noyoucan't the stern report and other studies have noted many shortcominsg in the police/criminal process which are lacking
things like
police buying into "rape myths" eg she was drunk and what did she expect and treating the complainants accordingly
police "on the ground" beliveing that most women are lying and treating them accordingly
evidence not being collected
evidence being collected too late
complainants being discouraged from pursuing the complaint - "this won't go anywhere love, is it worth the trouble"
the CPS only being prepared to prosecute the more "cut and dried" cases
and so on
In the case of john worboys 12 women reported him before he was arrested. These women all told the same story, yet it took 12 before the police made a move. Why? Because, despite these cases going to the specialist rape unit (sapphire), many of them were not believed, were dismissed because they had been drinking, were told that a black cab driver wouldn't do that. I read somewhere that one of the victims said police laughed at her.
When the police and prosecutors start taking it seriously, maybe then we will start to see improvements.
Some women even have to undergo physicals by male doctors FGS. I am sure that in itself makes a lot of women change their mind about proceeding.
