She and her family followed your advice.
Italian govt is so corrupt that it makes ours look pristine. Ms Knox forgot the cardinal rule of traveling/living in any foreign country. One must avoid even the illusion of guilt.
Fortunately Donald Trump helped with the legal expenses, which I would guess went mostly for bribes. I heard expenses were around a million dollars.
I have sympathy for Meridith Kercher's family and hope that they get to the bottom of this. One person is still in prison for the crime and he was the one who implicated the others in return for a reduced sentence. His DNA was in and on the victim, if you can believe that DNA test.
Ms Knox did accomplish what she went to Italy for. She learned the language well, though at a very high price.
There is talk that the prosecutor may appeal though Ms Knox can not be compelled to return to Italy. That would keep her from traveling to any country with an agreement on extradition with Italy.
There are a number of places that Americans should not go and that number is constantly growing!
