It's also noteworthy to say that Johnny Depp was David Letterman's guest on June 25, 2009. (!!!)
What did he talk about on that show? His private island and his friendships with Elizabeth Taylor, Marlon Brando and Vincent Price, among other things It seems MJ and JD have some mutual friends, ran in the same circles. The show would've been taped shortly before the world heard of Michael's "death" - it films in the afternoon on the east coast.
Plus the question has been raised as to whether David knows something - remember his monologue when he was talking about the Oscars (?) in memory list and said something like, "you don't even have to be dead to be on it." and Michael was on the list... I actually think Dave Letterman is anti-TPTB. He's been in heated arguments over political issues right on his show and questions why his government went into Iraq. He raises a lot of good questions in the below clip and pretty much owns Bill O'Reilly, his guest, LOL. You rock, Dave!!
So Dave is aware of what's really going on and has publicly questioned it - how do "they" react? They tried to blackmail his infidelities a few years back and Dave wasn't having that so he owned up to it on his show.
And much more recently, it was claimed the Al Qaeda was targeting Dave and wanted him killed.
So it does raises the question as to what David might know, about the hoax, about the TPTB's plans, etc...
