Technically, she's not being tried twice. The Italian Supreme Court threw out the result of the lower court and ordered a retrial. Same thing happens here all the time via the appeals process. OJ Simpson was in court a few weeks ago asking for a retrial of his assault and robbery charges.
She's hot, but I watched that interview she did with Diane Sawyer and I'm convinced she did it. That is one crazy psycho bitch. She reminds me of what I've read about serial killers. I think she's faking emotion and compassion because she doesn't have any naturally. Of course, I'm not a doctor nor psychologist and just armchair bull****ting with you all, but that's the way I see it.
