I have to ask: Had a lot of people received such a text & taken it seriously how many would allow anything short of overwhelming physical resistance prevent them from attempting to dial out?
Though I do accept that shock (from receiving such a text) may have prevented rational rule breaking behaviour (yes, there are rare situations when sticking to the rules even if they have force of law can be a very bad idea) & could easily have given CC the wrong impression of the real situation.
Fairly horrible for all involved, CC included I would imagine.
