Thanks for posting this, I was wondering if the interview story was just rumor. Now I know it's not. And, as has been said before about this whole situation, curiouser and curiouser.
From the article: Moore's terse statement said[:] "It was approximately 20 minutes long. We are not releasing it to the media. It is not in the film. We are dealing privately with the family."
OK, I can understand why they wouldn't release it to the media, who probably wouldn't play it anyway unless it was filled with invective against Bush, which I guess it isn't or it would have made the final cut for the movie. But, don't they have an obligation to share this with law enforcement? Remember the advice of a million murder mysteries: the way to solve a murder is to examine the victim's life. If I were investigating Berg's death, I'd want to talk to Mr. Moore, and see his interview footage ASAP.
