I don't think they are necessarily ignoring them. I think it's somewhat confusing when you have other players saying they were there at the time of some of the accusations involving players and that the accounts were not the same. Whether right or wrong, I understand how some would question this, and this doesn't make them trolls.
Since I haven't seen the video of the encounter with the trainer, but I trust that the university HR department handled this as it should have within the established rules of conduct. It would have been better if that was the only statement from the university and we would probably have had a lot less issues. JMO
