I would assume that being higher up they would be able to have a say in some of this. Why are they never asked or consulted? It's weird.
Because the problem is the Juries.
Rape Crisis and many other groups have been trying for years to raise awareness, and on one level have got (some) police and the CPS to recognise their male focused approach of the past harmed and let down women.
But they can do nothing about juries.
ie this is about the great British public and their attitudes.
And as said upthread, even when a jury thinks a man is probably guilty they care more about the impact on his career / reputation than they do about women being believed, and make sure the guilty man is punished.
As I mentioned up thread, there was a campaign to get rape trials to be jury less, but when Scotland tried to do this is got rejected.
Another suggestion was to mak juries who were going to be part of a rape trial, under go training / awareness.
So often when cases are not put forward for trial it is because both the police and the CPS know that the evidence in a case is the type of evidence a jury will not convict on.
It would almost be better, if this is what they are doing, that they make a public statement that they think there is a case, but based on actual trials they think a jury wont convict.
Instead, because in terms of them being monitored they want their stats to look good, so they only put forward "open and shut" cases ie meaning cases that an anti woman sexist jury will convict on.
