Hard pressed after two hours of questioning as a witness shortly after dinner and with a year of work and a year of university under her belt?
Amanda was no naive child. She finished high school, took a year off, then completed a year of general studies at the University in Washington and then found herself in Germany. She blew off a gov't job that her uncle arranged for her because it was boring. She pretended to be sick for the next two weeks, living in the apartment that was attached to the job, getting stoned in the park and doing who knows what on the train to Perugia ... ciao sucker to her uncle. That's Knox before the murder. She was all grown up.
Fast forward a month, she's hooked up with just the right guy, it's the Day of the Dead, her roommate is murdered, and she's suffering lapses of confused imaginings or dreamed realities, telling whopper lies and has no alibi.
It didn't seem real that she was landing in Seattle. The scream and murder were described in her statement, but when she had to explain herself in court she claimed that the scream and murder didn't seem real. Whata a gal! At least we know that when she says that things don't seem real, they are real. She did land in Seattle, even though it was no more real than the scream and the murder ... for Knox and her confused imaginings and dreamed realities.
