As a child I was basically forcibly kidnapped from an excellent home by child "protective" services, and spent several years bouncing from one psychotic abusive "foster" home to another, entirely on the word of one screwed up middle school principal who shouldn't have ever been allowed within a hundred miles of any child, while one of my best friends just down the street from me couldn't beg for or receive any help from those same scumbags regarding being literally beaten nightly by his drunken asshole of a father, despite multiple reports and evidence from many people (including myself and my mother). My family tried to fight it and was basically given the middle finger by every agency they contacted. How is it so very rare that these sorts of abusive agencies ever get investigated or held responsible for these destructive actions?
