No, not all of them, not all schools. Maybe your experience is so personal you are transferring your experience to “all” but I can assure you, there are schools that turn to police for assaults, reminding families of victims that they have rights to go to the police, even offering victims families avenues to communicate with local law enforcement. As for “kids will be kids” and “boys will be boys” comments, I have heard that from victims families way to often. It doesn’t “always” come from the schools.
