The FBI did not do a ten year investigation. They provided administrative assistance to other law enforcement agencies in their own separate investigations.
Things that were found in Michael Jackson's house during either the 1993 raid or 2004 raid:
-a collection of soiled diapers
-a photo of a fully nude Jonathan Spence, who refused to testify in the 2005 trial. Jackson was not charged because photos of nude children not engaged in sexual acts are, for some reason, considered legal
-several "art books" containing fully frontal nude photos of young boys
-several photos of Kendall Cunningham and his brother from the waist up, shirtless, in provocative positions
Not to mention:
-he admitted publicly that these children slept in his bed
-he brought these children on tour with him and shared a hotel room without their parents
Even if you believe the two accusers from the documentary are lying there's still:
-Jordan Chandler, whose family Jackson paid 23 million dollars to shut up
-Jason Francia, whose mother worked for Jackson as the only maid allowed to clean his room
-Terry George, who claimed Jackson made sexual phone calls to him BEFORE any other accusations came out
-Gavin Arvizo
-Star Arvizo
-Michael Jacobshagen, who has this book:
Which is another copy of the same book that was taken out of Jackson's bedside nightstand. Jacobshagen's copy is inscribed by Jackson himself:
You are a fucking simpleton.
