I guess the whole question of her accusation of Lumumba, and whether, ethically speaking, she owes him the apology he has repeatedly requested, hinges on whether she can be held responsible for what she said or whether the treatment she received from the police caused her to have temporary false memories, which I believe is how she explains it? (Trying to be careful here - happy to be corrected if anything I say is unfair, offensive or factually inaccurate).
Unfortunately I guess that's an impossible thing to conclusively prove one way or another, as nobody else can see inside her head.
I do have a little experience of a similar phenomenon (trigger warning on what I am about to say, CSA related). I used to do work with survivors of ritual abuse, and some said that they had witnessed the impossible (presence of Satan etc). And I absolutely believed that they believed this, or previously believed it (when I spoke to them most were at a point where they understood the "memories" were implanted.)
What these survivors had in common was that they had been subjected to sickeningly extreme physical, sexual and emotional torment over a very prolonged period of time.
I'm not sure it's possible to know for sure whether Knox actually had false memories implanted by her abusers (in this case the police) or not.
What I am confused by is why she allowed this scene to be presented in the way it was in the ITV drama. As what is shown there is such a minimisation of the level of psychological torture needed to induce a false memory (as I understand it) that it's possibly even offensive? Shortly before the interrogation scene, she is shown flirting with an attractive policeman in the waiting room and showing him some yoga moves - she appears entirely physically and mentally healthy and in control. Then in a short space of time in which a few people shout at her, she appears to be lightly struck twice (any police violence is totally wrong obviously, but it's really minimised), and the translator makes maybe one comment about the possibility of repressing things...suddenly she "sees" Lumumba. To be honest, that bit looks like it's more of a lightbulb type moment in which she thinks "I know, if I blame him they will stop shouting" than any kind of implanted memory....
And this is something that confuses me about Knox generally (and I really hope nobody finds this suggestion offensive) - I sometimes wonder if she actively courts negative opinions at times, deliberately portraying herself in a negative light. A lot of the ITV drama felt like that. And her very choice to make a comedy show, when she could have perhaps just promoted her show as a lecture or Q and A or story-telling show or whatever - to me feels like this too?
