Nowhere in the world is 100% safe is it? It's about acceptable risk, isn't it? I would certainly never have imagined the series of events I think happened, could happen. It has often occurred to me, marshalling at the bottom of Bray that a bike dropped there at what? 180mph? hitting something... kerb or wall, could bounce in any direction at all for a very long way, not to mention bits flying off like giant shrapnel.. and it happened, but at Joey's not Bray.
Who would have predicted the awful accident last year on the road, where a young lad out cycling was hit by a runaway wheel... Life is full of risks, and we have to look out for them, do what we can to rule them out, and then get on with it.
When it does all go wrong, we have to look at what happened and see what we can learn from it, if anything.
Like you, I'm not sure what is so secret, but I suppose while the inquest is to come things may be sub judice. Revealing something might affect the way witnesses described what they saw?
