I live in Amanda's home area, and in these parts it's not popular to say you believe she is guilty. I do know that the Italian prosecutor of her first trial is a very strange man who is know to have flubbed many cases.
I don't think Amanda is guilty of participating in the murder. I think she's guilty of being a spoiled, thankless girl who was living it up big in a foreign country on other people's money. I think she failed to realize or care that she has lead a very privileged life, and it appears to me that her advantages have not meant much to her.
Her real guilt, I think, lies in engaging in a very self indulgent culture in which another person's life meant little. I think she drew in an element of people that put her and her room mate at risk. And then when her so-called 'friends' did their worst, she made no effort to help her room mate. She took a lot of risks, and her room mate paid the price.
But no one would dare say anything like that around here!
