"That’s me being logical. In mum mode the bitch should rot in prison until she dies"
In that case so should her mother, who from what I've read, and as you've stated, hardly was a caring, well functioning parent.
Tracey Conelly was a child herself once, a child who was abused. But we only care about photogenic toddlers, not about those who grow up to do ugly things.
There needs to be more help, more support, more interventions for those who have been abused. We need to spend more money on child protection - social workers won't always get it right, but how much better could they do if there were lower caseloads?
If they had proper support from experienced colleagues? Locally we've lost a lot of the most experienced social workers, replaced (if replaced at all) by cheaper, less experienced staff.
Been abused yourself? Try getting support, psyching yourself up, phoning up and being told there's a 9 month, 12 month, maybe longer, waiting list.
These services should all be properly funded. All of them. But they're not, the situation is getting worse, all in the name of saving money and austerity, but it actually ends up costing more. More money. And more importantly, more wasted lives.
