There were three adult presenters and 20-30 other individuals in that room, all of whom were there voluntarily and with parental permission when required. That’s plenty of supervision.

When I deal with students, as an educator, I do so with the doors open, and I don't care if the proceedings are taped overtly or covertly. But then, I have nothing to hide.
