Thomas said today that the two Italian legislators she was with asked Knox about her earlier comments on the trial.
"She said, 'I thought I was treated well,'" Thomas reported. "I don't think she was treated well in terms of the verdict or what happened with the police. But I think she thought that she was at least treated respectfully by the people involved, by the lawyers and by the judge."
Rules of the prison visit forbade them to discuss the trial and Thomas said that while she and Knox spoke in English, "the prison guards interrupted me and said, 'You're not speaking about the trial, are you?'"
Knox said that she felt "horrendous" the night that the verdict was delivered. "She said the prison guards did come in to hold her and make her feel better. She said the other prisoners were good to her," Thomas said.
The reporter said the prison is "extremely clean." Knox's cell, which she shares with another American who has been sentenced on drug charges, is small. "It had a little bathroom with a door, a bidet, a sink, a shower.... better than some of the things I've seen at summer camp or boarding school."
The women inmates are allowed to go to a hairdresser once a week.
The prison is a new facility, just opened in 2005. The women's ward has an infirmary, an entertainment room with a pool table and ping-pong table, and a library. There is also a small chapel. Outside there is a little playground for children with benches and toys because there are cells specifically for women with children. Currently there are two women in Capanne with children.
Thomas said that when the tour of the prison ended, she passed by Knox's cell again.
"When I walked back later, she was sitting on her bed reading several pages of handwritten pages. She looked up at me. And she looked slightly more confident at that moment. She smiled and waved and said, 'Ciao.'"
