Well that may be coming from me. The issue is the time line. There is a timeline on PMF. There is another timeline which comes from head of homicide:
10:40 PM RS + AK arrive at police station for RS to be questioned. He goes in
10:40 PM - 1 AM AK is waiting does her cartwheel, backbend and split
1 AM -- Police determine incorrectly that RS shoe matches bloody footprint and arrest him.
~ 1 AM Napoleoni goes to the vending machine to strike up a conversation about murder. She does not intend to allow Amanda to leave. Napoleoni takes Amanda back to interrogation room
1:45 AM Napoleoni calls in translator and logs Amanda as a suspect. Does not start taping as she should.
1:45- 3:30 Napoleoni turns up the heat. Confronts Amanda about her about text messages. This is when Amanda says she was cuffed twice, called liar.... This is also when Napoleoni says Amanda struck herself.
3:30 Mignini called in.
?? Mignini takes written statement.
5:45 AM Amanda signs police statement
This doesn't agree with the PMF timeline but it actually makes sense.
Ah, the tea and cookies timeline, the one Monica Napoleoni--who's something of a
hottie incidentally-- and the other two female officers gave in court. I can't help but note it doesn't match very well with much of anything else, although you posting it did remind me that Raffaele's statement was given at 10:40, for some reason I had gotten it into my head recently that it was 9:40.
It's interesting that in this version we get the impression that the interrogation is merely a nice little chick chat. As I recall, Amanda quickly breaks down when they go through her phone list and 'accuses' Patrick out of the blue for them, after of course plenty of time for the interpreter to be summoned and her to be made a suspect before they even start this friendly little 'interview'--just like it says in the book. Of course it's damned odd that this version doesn't correspond with the time we do know for the first statement, 1:45, she's spent so much time going by the book here and all. It's really kinda weird there's only one statement given in this version too...
Being as she's been so nice about it all, certainly we should forgive her for that minor error of accidentally forgetting to turn on the cameras, shouldn't we? She was just shocked...
shocked to hear Amanda 'accuse' Patrick out of the blue like that! Later on she's going to 'risk her job' to make sure Amanda gets something to eat, how could anyone think anything untoward about her little mistake?
Another thing about the tea and cookies chick chat version is it doesn't explain why there's twelve cops eligible for the calunnia charge. Of course when she gave this testimony no one knew there would ever be one...

For others I'm adding the PMF timeline for contrast:
Nov 5:
2. 1700 Raffaele summoned to the police station. Amanda goes with him and waits in a separate room.
3. 2000 Candlelight vigil for Meredith.
4. Raffaele "breaks."
5. 1040 (at the earliest - Amanda is talking to Filomena about where to live at 1039) Amanda is called in for formal questioning
Nov 6
6. 0145 Amanda becomes a suspect and the interrogation is halted
7. 0545 Amanda (who still has no lawyer) asks to make a spontaneous declaration. In it, she accuses Patrick Lumumba of the murder and claims to have been in the kitchen while Meredith screamed
8. Amanda & RS jailed; police arrest Patrick
9. Amanda writes a spontaneous testament, in which she claims to have spent the evening with Raffaele, but still confusingly writes: "I stand by my statements that I made last night about events that could have taken place in my home with Patrik, but I want to make very clear that these events seem more unreal to me that what I said before, that I stayed at Raffaele's house."
10. Police chief wrongly declares "Caso Chiuso"
In fairness to them, that hasn't been updated in a long time, they abandoned the timeline idea completely. However, outside the first entry it seems to correspond better to everything else than the first story.
