Barbie Latza Nadeau covered the case in Perugia. She wrote:
"From the moment they were arrested, Amanda Knox and Raffaele Sollecito were a circulation bonanza for the Italian media and a front-page staple of the British tabloids. The Italian press funneled leaks from the lawyers and prosecutors to embellish the crime story and quickly dubbed Knox 'Angel Face,' fostering a cult of morbid fascination with this most unlikely killer."

On the TLC documentary, she also said the prosecution (or maybe it was the police) "were practically handing out pictures of the crime scene" to reporters.
How so?
Amanda very credibly said it was. In her written statement to the police, she asked the police to stop yelling at her because it only made her more confused. She wrote it before she knew she was going to stand trial for the murder, so she had no reason to embellish.
