What's a scandal that your school/job tried to sweep under the rug?

A stabbing between students, multiple thefts, a girl who potentially killed herself because of severe bullying that the school and teachers completely ignored, multiple fires set around school by students, 2 sexual harassments on minor students from adult teachers. They also try to deny the fact that most of their main teachers don't even have their teachers licenses plus many of them are verbally abusive, physically abusive or both.
