If a school is informed of a student who may be a hazard in the future, the standard of "reasonable doubt" does not apply. Whether they expel him to protect other students from harm, or to protect their financial interests, doesn't really matter. If they allow a known hazard to continue, they are now complicit and will have to shoulder the blame for whatever happens.
Yeah, but so what?
This amounts to accusation = punishment. You find that acceptable?
Yeah, so what? Every job comes with a set of expectations and obligations. A school Admin is expected and obligated to keep the campus safe and ensure the financial survival of the school.
And herein lies the heart of the problem.
The interests of the school in keeping the people safe are not the same as the interests of being fair to the people.
Most people who are accused of a crime are guilty. Should we dispense with trials as simply throwing them in jail would make the population safer?
A few years back, Hoverboards were the must have Christmas present. There was no ruled concerning Hoverboards or any other similar devices. When LSU started the spring semester there were two dorm fires caused by Hoverboards being charged. The immediate reaction was to ban Hoverboards on campus. That's an easy call, without regard to anyone's personal right to legally possess a Hoverboard, or the protest, "I don't leave my Hoverboard unattended on a charger." The Amin can't leave a known hazard in place, no matter how unlikely it is to reoccur.
Such actions are about liability, not safety. The same issue with charging applies to all secondary lithium batteries. Ban on size/ban on brand (but how do you identify the chinesium stuff??), don't ban on what it's in.
Life is full of judgment calls and you can't please everybody. If nothing else, expelling one student because of a plausible accusation of sexual assault will likely reduce the incidence of such things.
So trials are superfluous.
It's been a long time since I've spent a lot of time on a college campus, but I know one thing for certain. In those days, sexual assault, date rape, PYL, etc, was very common. Any time I heard about it, I never doubted the accusation. The standard response to the woman, if she bothered to report it was, "You'll know better next time." Expelling the man involved is basically applying the same remedy to him.
So trials are superfluous.
Who said anything had to be fair? No one ever guaranteed either you or I a fair deal in life. This is when Dennis O'Leary said, "Life is hard, wear a helmet".
After spending entirely too much time of my life being responsible for the safety and well being others, many of whom saw it as an infringement on their personal freedom, I've gone slightly deaf to nitpicking the rules(I'll put the safety glasses on if the sparks bother me). You keep conflating a university with the Justice system and hope I won't notice. The school does not have the power to put anyone in prison, so, "Equal protection under the law" is a category error."
The school does have to power to sometimes demand higher standards than the law, which means there may be consequences for failing to 'be my brother(or sister)'s keeper.' Having sex with an unconscious or impaired person is poor keepership. Self impairment is not an excuse.
Since the school does not have a court or a judge, there is no trial. Someone has to be given the task of assessing the situation and making a decision in the best interest of the school. Someone might be going away, but not to jail.
I notice a complete absence of candle light marches by young men who demand an end to spurious accusations of sexual assault.
