In the context of the interview with the CEO of Alton Towers it was not relevant for Kay Burley to press him to reveal details about the injuries of the people involved in the incident.
She should have directed her questions elsewhere.
However, it may well become extremely relevant if it transpires that these very young people with 'life changing injuries' have an argument with insurers.
Those insurers would have been busy talking about that from day one and they are as hard as nails. I don't think it is inappropriate to ask them about it.
Shall we all just brush it under the carpet because some people think it's a bit unseemly to talk about these people's injuries and other people's safety?
