I don't know anything about the current news situations this thread refers to - I am not in a very strong place right now and have deliberately stayed away from the news because of this.
But I will say that although it is not the same as abuse, failure to protect a child, or being a paedophile apologist, is unforgivable.
I told a teacher about the abuse my uncle had put me through as a child, when I was 13 (years after it had stopped). Police and social worker visited of course, as my teacher had to take it further. My mum cried... made so many excuses for her brother. Later my parents told me they'd 'had suspicions' at the time.
My uncle admitted what he did to their mother. My mum knew this. She begged me not to prosecute and made it quite clear I couldn't take it further. So I didn't.
I am as 'over' the abuse as I'll ever be - but I'll never get over the fact my mum chose him over me. I have only recently started to understand how disgusting her actions are, it has been becoming a mother myself and reading threads like these that made me realise that I didn't deserve the treatment I got.
With this long-overdue epiphany has come the realisation that if I'd told my parents instead of a teacher, nobody else would ever have been told.
