One thing I have noticed is that in every case of alleged student acquaintance rape I have read about over the last year where the alleged victim had been drinking, the alleged perpetrator has been acquitted.
At least by this man admitting that he committed the crime of rape under these circumstances, circumstances under which no doubt even in the UK he would have been/still would most likely be acquitted without his confession, he has shown the public quite clearly that this sort of rape is happening under their noses.
He has also openly shown that the perpetrator can indeed be the 'nice' boyfriend/acquaintance who escorts a woman home to 'help them' because they are so drunk. Instead of the poor, confused, innocent, normal man who had been given consent that night, only to find the girl regretted it the next day and so was accusing him of rape.
At least this confession provides a proven example to, possibly, sow a seed of reasonable doubt to colour a jury's collective mind in favour of believing a future victim, in a rape trial.
This is not the same as saying that this man should be forgiven, or that anyone who has been raped can have their experience changed by such a confession. Though, I can only guess it might help a victim a little bit if their rapist at least admitted what he had done, instead of lying and making out that it was her fault and she had given consent.
These sorts of rapists usually have full back up of mates and the tacit sympathy of other men, and of women friends. In schools and colleges the victim is doubly betrayed by their own friends and acquaintances not believing them.
Just maybe, other men who have done the same, will wonder about themselves if they hear of this account. Maybe the women who believe these men have not raped, because they are their friend, because they nice, good looking etc, will think twice too.
