@mayjay this is where I equate it to our current political climate. I don't necessarily need proof of specifics that were investigated, but I need proof that an organization in whose integrity I have complete faith has investigated (maybe monitored is the better word) and found them to be operating in an ethical manner. But I'm not sure such an organization exists or is empowered to do so, and I don't have faith in the school regulating itself. So barring having an organization i can trust, this makes the thought of transparency of output of the investigation more appealing. And I think we can agree, that's a path that is much more difficult to navigate as everyone wants their own facts and has their own stances on the particulars.
While this Preston situation is unfortunate,it at least gives me faith that we are monitoring ourselves.
Beyond all this, doing away with the one and done rule would solve 90% of the problem.
And I get where you're coming from. The current paradigm is just not maintainable.
