OK, I'll reply....
You're comparing US cases (none of which are for rape) to a rape case in Ireland (oh and some people would argue that Zimmerman didn't "get off" since what he did was not illegal (and the courts agreed he did nothing wrong). And of course, you imply that fame and money got them off, but where's Zimmerman's money? His fame?
And as for the DNA, Conor's already (tried to) explain that away by admitting they had sex. His DNA (semen) is not evidence of a crime. The evidence is everything else (injuries, blood-stained clothes, video footage, etc.) but the only way his DNA helps convict him is if she fought back and it was found under her nails, but even that could be easily explained away.
Look, based on all the publicly available evidence, information, and Conor's history/trajectory, I'm pretty damn sure he raped her, BUT you really are off base with most of your posts.
