What would upset me more than "The trick is knowing whether the errors were significant" is "The trick is knowing whether the errors were deliberate".
If Robert Murat was involved he would surely have inserted deliberate errors into the translations he completed. I read that they didn't find any examples of deliberate errors.
I disagree with that hypothesis, Robitty. In my opinion any translator would have been aware that statements could have been easily checked for deliberate translation errors.
Therefore in my opinion if initial errors were made they were inadvertant.
Were an individual so inclined the value to anyone involved in Madeleine's abduction would have been the knowledge of who had seen what, where and when. Great way to keep one jump ahead.
In the event I think Robert Murat was genuinely eager to help and just got caught up in a maelstrom partly because, in my opinion, of his own rather eccentric behaviour.
