I've dealt with school staff who seem to get off on having power of students. Like they go out of their way to bully some kids or they enjoy enacting harsh punishments.
I also think the police officer turning off his body can to intimidate a child should be fired. We need to pass laws that prevent this.
Our dean of students in high school was an ex-marine. And it sure seemed like he decided that he learned valuable lessons about how to treat other people in boot camp.
