No issue at all with the attendance secretary reporting this. By law, he has a duty to do so (which is why all the others are professionally hanged). Copying the surveillance video, which he probably downloaded to a personal device without school permission, and then distributing it to the media (even with permission from the victim’s parents) is not a good way to ensure job security.
That being said, the clip of the AD walking in on the coach and the student, then walking out smiling is disgusting. This is on a similar level to the Park Tudor situation with Kyle Cox. A scumbag coach with an invincibility complex that bit him.
