What did Caroline do to the proffesrs
She didn't use their titles, for a start. Called them by their 1st names. (The people arguing for self ID were all afforded correct titles, IIRC).
And the contempt openly dripped from her and her colleague. They gave a hostile interrogation, an accusatory grilling, whereas the 'experts' for the other evidence session were treated with utmost respect and deference.
It's really quite eye opening watching the two evidence sessions and comparing.
