My understanding was that this review was called specifically to look at what happened with the Warboys and Reid cases, to look at the systematic failings that occured in those cases and the systematic failings across the system as a whole. To look at the fact that women who reported these crimes weren't believed / nothing was done.
It would have been a chance to do something as those cases were so high profile and so horrific that the outcome couldn't have been ignored.
The stern report recommendations haven't been impemented AFAIK.
The police know what they should be doing - they just aren't doing it. This might have embarassed them into acting. I think it is a lost opportunity.
The papers which reported this story also said something about "and anyway police forces will be looking at cutting investigations" which seemed to imply that with the cuts, one of the first things to go would be spending time investigating rape cases.
