KenV, I agree.
I think I understand why Courtney is (so far) politely requesting that people button it. He is doing so out of fairness. Speculating on the cause of the accident, pointing fingers, suggesting legal consequences.... it's not fair, is it? It's not fair on Andy or his family, it's not fair on the families of the victims, and it's not fair on the event organisers.
Perhaps it's for the best that we let the experts do their job? They will have the answers.
