In all likelihood, Berg was working for Michael Moore anyway. Freepers have turned up evidence that indicates Berg might have been the mole that got the Abu Grahib footage for one of Moore's upcoming "movies." Moore bragged about having it on his website, although I think he's since removed those references. However, we do know that Moore boasted of having several moles getting material for him. Berg was at Abu Grahib supposedly working on towers at one time.
If someone has to be blamed, blame Michael Moore.
Angry Father Ping!
