Dear Viewers,

Today started with "Good Morning America" -- I was a guest to discuss the OJ Simpson interview. I have received mixed e-mails about the Simpson interview taped about a week ago but will air tonight. Likewise, I had mixed feelings about doing it but I know that people are curious -- regardless of what your view of Simpson is. Most viewers want to know how he lives and how he can live with himself. Watch tonight [at 10 p.m. ET] and you will find out.   The interview is not intended to be a grilling cross examination or an endorsement of the verdicts -- but rather me eliciting information....and YOU decide. Many who have seen it are surprised by Simpson's demeanor throughout the interview. I am curious what you think about his demeanor after you see it. Frankly, sitting across from someone you are interviewing is always a bit different from watching on tv.

Incidentally my appearance on GMA was interesting to me -- despite the topic and the fact it stems from the brutal murder of two people.  I never forget that two people were murdered.  I had never met Diane Sawyer before and, of course, I am a fan of hers. She has done many remarkable interviews and I have watched them with awe.
