3) there are lots of witnesses, 4) nobody denies that it happened
Trying to suggest this is like the BYU situation is disingenuous. At BYU, there was no video evidence. There were no witnesses, no corroboration. The only person directly accused denied he did anything wrong, and wasn't sitting I'm the area where it supposedly came from.
At this point, trying to continue with your narrative is nor a good look.
