Dateline is using the guise of a "newly unearthed interrogation video" to draw attention to its 2-hour show on Scott's case tonite. It's the interrogation that Brocchini did at midnight the day Laci disappeared, so there's nothing new about it -- in fact, it was shown in court and the transcript has been on pwc-SII for years. http://pwc-sii.com/CourtDocs/Exhibits/P-68.htm
