I'm confident that the translation is correct, but the judge may have made errors. That seems like a particularly large error that should have been corrected under appeal as it does seem significant.
As it stands, Amanda returned to the cottage at about 10-10:30 am. She claimed that she showered while there, but I'm skeptical based on photos taken in the afternoon. She reported to police that she saw the blood, toilet, broken window, locked door and open front door, but didn't phone anyone, not even Raffaele. She spent about an hour there, maybe 1.5 hours, and then returned to Raffaele's apt. I suppose this is when the mopping and phone call to Meredith and Filomina happened. Amanda and Raffaele then sat down for something to eat. Around 12-12:30 they arrive at the cottage? Amanda and Raffaele are standing outside the cottage smooching next to a mop - the mob that was supposedly needed to clean up the water spill on Raffaele's floor 14 hours earlier.
Somewhere in the midst of this, around 11:30 am, Amanda took the mop through the streets of Perugia but no one has come forward claiming they saw an American woman wandering around Perugia with a mop at noon on a holiday. The spill was cleaned up, the mop was back home and standing outside the front door.
The Postal Police unexpectedly arrived. Amanda had called Meredith's number from Raffaele's apt. and there was no answer so she was probably safely assuming the phones had not been found. What a surprise to find the police on the door step with the phones.
Amanda had already contacted Filomina and she was on her way. Lucky for Filomina and Meredith that the police were already there ... what if Filomina and friends had decided to break down the door anyway, even if the police weren't there (the police really had nothing to do with the decision). They would have completely contaminated the bedroom, moved the duvet, trampled on evidence. Amanda and Raffaele had already cracked the door so the next crack was going to open it.
Were they thinking: If police arrest Rudy first ... then they'll be free and clear. If Filomina arrived and not the police, evidence of Knox and Sollecito in the bedroom would be meaningless, and if Knox hadn't acted so odd, Raffaele's apt may not have been searched, and the knife may never have been discovered.
