It is clear that Berg was working for Moore. He took a lot of Moore's footage and turned up some really great stuff. Enough stuff for another two or three really, dramatic flicks. No, really!!
But Berg (and this is the part that the investigators will find; Moore has video tapes and taped calls and emails) wanted a much bigger cut, a share and not the salary that Moore hired him for. Moore had(has) the stuff in a can; Berg threatened and enlisted his family in Philadelphia. Moore saw an easy way out and dropped a dime on Berg.
Moore paid some Iraqi killers, folks he knew through his anti-American contacts in France, to kill Berg and take him out as a financial threat. The father would never accuse Moore if it meant missing a shot at Bush, so Moore is home free.
But, it just isn't right to out a celebrated movie hero and talk of his murder of Berg. As a movie legend, Moore deserves, well, more.
God...you're funny!
