I shudder when I hear of drug addicted parents, especially when its a high-maintenance drug like cocaine, meth, crack. I know (as in KNOW) that women and some men will trade sex for drugs or money to maintain the addiction. And far too many will trade their children for paid sexual abuse.
In the drug underworld, there are ZILLIONS of predators who will leverage a parent's addiction and lack of funds in order to rape the kids under her care. The cases are NEVER reported. They are only caught by happenstance IF and ONLY if there's a bust while the child is being abused.
I know of one local coke-head bio-mother who's full time job was pimping out her little girl and little boy to such a degree that the kids were barely in touch with any degree of reality. The boy could not even speak. The kids would sit-around the apartment, naked and watching hard-core porn (and these were kids at about 8 & 10yo-ish).
They would be "busy" with the clients all day and all night. The police found out only in a routine drug-bust of one of the clients. The cops needed therapy and time-off to recover from what they discovered.
A sister of one of my childhood friends was thrilled that her friend (speaking of the bio-mother) got on TV. She thought it was so cool that she was famous. She never even said a word about the continuous child rapes. We later learned that even HER daughter had been similarly sold.
In the town where I'm from, there was a very large and old public mental hospital. It was common knowledge all my life that staff would sell access to child patients during the night-shift. There were staffers who made tons of money that way.
And people call me "nuts" or "volatile" when I call for real justice. I don't give a flip! Until we have truly violent and hideous public punishment of such animals, this crap will go on and on and on...
