I am not familiar with the case either, but it sounds like issue is with the school. As well as then failing to report, I would like to add to this discussion that schools are not safe.
I believe the statistic is every day in the UK a girl is raped at school.
I know I suffered a lot of sexual harassment at school, although wasn't raped at school.
I think about two years ago there was a story, I think a year or 2 ago about a little girl in primary school and boys held her down and shoved a car or something up her vagina. Now she can't have children when she's older. I have read several posts on mumsnet about in primary school, girls being sexually harassed when changing for PE.
How many suffer bullying resulting in depression, anxiety, self-harm and suicide?
I think this is all pretty horrifying, why are people focusing on home education? Schools are dangerous! The focus should be, why aren't schools safe for children, especially girls? What are they doing? How are they going to make it safe? They are not safeguarding children. Those things cause lifelong damage.
Considering most children go to school and there are significant safeguarding problems, that is where the attention ought to be going.
