My Father Is A Teacher And A Student Has Accused Him Of Sexually Assaulting Her. Camera Footage From The School Proves His Innocence.

My dad is a teacher and high school girls basketball coach. He is near the end of his career, about 4 years from retirement, and has never had issues like this before in his career. The problems are with a student who is on his basketball team. Her family and her have expressed that they believe she should be on varsity, and he disagrees. Shortly into the season, she went to the school athletic director and claimed that my dad pulled on her basketball shorts. She then began spreading rumors to all the students in the school that he grabbed her bra strap and snapped it. My dad’s students, who are upperclassman, did not believe her, but the younger students who have not yet had him as a teacher seem to be buying her story. The school has cameras and a meeting was scheduled between the girl, her parents, my dad, the AD and the principal to discuss her claims. They asked her to name exactly where and when the incidents occurred so they could check camera footage. The camera footage proves she is lying. However, I feel weird about how all of this was handled. The school’s response seems borderline lackadaisical to a sexual assault claim, and my dad says he is thinking about just quitting coaching and keeping his head down until retirement, however, these rumors have been spread across the school by now and I am frustrated that the girl has not been punished for her lie. It’s also worth noting that the principal said he was not concerned about the girl’s story, as she apparently has some kind of history of telling lies and getting caught up in drama like this. But still… stories like this can really destroy people! Any advice on what actions should or could be taken from here?
