How in the world is the conversation not about the lack of ethics of the teachers and faculty who agree to serve as the amateur judges/questioners in these tribunals?

Hello, I spent a decade of my life learning just how difficult it is to become an expert in my very narrow field. In fact I spend most of my time helping undergrads refine their rank speculation into tractable problems to potentially guide them to a deeper understanding of even a tiny slice of my narrow specialty.

What's that? You'd like me to serve on a jury for the school? No not on a jury, but instead to serve as a kind of combination panel judge and amateur lawyer? For what may be criminal allegations against a student? And you say there's no actual trained judicial expert to lead and constrain the process, but instead a handbook that will teach me in about an hour how to question a witness?

Sorry, it's my minimal sense of civic and academic integrity calling. I really have to take this...
