Seriously. You think the process for rehoming a dog is more rigorous than the adoption process? There’s actually no help for some people.
Are you thinking someone asks for a child and gets one delivered. There’s a number of meetings before you’re even accepted for assessment, the assessment is about 6 months (at very best, most are much longer) worth of meetings with social workers, there’s a report written at the end of that (mine was 70 pages long), the report is reviewed by a more senior social worker, an adoption penal (mine had 14 people on the panel), who decide whether you can ever adopt a child, and that decision is reviewed by a senior manager in social worker.
After that they find a child for you to be matched with. That involves meeting yet another social worker, the child’s foster carers, the agency paediatrician, any other professionals involved in the child’s life and another report which outlines why you’re being matched with this particular child. That report is then read by another panel who decide whether you’re the right match for this particular child. The senior social worker manager then signs off that decision.
You then start a planning process for introductions, which is when you get to know the child and the foster carers teach you what this particular child needs in terms of care. Once the child moves in, there are regular visits from social worker, and yes they may be unannounced.
After all that, if everything is going ok, you can apply for the adoption order.
So these men managed to manipulate a pretty long, involved process, with many eyes on them, for quite some time. Abusers playing the long game, as they do.
