The have been a lot of people unjustly accused of sexual assault, not that sexual assault should  be ignored. Universities are often the venue. In the US the universities have taken it upon themselves to act as judge and jury without reporting to the police. Theoretically that encourages women to come forward but it also denies the accused due process. If found at fault it can destroy your life. There is no perfect way to deal with this, but felonies do not seem to be the business of a university. Our courts provide protection from faulty evidence and our judges are trained to deal with the complexities involved. We often underestimate the skills and compassion of our jurists who are there to provide fair trials.
