Did you really need one to see what would happened if these kids were returned to their parents? Despite warnings from pretty much everybody involved in this case, the judge returned the twins to the biological parents and then says he couldn't have possibly seen this coming. The deference the system gives to biological parents who abuse children is nothing short of scandalous.
That you figured out how to mate doesn't, in my mind, give you an automatic right to keep your children once you've illustrated to society you're not a capable parent. I believe the next step should be SOLID evidence you are now a capable parent; something this judge clearly did not have before him. And this case is far from isolated.
