A college disciplinary hearing is not like a criminal case where a beyond reasonable doubt standard is necessary and appropriate. I'm not sure what you two don't understand about that, it's a pretty basic facet of our legal system.
Obviously if the DA wants to bring sexual assault charges, that would be a criminal matter but that has nothing to do with this bill.
Is the evidence presented to the DA at the end of the hearing? The concern is that it will be buried and like you said priority is getting them out of school, which whilst understandable there was an implication of "out of our hair, no longer our problem".
