Most of those were probably the producers updating and editing and fixing it as best they could...and then their family and friends.
It would be interesting to know what materials and sources they used in putting together the report.
For example the video tape you mention.
Based on what we heard from Col hunt....There are likely multiple copies of the video tapes from the various command centers.
If they are editing a tape and passing it off as unedited....I imagine that will be exposed at some time.
