I would tend to agree, there being four possible places where a mistake may be made in each Q & A. By logical extension however this leads to the internet pundit being unsure of what the interrogator actually asked.
Couple this with the theory there is a pile of documents on the internet tainted by the hand of Levy and one is well and truly up a gum tree.
We might as well de-rig and all go home 
It is lovely for us to agree about something ... but isn't it logical that given the circumstances under which the statements were given and taken there would have been mistakes and misunderstandings?
I can't imagine the state those folks giving statements to the police were in given the shock they had all had.
They must have all been horribly aware that it could have been any one of their children who was missing.
Whether one agrees or disagrees with their child care arrangements one has to ponder why seeds of doubt about the content of police statements given under secrecy laws by them and the missing child's parents, were within hours of being given ... published in the public domain under the billing of being a "BADLY TOLD STORY"!
Who determined to impugn witnesses by not insinuating but decreeing that they were in effect, lying?
At that stage in proceedings, who had had time to collate all the statements?
Who had checked the content?
Who among the witnesses had been called back to clarify something unclear in their statement?
What appropriate investigative diligence, if any, had been performed regarding these statements.
Who released them to the press thus instituting what was to become the trial by media of Madeleine McCann's parents?
Not forgetting that Portuguese law was being flouted the proof of which was the newspaper's pejorative headline and detailed story.
The story could only have come from one source. The law enforcers who were supposed to be investigating Madeleine McCann's disappearance. So what exactly was the course of action being followed by law enforcers in the hours after Madeleine's disappearance?
- investigating the disappearance of a missing child?
- putting the first pieces of misinformation in place as part of building their case against her parents and their friends?
I think their priority was manifest and that initial newspaper headline makes it clear it was not Madeleine McCann.
