I did not say they cannot. If you believe Sollecito was fitted up <snip>.
And herein lies the problem. You signally fail to grasp what happened here, and why it happened. It also speaks yet again to your wholesale ignorance on this whole subject area.
But yeah, I’ll indulge you. See if anything might finally sink in.
See: nobody - that is, neither anyone in this thread nor the Perugia police and PM in 2007 - believes/believed that Sollecito was “fitted up”*. This truly has already been explained dozens of times in this thread, including directly in your direction on several occasions, including very recently.
No: the police & PM had come to the sincere - though entirely erroneous - conclusion that Knox had been intimately involved in the murder. In fact, we can be almost certain that by the early evening of 5th November, thanks to their clumsy misinterpretation of Knox’s cellphone call logs, they believed Knox had met up with a male - whom they may or may not have identified as Lubumba by that point also - and gone with him to the cottage whereupon the male had sexually assaulted and murdered Kercher.
With me so far? Good.
Now, the police had a significant problem with this narrative of theirs: both Knox and Sollecito, in their statements to police between 2nd-5th November, had unwaveringly insisted that they’d spent the entire evening/night of the murder together alone in Sollecito’s apartment. The police/PM could obviously (they assumed) figure out why a factually-guilty Knox would “lie” in such a way. But - and here’s the kicker, Vixen (so pay attention) - they then rationalised that Sollecito was sharing/corroborating Knox’s “lie” out of some sort of misplaced infatuation.
Keeping up?
The police therefore devised a plan to bust apart the “lie” being told to them by both Knox and Sollecito, so that they’d end up with confessions and “solve the case” with stunning speed and guile. Now keep remembering, Vixen, that the police and PM really had convinced themselves by this point that Knox genuinely was heavily involved in the murder, and that Knox & Sollecito genuinely were lying about their whereabouts on the night of the murder.
Still following?
So………. The first plank in the police’s/PM’s strategy on the night of those 5th/6th Nov interrogations was to *ahem* “persuade” Sollecito that 1) they knew for sure that Knox was at the cottage at the time of the murder (and that consequently she was not together alone with Sollecito all that evening/night; 2) therefore they knew for sure that Sollecito was lying about the murder night in order to protect Knox; 3) now was the time for Sollecito to come clean and tell them the “truth” about his/Knox’s “true” whereabouts on the murder evening/night; and 4) if Sollecito continued with the lie, he would find himself in deep legal trouble.
And that, in a nutshell, was how it went down and why it went down. Remember, one more time, that the police/PM genuinely thought they’d solved the crime correctly. Remember also that clown de Felice crowing proudly about the ‘skill’ of the interrogators in making the two of them “buckle” and “tell (them) what they already knew to be the truth”.
Satan knows why I wasted so much of my time writing all this. Oh well: ya do what ya can to open up the eyes of the blind, right??
* And I’m going to assume that by “fitted up” you effectively mean the police were deliberately trying to frame someone whom they either knew or suspected to be innocent.
