If you've ever experienced this system, it's so weighted against the victim. After you report it, the victim then gives a detailed video interview (it lasts about 2 hours), then depending on the severity of the case the accused is arrested, brought in for questioning. At this point, they start collecting other evidence, witness statements and medical records, downloading phone conversations. This process can take up to a year but it depends on the amount of evidence and complexity. Sometimes it fails at this stage, and the defendant walks free but the accusation stays on his record.
After they've got all the evidence it's referred to the CPS for a charging decision. The CPS make the decision on whether they believe the case has a reasonable chance of succeeding, so the evidence has to be really strong. Only if it passes this stage will it go to the next stage, "Is it in the public interest to prosecute?" Most cases fall down at the first stage. If the CPS don't press charges, the defendant walks free. The fact he's been arrested stays on his record though.
If it gets to Court it's usually been 2-3 years since the victim first reported the crime. The difficulty here is for the victim to try to remember the events clearly and in the way she/he first did when the crime was reported. Add to that the trauma of reliving it and being questioned under cross-examination. Only 4% of rape cases that go to trial end in a successful conviction. What it basically says is that 96% of women are lying.
It's a really long gruelling and exhausting process, not one for the fainthearted. It's not just dealing with the trauma of the event but also the stress of dealing with courts and police.
I've had difficult phases in my life and I can honestly say what I've been through this year has been the worst. It's hardest knowing that he's done it before and has got away with it (which he admitted to me in private) and the fact he's out on bail and could do it again. If he does, the next person might not be so lucky.
I'll see if I can find a link for rape statistics. It's frightening reading though.
