Screw child protective services, they fail

Alright when i was little i was well in a rather bad way ya know? In the are of child services area you could say? well i never got anything but yelled at but if you actually looked at my case their could be no mistake there where pictures of huge bruises, a gun taken from my stepfather and so on. I hoped to god it was an accident, or something unusual, something that was rare. Turns out it's more than common 2 of 3 cases of child abuse just continue until the child turns 18. That only includes KNOWN abuse. Many even die, yet there are almost no laws to save them, to save us. It's considered to sacrosanct to invade the family unit even to save a child.  The same goes for battered women even if they call the police, the cops only calm the current situation or say that it's all in the woman's mind. I hate this so much that no one cares enough to save a child from a parent or a woman from  a bad man. No one cares enough to help other people! Help those you know please...
