What you have to understand is that victims’ rights groups only function are to push the needs of the victims. Which in many cases simply aren’t enforceable.
Take the NHS. As a service user who has had a bad experience with (for instance), a minor operation. I could complain that the operation was too long, that I was on a shared ward afterwards. However the fact is you can’t rush surgery and unfortunately it’s completely unachievable to restructure every hospital so every patient has a private room. What the victim wants is very different to what is workable in the system, because they’re seeing it from one angle and are not involved in the others.
As I said, the court system needs improving. We need more staff in every area of the justice system. These cases should be dealt with in a more timely manner. And while the conviction rate can be improved, the nature of these cases means the conviction rate (taking into account all complaints) will basically always be low compared to other offences where the evidence is much stronger.
Blaming this on a lack of will, or because rape is treated with disdain, is very very very unfair. Please try harder to understand the real issues and constraints in the system.
