Didn’t they know that Michael Moore just can’t let anything go? I think Moore is learning more with this movie out that he has to have all of his facts stocked in an arsenal ready to go at any time.
Also keep in mind that the more Moore-bashing that consists of how large or slovenly Moore looks (it’s called branding, assholes) that just means his actual message is airtight:
I bet you thought I was just going to go quietly away. Think again. I’m about to become your worst nightmare. ‘Cause I ain’t ever going away. You, on the other hand, in the face of this overwhelming evidence and a huge public backlash, have chosen to remain silent, probably praying and hoping this will all go away. Well it isn’t. We are now going to start looking into the veracity of other reports you have aired on other topics. Nothing you say now can be believed.
