The conviction of serial rapist John Worboys has produced a lot of complaints over the extremely low conviction rates for rape. This is understandable, when one considers that most reasonable estimates also suggest that at least 90% of rapes are never even reported it is clear that the vast majority of rapes go unpunished.
Despite what certain fanatics say the low conviction rate isn't due to a tacit tolerance of rape or police indifference but mostly due to it being a uniquely difficult crime to prove beyond reasonable doubt because their are usually no witnesses and the physical evidence is usually indistinguishable from consensual sex (although not in the Worboys case where sedatives were administered).
There isn't much that can be used to dramatically increase the conviction rate without also sending a lot of innocent men to prison as well (the rate of false reporting to the police is probably quite high with the best estimates suggesting that between a quarter and a half of all complaints to the police are false).
So if nothing can be done to increase the conviction rate then what else be done to make the law a more effective deterrent? The only solution seems to me to drastically increase the sentences for those convicted of the crime, because if the probability of being caught is low then the consequences of of being convicted have to be made higher in order to compensate for that.
