You must be a lot of fun at parties. LOL
You seem to be a little full of yourself when you think you alone can determine what circumstances would create an exception to Goss (if Goss even applied). Perhaps this information from Cornell University Law School will clarify it for you.
"Generally, notice and hearing should precede the student's removal from school, since the hearing may almost immediately follow the misconduct, but if prior notice and hearing are not feasible, as where the student's presence endangers persons or property or threatens disruption of the academic process, thus justifying immediate removal from school, the necessary notice and hearing should follow as soon as practicable. Pp. 577-584."

It seems that you are alone among legal scholars in declaring the system unconstitutional.
A police report is a public record. It identifies the alleged victim. That information has famously found it's way to the public on numerous occasions. For example, the girl that accused Winston of rape was publically outed, vilified and eventually withdrew from school. The student conduct council certainly provides a better chance of remaining anonymous. You are still grasping at straws and alone in your flawed conclusions.
No visible progress? That would be because student privacy laws prevent the release of information to the public. What you mean is not visible to you. It is truly a shame that they are not giving you daily progress reports.
You claim "at least four months where the school didn't give him information at all on the matter." Please provide a link to that information.
