The uhms and ahs are quite normal. The interview s have been transcribed verbatim. Anyone not realising they are not normal simply has no experience of transcribed verbatim statements
Not only transcribed verbatim but recorded in audio and video.
Kate describes in her book the actual process involved in her Portuguese interviews.
- questions were put in Portuguese
- an interpreter relayed them to her in English
- answers were translated into Portuguese
- and typed up by the police officer as translated to him by the interpreter
- there was neither audio nor video recording of the laborious time consuming process
And members use the result in confirmation of their notion of so called 'inaccuracies' or 'inconsistences' in statements.
In my opinion it would have been impossible were there none using that process. All it would take to introduce some would be for subsequent interviews to be interpreted by a different translator and transcribed by a different officer to introduce a poolside/carpark side ~ front door/back door misunderstood situation.
But it has all been said before many times and in many locations and it will definitely all be said again and then again in deference to Groundhog Day.
