I believe that some parents are gang stalked to the point of mental distress. Once the perpetrators drive the victim crazy, they orchestrate a set up to lock the target up in prison or a mental facility. When the parent is out of the picture, they can manipulate and abuse the foster child sometimes for profit. This is just a small but important portion of the complete non consensual human experimentation program. MK Ultra and Cointelpro style tactics are used for trauma based mind control. It's such a long drawn out process, that the target is unaware that they are going through it until it's to late.
