You're analogy is insane, Backes. They were different documentaries but they were, supposedly, the same footage of an event that only happened once. 

And even if you assume that they were derived from different cameramen filming the event, which you don't know for sure, the two cameramen would have been so close to each other, and so entirely subject to the same conditions, that any differences in the films would have been negligible at most. Undoubtedly, we should be seeing a high degree of correlation between the two. And no assumptions pertaining to different cameramen can possibly explain this variance:

They are different men, Backes. Absolutely and positively. To even suggest otherwise makes you a blood-soaked Kennedy-killer.
