Not sure what you're getting at Alice.
The UK rogs were verbatim (both of interviewer and interviewee). Presumably some admin staff was tasked with wading through the recording and typing up every utterance.
The PT statements weren't verbatim at all (and therefore don't fit into your Item 1, point 2 category.)
My impression (not sure how often one has to repeat IMO) is that in the early days at least, it would have been the
interviewing officer typing up the report as the answers to his / her questions came through via the interpreter.
Many statements include phrases of the type (paraphrasing) "Questioned, the witness stated...".
I accept the bit about T7 interviews.
I was just delineating the two sorts of transcripts covered by the CPS. I wonder why they didn't just use a sealed security bag to send a copy of the recording rather than have a transcript?. PT law allows for that.
The other bit is about how confusion may be sown without really trying.
In my example what all three translators/interpreters should have written/said is:
The standardisation of length is effected by the use of slip gauges [block gauges would have been an acceptable alternative].
Slip gauges aka, block gauges, Johanssen's gauges, Jo-blocks and in the NE Jo-slips.
What the interviewee would have said is:
The standardisation of length is effected by the use of
Jo-slips. [the use of the term makes him from the NE in all probablity]
In the NE when some one says "Jo" you hear something like "Jew".
So the interpreter hears: "The standardisation of length is effected by the use of Jew-slips"....off it goes!
Then you need something like an 80 year old Geordie machine tool fitter to unravel it for you.
Googlish version of what the interpreter thought he heard.
The standardisation of length is effected by the use of Jewish guides.
The standardisation of length is effected by the use of slips of Jews.
Standardisation of length is achieved with the use of jew bottle.
