I happened to tune in to 20/20 last night as it was starting, and the lead segment was Barbara Walters interviewing Mary Kay Letourenau. I watched about 5 minutes of it before I became physically ill and turned it off. It was disgusting.
The whole tone of what I saw was Mary Kay acting the poor victim - "My marriage was bad, blah, blah, blah." "We had an emotional attachment to each other, yada, yada, yada." SHIT!
Barbara was of course, comforting, etc. I was yelling in my mind at them both "Bitch, did you ever think for even a nano-second about the permanent scaring you're doing here, or was it just all about you!"
If you can stomach it, here's a link to the interview: Barbara Walters interview of a pedophile
