Why hasn’t the Estate made a documentary proclaiming Michael’s innocence?

The Estate is taking the legal action for which it has a legal basis, with its request for public arbitration in the dispute with HBO. The purpose of this is to expose those involved, under penalty of perjury, for the liars that they are. Beyond that, the fans can’t – and won’t ever – know what the Estate has done behind the scenes. The Estate doesn’t always want to be publicly acknowledged or credited for what it does; all that matters is that the Estate supports the dissemination of accurate information about Michael.
