I've spelled out how far it can go. You want someone sacked, you want someone prosecuted.
But I don't see anyone holding a smoking gun. I see a chain of lose-lose decisions being made out of necessity starting with the government saying we're broke, lets make some massive reductions in expenses.
It's really this simple, who do you blame when there isn't enough resources to follow up every report of a potential crime. Just because we have retrospective vision it doesn't mean it was so crystal clear at the time.
I can see people gagging for a name to string up and tear down, I see massive incomprehension as I explain they probably can't ever have one because this is simply expected failure when resources to perform a job are cut.
