People talk of the terrorist risk here as if the IRA never happened and whilst every tragedy hurts major incidents like this are no more frequent than they used to be, it's just that the saturation media coverage 24/7 makes it feel so much more desperate.
I can remember as a kid when the M62 (now M60) west of Prestwich was named Death Valley because of the number of major multiple car pile ups that happened there in spring and autumn fog before we had better impact protection, compulsory seat belts, ABS and sat navs warning us about dangers. Every year there were countless stories about whole families dying in their beds due to poor fire prevention, chip pan fires, smoking, PU foam, the absence of smoke detectors etc where now it's a much rarer occurrence.

Maybe we have become a bit too complacent and felt too safe and have undercut some of the emergency services that have always been there when disaster strikes which has seen a slight rise in fire related deaths in recent years but we're still far safer than at most times in human history.
