I agree with you in part LostChild and feel sorry for your hurt but you are talking about a system which has always allowed some bullies and abusers to get away with their evil.
This is nothing new I'm sad to say.
But don't believe or assume for one moment that they ALL get away with it. I know from personal experience, they don't.
I once asked a police officer how he managed to keep his hands off people who had hurt and abused small children and he simply said, 'Oh, we don't.'
And as a prison visitor I saw for myself the damage done to those inside who had hurt children.
Whatever modern innovations they bring into prisons, it is still a very, very grim place populated by many evil, vindictive people whose need for power has a limited audience. So the abusers are targets.
Your case is particularly bad and I hope you are able to talk out your anger and hurt with someone.
The world isn't fair, it never has been but we have to fight to preserve our own souls and, if we can, put down those burdens of anger and resentment. They can only do us more harm.
The abusers have damaged your life but don't let them ruin ALL of it by carrying it with you forever.
If you do, they are still winning, still causing you pain. You deserve better than that. You deserve to win back your contentment and love of life.
