Yes, and kudos to Grinder for coaxing this admission out of Machiavelli.
But of course, it's been obvious from the beginning that the "witness, not suspect" meme is unsupportable. The regular PGP claim is that Raff withdrew Amanda's alibi during his own interrogation, which was when the police called her in to the interrogation room. This obviously can't be squared with her not becoming a suspect there and then.
Briars, of course, is ignoring this and trying to convince us that an opiate abuser can still be a credible witness. Briars points to the ISC ruling as bringing sanity to this issue! Others would think it brings the ISC into disrepute, looking like it wants to convict two innocents
against the evidence.
For some reason, Briars does not get this.
But back to your point. The timeline is not that Raff withdrew Knox's alibi, and THEN they took Knox into interrogation.
They brought Knox into interrogation at 11:30 pm based on Knox's lie about Meredith's drug use, and the general use of soft-drugs in the cottage. For the record, Sophie lied about this too, and Laura cautioned Knox about being too honest about it as well. (No wonder everyone turned on Knox afterwards.)
The point being, that they brought Knox into the room based on the issue of the untruth about the cottage and marijuana ... THEN the cops checked her phone and zero'ed in on the text message, "See you later". It is unclear if the cops erased Patrick's incoming message saying, "Do not come in, there's no work tonight."
By all reports it was a double whammy the cops aimed at Knox, the second of which was the "withdrawal of the alibi", that Napolenoni herself brought into Amanda's interrogation room, fresh from Raffaele's room. (Classic playing one off against the other.)
Strangely, IIRC, Raffaele says this happened later in the morning... towards 3:45 am.... but I am pulling that time from memory and am open to correction on what Raffaele said.
If there is ANYONE PGP or PIP who says that it was Raffaele's withdrawal, THEN she was called into an interrogation room, then they have to review their timeline. That's not the way it happened. Acc. to Raffaele, he didn't even really withdraw the alibi, he just said he could not remember what occurred Oct 31 as opposed to what occurred Nov 1, and when he asked to consult a calendar, he was denied. The cops wanted his memory fuzzy.
Napoleoni did not take into Amanda's room the withdrawal of an alibi, so much as that she took into the room the fact that Raffaele could not remember, and was denied the tools so that he could remember.
You see, the point of interrogation is patently NOT to put together a timeline. It is to get them to confess. This needs to be stressed. The goal is confession. Putting together a timeline is for later.
The point of pressing Raffaele to remember is not to have him actually remember, otherwise they would have given him the tools to aid memory. The point is to get him to say something that they can then take, outside of the context of the way Raffaele put it, into Amanda's room to use as leverage on her.
The goal is confession. How you get there is to be sorted out later.
Everyone needs to read up on this, because the point always gets lost.
