...even if the video was viewed by the LEOs before and/or during the time those reports were written?

That is correct. Unbiased moving pictures of the scene are awfully hard to refute. What the video DOES NOT display is motive. That will be determined at a later date.

Which is exactly why they should NOT be viewed BEFORE the reports are written. As "trained observers" LEOs should have no need of these moving pictures.

What the video DOES NOT display is motive.

..UNLESS their reports would conflict with the moving pictures in a way that would demonstrate motive.
