A rule made by the residents that people could have broken if they so wished, you mean?
Look, I understand what you are trying to say and you’re right that there are many reasons why people don’t report, but it sounds like you’re excusing the neighbours not reporting. “They might have been scared of being called racists…it’s a culture…they wouldn’t class it as neglect”. There is a definition of neglect, someone’s interpretation of that definition is neither here nor there. I am not saying that everyone does report, I am saying they SHOULD. Children are literally dying, why are you so keen to explain why people don’t report like it should be acceptable? “Oh it’s just the way it is on that estate” isn’t good enough.
Maybe we do need to look at why people don’t report and address that, but in this case specifically the neighbours heard horrific things coming from a home with children living there. They should have reported.
