"Crosstalk" means there was more than one person talking at the same time. Therefore, transcriber couldn't transcribe it. Too many people talking at the same time.
Nothing sinister in the transcribing at all.
Yes, I know what "crosstalk" is. I'm not a dummy, as you seem to indicate. It still gives them an "out."
And I do find that transcripts are very often incorrect regardless of the "crosstalk" trump card.
