the logic of pretendy burglars abducting a child!
Even if the dogs have signaled for non recuperable (bungled by FSS) forensic material to be taken to trial, the simple fact that a possible death occurred there, or a dead body was there, should be addressed and not substituted by stupid, unfounded accusations to police or fictitious burglars.
In any case, after hundreds of police people involved in the investigation, portuguese and british, it's quite telling the fact that the persecution is upon the only person that had the guts to leave his job of 27 years in order to be able to speak up.
Why would a professional leave a career, where he was considered one of the top, to be able to speak?! Because he was wrong or because his sense of justice was more important than to contribute to a huge blackout over a crime committed against a young child?!
