One of the previous threads here had a link to a pdf somewhere in the comments, that looked like it had excerpts from the court filings. It had quite a few emails saying variants on "my experience with them says these accusations aren't true at all".
So no, I don't think one student pushing back would have helped.
When you gather that many social justice warriors together in a location where there is no actual injustice to prosecute, they will creatively invent some so that they can do the thing they enjoy doing.
You see a similar pattern with firefighters. When there haven't been many recent fires to put out, you start seeing more firefighters getting arrested for arson.
See here:
"It is important to know that most of the fire stations/departments do not pay for the services of a volunteer firefighter. However, they may get reimbursed for attending training and meetings, responding to fires and emergencies, and time spent on shifts. The amount of reimbursement is generally at the discretion of the fire department."
