I know someone that was accused of rape years ago in school. Expelled, lost scholarships, reputation ruined. All from some 'arbitration board' with no trial. Thing was, the girl was a frequent liar and had a grudge against him for kindling a relationship then going off to date someone else. The group of friends connected to her, me included, all knew that. This guy was not the shady or violent type at all. He had never even been to court before that.
My friend even claims he was with him that night but since we lived in the same building he had no proof.
None of that mattered, they decided that he 'might be guilty' on her word and proceeded to ruin his life. The exact thing courts were created to prevent, arbitrary justice with no laws and a low standard of evidence.
Maybe we need a simpler solution. Cameras in all public areas of student housing would catch a much larger proportion of rape. But no, that's too simple, we need to change the laws so it's possible to get your life fucked on someone else's word
