Oh yes, to save face, protect their "reputation", and not to be publicly recognized and shunned as the sl*ts they are. They perfectly know that today they'll believe women even without evidence, and after all, what is ruining a poor young man's life and career? At least their reputation is safe.
I remember a case, in which a guy saved his *** from a false accusation because he made a video of the girl, showing clearly that it was consensual and that she was even enjoying it. After the trial, the video "accidentally" ended up online. Nice payback against the little tart.
