You’re claiming that it’s all entirely trustworthy?
The counterpoint to that would be that the BBC didn’t know the narrator was the son of a prominent terrorist and that others involved also have apparent links to Hamas.
You don’t appear to have a counter argument to that.
How am I, a non-expert, supposed to pick up on factual errors in a documentary? I am supposed to be learning from it, not fact-checking it. The important thing for a documentary viewer to know is if they can trust the source.
I don’t appear to be able to trust the source and you don’t appear to be able to offer any reassurances.
