I take the point that rape is difficult to prove, it's often hearsay without hard evidence, therefore it will not go to trial.
However, I feel that some commenters here are perhaps unaware of the lax service the police provide in terms of investigation.
Any rape victim who reports rape to the police deserves a decent, professional investigation, but that actually rarely happens. Senior police will only be appointed to a rape case if it involves a child, or there is clear evidence of violence and no confusion in terms of the rape (for example if it was committed by a husband or someone known) and whether or not is is 'historical'. Historical rapes are those in which the rape victim did not complain immediately so there is no forensic evidence.
Speaking for my own experience, it was 'historical', involving someone I've known for 20 or more years, and there was no hard evidence, only hearsay.
Let me be clear - I did not expect it to go to trial, given the circumstances and no hard evidence. However, that does not mean that my case should not be thoroughly investigated. It does not mean that junior incompetent police officers should be assigned to my case, and it should not mean that questioning of the suspect does not take place until 6 months later, even though the suspect was available at home, 99 percent of that 6 months.
It should not take two formal complaints to my local MP over 8 months, to have the police actually meet and speak with me about the lax investigation, and, when they have clearly acknowledged the police officer was junior and incompetent, they should have disciplined that police officer, in the same way that I myself would fully expect to be given a warning if I did not do my job.
I am deeply damaged by the experience. I am moving from my home city because this has ruined my career and social life. It has left me with a sense of anger and mistrust that I don't think will be healed, however much therapy I receive.
Until you, or someone you know has experienced police incompetency, or until you have researched the many, many cases in which women have not received justice, you cannot comment with authority on this subject.
