Notice the breaks when they change camera angles. Those are probably times he messed up, so they started over in his script from that point. Why else would you change camera angles on a recording, or have multiple cameras on a recording?
There was just a jump toward the end in the straight-ahead camera angle where they cut something-- another mess up by Monson. His head jumped about 2 inches instaneously where they cut something.
Perry is nearly as hard core as Packer, in some ways. Both Packer and Perry are/were opposed to the writing of "honest" answers to issues, such as JS poly, multiple versions of the 1st vision, etc. Better to just leave it alone.
They are all really in a bind here. Nowhere to go. Answer the questions with a lie, they will be called on it. Answer truthfully and open a can of worms by allowing that there really are issue, do nothing and it festers. Screwed no matter what!
