Another question. Knox had already discovered the 'burglary'; she told Filomena, Filomena told Amanda to call the police immediately at about 12.34. Sollecito called at 12.52. Why waiting for another 18 minutes?
I think the one thing we all can agree upon is that there was no burglary in Filomena's room. That was merely a point of entrance....
With the benefit of 20/20 hindsight, this is what Raffaele says about this issue in his book.
Honor Bound p. 24 said:
Of all the things Amanda did that day, none attracted more criticism than her failure to raise the alarm as soon as she saw so many things out of place
.... a criticism that Raffaele writes, was joined in with by his own family.
But Raffaele goes on to say that even he didn't think much about it. He thought, "there had to be some explanation." When he suggested they leave for Gubbio anyway, Amanda found that suggestion a "little jarring."
Acc. to him, it was Amanda's idea to return to the cottage. Acc. to him, it was on the way over that Amanda called Filomena... hardily the action of someone going back to continue the "staging", "microscopic cleaning" or "cover-up" of a crime they knew had happened, only to have been surprised by the postals!
Acc. to Sollecito, despite Filomena's sketchy English and Amanda's sketchy Italian, the clear thing was that Filomena wanted Amanda to go back to the cottage to check things out. Filomena had promised to be at the cottage "within the hour."
When at the cottage, Amanda received a call from Filomena. Once again, the issue of the timing of the 112 call is a little immaterial. It was clear that Amanda was raising the alarm and that Filomena was, appropriately, ALARMED!
Such is the nature of the factoid of the timing of the 112 call - that Crini dropped into his summation about 3 1/2 years after anyone, but factoid-guilters, thought was important.
