I can understand that you are livid, of course not fully because each experience is different, but I hope the anger that you reported it and went through that subsides, because it most certainly was not a waste of time. Even without charge, his name will always be on th e system, so if and when someone reports in the future, the allegation will be taken extremely seriously.there wasn't enough evidence this time, but with your claim.on the police records there really could be next time, so you have done the right thing and it's extremely brave, so be proud of yourself because this could still make all the difference in the future.
The cost are very risk averse. If they know there is not enough evidence for a conviction, they don't tend to take it to trial, there is the cost and they won't want to put you, the victim, through that if it isn't going to go in your favor. It's ridiculous, and the reason why so few result in convIction. My belief is that in a case with one word against the other, proof should not be beyond all reasonable doubt, it should be wHo is more plausible? In these cases, you have two people telling two different stories, one of whom is lying. I th ink, if they say the defendant is innocent, they should be sur enough as to say to the victim they are lying. In reality, this is not the case and when it is decided that a case shouldn't go to trial, they aren't saying you're lying at all, theyre just saying they can't prove that it happened beyond all reasonable doubt.
If my perpetrator doesn't get charged, I expect a call in fie years time asking me to come in to talk about something I once reported, because rapists repeat their offences, theycant help themselves. You did the right thing, and could have made all the difference to any victims that report in the future.
