It has been said Bacons had more than adequate publicity, and I certainly don’t believe the Head was protected from legal action by any notions of ‘Authority’ or ‘Celebrity’ had such action been possible.
Bacon did get more than adequate publicity, I agree, and well deserved. But the publicity was only long after the event. Had people been aware of the high number of instances of corporal punishment at the time, there would undoubtedly have been a hue and cry about them at the time.
