The names of those rape victims?

John didn't fool anyone. There is no way anyone could actually mistake him for a chick even under the most generous of circumstances. I'm talking even after all of the cosmetic surgery -- prime "Brianna", as it were. Back then though no there is just no fucking way. First of all, he is like 7' tall. Secondly, even after this long he doesn't have any of the female body language down. And finally, he wasn't even a particularly androgynous looking dude to begin with. So sure, maybe he got pounded out by lonely truckers or degenerates with no options who he met on AOL or something, but there was certainly no case of mistaken identity.
The image below provides all of the evidence anyone needs to prove this beyond any reasonable doubt.
