TTT's post is laudable. I very much doubt that anyone anywhere condones even the smallest part of any of the story cataloguing this tragedy. Is it a unique case ? I doubt that just as much. Will it happen again ? I am more certain about that than I am what the weather will be like 12 hours from now, in fact it is highly likely to be going on as I write this. Are systems failing in the UK.....? Lots/most to varying degrees. "Sorry" is a useless word to utter, always has been since the first child was forced to mouth it, over some trivial point of politeness, without even understanding its originally intended meaning which requires genuine regret.
