I agree with OP's premise, although I think the thread title is unfortunate.
It's about the reporting.
There was no doubt about these rapes having occurred because the rapist recorded them.
I think part of the reason for the shock everyone feels, and a large part of the reason for so many victims having fallen foul of this man, is that men do not have this on their radar.
Heterosexual men, going out for a piss up, do not take account of potential rape .
Women and gay men do.
If this man had been targetting women I think he would have had a far lower success rate because most women, however drunk, would have said no thanks, I don't need a warm place to wait for a taxi, or somewhere to charge my phone, I'll just wait here for a cab.
Because we do take account of potential rape.
If that difference is taken on board, there could be a positive outcome to this .
I won't hold my breath.
