We know Amanda Knox and her boyfriend's DNA were found on the murder weapon, despite their feeble attempts to bleach it off. We know Amanda Knox lied about her whereabouts on the night of the crime. We know Amanda Knox falsely claimed her boss committed the crime. We know Amanda Knox changed her story about the murder at least three times. She has no satisfactory accounting whatsoever for what happened that is actually consistent with other witnesses or the forensic evidence. None.
She's pretty for a few superficial millimeters outside, but inside, she's a scumbag murderer. And if you're defending her, so are you.
