I'm not sure I understand the problem with preparing remarks. Preparing remarks seems like a good thing. It was known that students were upset with the speaker in advance.
I just wish the remarks would have been different than what they were and focused on enforcement of the rules, rather than the failed attempt at de-escalation.
