To me (and a few others - you know who you are) Katherine looks uncomfortable in this video...
According to Sawf News, "Mann hit a jackpot when he bought the assets of Henry Vaccaro after he went into bankruptcy. The assets included a New Jersey warehouse filled with Jackson family memorabilia, which included items that could have embarrassed the family.
Mann struck a deal with Katherine under which he returned personal possessions in exchange for co-developing projects with her, starting with the coffee table book - Never Can Say Goodbye: The Katherine Jackson Archives."
I have a hard time believing Mrs. Jackson would try to profit off of her beloved son. Something is rotten.
EDIT: Please read TMZ's article titled, Showdown Between Katherine and MJ Estate.
