" in his book"....gave "his book" away free did he. How is it all these serious conspiracy theorists write books about the assassination and all these other conspiracy experts have read most of these books. There is a conspiracy going on alright....and it's based on writing books about assassination.
And yet all these books, probably hundreds of them by now, have not proved anything apart from a few minor discrepancies in the case.
Obviously there is nothing new in saying people are profiting from the " conspiracy deal" but that doesn't detract from the fact that they are and as long as there is a market for these books, films, lecture tours or whatever it will rumble on.
