How many IQ points do you need to know that was not a good idea - at least without chaining the kids to their beds?
I'd be happy for mom to get away with not being tried because of low intelligence such that she is not being able to meaningfully participate in her defense. Put her in a home for adults with a GPS anklet to track her when she wanders away. Legally unable to consent to having sex, so if when she winds up preggers it's just a question of taking the biomass from her before or after it gets born.
It takes a village to raise an idiot. How come most of the folks living in the village are idiots themselves? (If they cluster together by choice as opposed to coersion/force can we avoid calling it a British Empire style concentration camp?)
stay safe.
