This post is about rape, not murder. If I had to guess which profession has the highest number of rapes, I would guess teacher.
No, the post is about power, and the ability to abuse it.Or did you miss the part, where he threatened the mother with deportation?
Anybody can call immigration. Teachers have control over kids. Police have authority but adults have more rights than children. The mother has some blame for not telling someone and letting that happen to her child. American women let it happen and don't report it also.
