It's the New Zealand way to have a bit of a witch-hunt after something goes badly wrong for a national rugby team at a big tournament.
Usually they don't turn up anything that most people didn't already know. But, asking a few questions in the wake of the men's Olympic sevens catastrophe could be quite enlightening.
Here it seems that a thorough review could reveal plenty - not to apportion blame or besmirch reputations, but to get some clarity on how to do things better for the 2020 Tokyo Olympics.
And probably more importantly, one early truth to emerge is that if New Zealand is to compete in sevens with genuine hope, they will need greater sums of taxpayer cash.
And to qualify for more of the public purse, New Zealand Rugby is going to have to lift the bonnet on its entire approach to sevens and ask hard questions about how much and where they allocated resources, selections, the coaching appointment process, high performance culture and contracting structure.
