Fuck her for ruining an innocent man's life by falsely accusing him.
The judge who let her go also explains what happened with this:
https://hellmannreport.wordpress.com/contents/reasons-for-the-decision/calumny/
The obsessive length of the interrogations, carried out during [both] day and night, by more than one person, on a young and foreign girl who at the time did not speak Italian at all well, was unaware of her own rights, did not have the assistance of an attorney (which she should have been entitled to, being at this point suspected of very serious crimes), and was moreover being assisted by an interpreter who as shown by Ms. Bongiorno did not limit herself to translating, but induced her to force herself to remember, explaining that she [Amanda] was confused in her memories, perhaps because of the trauma she experienced...
But why Patrick Lumumba, exactly? Because the police had found, on Amanda Knoxs phone, the message see you later, sent by her to Lumumba on the evening of November 1; which could also mean she actually intended to see him later to go somewhere, maybe to the house on Via Della Pergola whence the insistent questioning about that message, its meaning, and its intended recipient.
The questioning was not filmed, and was performed without an attorney present. This was a violation committed by the police which made it inadmissible at the murder trial.
She was asked questions in a language she didn't understand well, and the questions were never written out in english for her. The translator, in the absence of the required attorney, told Knox she was confused in her memories. Then the police zeroed in on Patrick Lumumba because of the message they had found.
Even then, it took a grueling interrogation, throughout day and night, and only by 1:45 AM were they able to pull something about Lumumba (who again, they had already decided on, and were now trying to get).
But let's ignore that for a second, and focus on what she actually said:
"However, it was under this pressure and after many hours of confusion that my mind came up with these answers. In my mind I saw Patrik in flashes of blurred images."
"But the truth is, I am unsure about the truth and here's why"
"Why did I think of Patrik?"
This is not what she said after the fact. This is literally what she wrote
on that very day, after hour upon hour of interrogation in violation of her right to an attorney, and in a language she didn't know well, with police already focused on Patrick because of the message.
So, while you can certainly blame her for not being strong enough to stand up to the police, you also have to admit she at least said she wasn't sure about Patrick, and only used the name after the grueling interrogation focusing on him. I give her some of the blame, but most of it in the police in that situation.
