Let's imagine the hypothetical question before Amanda's arrest:
Police bully: Amanda, we know you and Patrick were there at the time of the murder. We know that Patrick murdered Meredith. We have found physical evidence proving that Patrick murdered Meredith, and we have also found physical evidence proving you were there too. So you must be confused about where you thought you were that evening. Sometimes people who have been part of a traumatic event involuntarily blank out the event from their memory. This must be what happened to you, Amanda. Now you must try to remember. You must try really, really hard. And remember, we have proof that you and Lumumba were there, so be very careful about what you remember (cue "Police Interpreter" who actually becomes part of the interrogation team to coach Knox about the existence of traumatic memory loss). So, let's be perfectly clear here Amanda. You need to recover your lost memory, and tell us what we already know. By confirming that you took Patrick to the cottage and were present when he raped and killed poor Meredith, you will give us additional evidence against this brutal killer. So, do you remember the truth now Amanda?
Knox: But I remember being at Raffaele's apartment that night.
Police: But Raffaele has just told us that he now thinks you might have left his apartment for an extended period that night. Face it, Amanda, you were there and you took Patrick there. You might sincerely believe that you were at Raffaele's all night, but we have proof otherwise and Raffaele himself now supports our position.
Knox: Uhhh, this makes no sense, I don't know what to think.
Police: Oh and by the way Amanda, two more things: firstly, if you continue to insist that you were nowhere near the cottage, this will count against you in subsequent court proceedings. If, however, you now remember the truth, this will be very much to your advantage. Basically, Amanda, if you continue to insist you weren't there at all, we'll have to assume that you have something big to hide, which is that you were actually directly involved in the murder. And any court would take that position too: you'll go to jail for 30 years Amanda. And secondly, by telling us the truth - that you were there but that Lumumba killed Meredith - you will be protecting yourself as well. After all, Lumumba knows that you know he murdered Meredith: he might therefore try to get to you to silence you. Why do you think he "bumped into you" outside the university the other day? We suggest that your safety is in grave danger unless you cooperate fully with us and help us bring Patrick in immediately.
Knox: Uhhhhhhhhh, I don't know what to do or what to think.
Police: Right, enough messing around now Amanda. Start remembering what happened that night, or you'll probably go to prison for a very long time - that is if Patrick doesn't get to you first. Remember, we have solid evidence placing you in the cottage at the time of the murder. So we must be right, and you must had suppressed your memory. Now is the time to tell us everything: that you met up with Patrick and went to the cottage with him, whereupon he attacked, raped and killed poor Meredith while you were in another room. Shall I draft a statement to this effect, Amanda?
Knox: Uhhhh yes, you must be right. I must have been there. Yes, I'll sign whatever you want.
