Sentencing guidelines in respect of rape and sexual assault need to change if women are to be adequately protected.
Judges are under an obligation to justify minimum tariffs according to sentencing guidelines. A sentence that does not stand up to scrutiny in the context of those guidelines is easily overturned on appeal.
Similarly, the CPS is not necessarily at fault for not bringing cases to trial. Their remit is to ensure that there is at least a 51/49 chance of securing a conviction, something that is very difficult in the case of crimes that tend to be committed in private or secluded places.
If the CPS guidelines were relaxed, more rape and sexual assault cases prosecuted and the conviction rate fell as a result, the MRA nutjobs would cite this as evidence that women made lots of false allegations.
What is needed is a root and branch review of the way that sex crimes are dealt with in the criminal justice system. I'm not convinced that the adversarial system is an appropriate one for dealing with sexual assaults, but it needs wiser people than me to come up with an alternative.
