You've answered your own question.
Those further down the ladder should be letting it known to those further up what's going on. If they then don't receive the money it's clean where the decision was made. That's who you blame. If those further up weren't made aware they cannot act.
You think these organisations don't CONSTANTLY go cap in hand to their minister in Whitehall with all the problems the budget cuts cause?
Appointments at the very top of the organisation are political and if you're not cutting back your department until it fits the budget you're going to be out because you have two jobs at that level and one of them is to implement government policy while the other is to run the organisation.
Right there in the article we've got the initial attempt at a police investigation fighting over resources, space and staff with murder investigations and it looks like the murders won out. There's also mention of a social worker voicing concerns about their side being overwhelmed if they tried to take on all the children they had concerns about.
No question has been answered. The budget cuts are from the government. The organisations cut services or try to half-ass as many as they can with the reduced budget. I have doubts ground level staff can be blamed. Oh and the government issued the budget cuts because the country is broke.
So when services fail and the inquiry comes back to say an attempt was made and then got cancelled for budget reasons you would blame... who?
We've got about half a dozen people trying to sell a non-article or inquiry supported line which suggests they're bringing an agenda and not reading the article at all.
