I would doubt it.
Privacy, data protection, I mean I'm sure they would say no.
I also wonder if there is even a central database. Big orgs esp public sector are a nightmare to get joined up. Historic systems, different things going on in different areas. I mean maybe they do maybe they don't.
And if the files can be seen then what will that do?
Police only record gender and it's self ID..I would imagine that this tracks through the system.
So it would need to be each file gone through for eg victim testimony to see what the rape involved.
And anyone outside the justice system looking at that will be a hard no and that's a good thing. Rape victims are anon for a start. Incredibly sensitive testimony.
So sorry I don't think that's a a starter.
I would also suspect the CPS stats are compiled from reports from various areas or branches of whatever as per the police.
I mean all this is guesswork and happy to be wrong but that's my take from how things usually work.
