That was going to be my next question to you, since you brought up the point about the level of proof and I thought that this might be what you were suggesting as a solution.
According to the graph so very kindly and graciously provided by Polecat Pete,
There is a HUGE discrepancy in the number of convictions in the USA versus the UK. I am not a lawyer, attorney, solicitor or barrister, and not even a resident or subject in Great Britain, and as such I don't know what the standards of proof are in the courts of the UK.
Perhaps this is one of the things that can be considered? Here in the USA, however, I believe that it's extremely difficult to get a conviction unless there is an injury to the woman or physical evidence suggesting that she actively tried to prevent the crime, and so I believe that the standards of proof for a conviction here are rather high.
I actually didn't have a solution to the matter, I was just intrigued by the Home Office's solution, of embarking upon an 'awareness campaign' directed exclusively at men and their behaviors.
