Warwickshire's chief fire officer, Graeme Smith, had condemned the decision to press criminal charges against the three senior officers who he said had been "treated like common criminals".
But Det Sup Ken Lawrence, who led the Warwickshire Police investigation, defended the case.
He said: "We have a legal duty to investigate every death in whatever circumstances.
"So I would pose that question, how can anyone suggest that that doesn't warrant an investigation?"
And I would pose a question. How does a duty to investigate mean that criminal charges must be brought? Answer, in the box-ticking targets driven, "every incidence must result in a sanctioned offence" world of modern anti-Peelian policing.
It is a tragedy that the four fire-fighters died. But, let's be honest - like being in the Services, being a deep-sea fisherman or, admittedly to my surprise, a window cleaner, you know it is a dangerous job when you take it on.
