Social workers do a very hard job, sometimes well, sometimes badly. They definitely have caseloads that are too large. There is definite underfunding.
A horror like this takes many people not doing enough, or doing nothing. Yes, there will be important changes needing to be made following this to hopefully make it more likely that key players could act effectively.
But ultimately this child is dead because he was murdered by a manipulative and cruel couple. That is why he has died. SS may get smarter and more scrupulous but neither they nor a teacher will always be able to prevent these tragedies when there are monsters like these in the world. They will never be able to do it.
Lockdown is not to blame for his death either. He was known to SS, concerns were raised, teacher was aware. Lockdown should not have been a problem when so many professionals were aware. It's also the case that we as members of the public have a responsibility to report. Individuals saw him (despite lockdown) in the days leading up to his death and should have raised the alarm.
This murder took a village but ultimately it happened because the people convicted of the crime carried it out.
There are no words.
And any lessons that can be genuinely learned, bring them on. What else do we have.
